Product Review: Nex Band Smart Bracelet

Nex BandAt CES 2016 (the International Consumer Electronics Show), I saw a pretty inventive company that was making a smart bracelet with interchangeable modules that you snap in an out, and each of these smart modules was programmable to allow different features. Neat concept overall. Honestly, I didn’t write about it until now because it was still a proof of concept and not quite ready to market. It was a neat idea, but it was bulky, and the overall sentiment for smart watches was they couldn’t be too bulky, even for the sake of new and expansive features. But, I kept them in mind for when they evolved their device into a production ready unit.

That’s all changed as of today.  The Nex Band has arrived. Far upgraded from the concept I viewed at CES, this device is no less than incredible and the possibilities are endless.  The video below will show you more of a social aspect to the band. It can be integrated into your home’s smart devices, like garage door openers, gate openers, security lighting, or join with many other smart devices in your home. It has a great social aspect, such as being able to detect close proximity to friends, auto message sends, tagging locations for reminding you about things, like making a Yelp review, or adding a restaurant to your favorites list.

It has a gaming aspect as well. Imagine playing a virtual “tag, you’re it” game while working in a System Status Management agency. When I worked at MedStar, a traditional game was to place a special bowling ball on another crew’s ambulance, in a cabinet, on their gurney, etc., so when they took a corner, accelerated, or braked, they had to call their unit on the air and declare that they had the ball. So every crew tried to avoid the crew with the ball. Sometimes, the mass of six or seven ambulances at a hospital would mysteriously disappear and the ball was left on the driver’s seat. The Nex Band bracelet could be used like this too, along with a “no tagback” rule.

Check this out…

Seems pretty cool, eh? So let’s talk about the serious aspect of the utility that the Nex Band can provide.

Let’s say you have a family member that has Rheumatoid and Osteo Arthritises (sp?), or COPD or CHF. Maybe they’re getting some knee replacements shortly since there is literally no cartilage left in their knees. They also have been given their first smartphone, like a Samsung Galaxy J3 V, with “Easy Mode”. They aren’t moving the best and we’re afraid they might fall again (one visit from the fire department for a lift assist is enough to realize it’s getting worse and they don’t want to be in an assisted living facility). As much as we would hope they would carry their phone everywhere in the house, it isn’t going to happen for a late night bathroom visit, or just to get up and get a meal. Enter the Nex Band. A slip and fall can be dealt with by a simple push of a pre-programmed button that calls their son or daughter, or sends a pre-programmed text message saying they need help, or dials or texts an E9-1-1 PSAP. Another button turns on the speakerphone so they can talk from where they fell. A medication reminder may be programmed for another button. Another could remind them to do their physical therapy and respiratory exercises. Another can open the garage or unlock the front door for emergency responders and turn the lights on.

How about for us in EMS and public safety? We could use it as a panic button for when we find ourselves needing the cavalry on a call, since pushing a button on a bracelet is far more discrete than picking up a radio or phone and calling a MAYDAY alert, and that might get you shot or make you the target of an aggressor. It could be used by a flight crew as well (I’m okay, I need help, MAYDAY, on scene, transporting, etc.).

Do you see where I am going here? There is no limit to the amount of benefit to the pre and peri-hospital and general medical fields. The Nex Band can help with nearly any home therapy or call for assistance we can provide. It can be a safety device for crews that cannot speak or use a radio. And it’s waterproof. It’s still a bit bulky, I admit, but it isn’t like any other smartwatch out there. You can adjust each module from the app, or you can hack each module if you want even more customization. When I saw them at CES, you could even integrate it with IFTTT.

Product Review: Magnum Response III 6.0 Boots

I see this question often on Facebook and Twitter: “What boots should I get for EMS?”

About a year ago, Magnum was looking for wear testers and I signed up to see if I could join in. It’s a neat program that allows you to check out a few Magnum product and you can keep them. They do put out requests for wear testers on their social media pages, so make sure to follow Magnum on Facebook and Twitter.

A few months ago, they sent me a welcome package with a t-shirt, water bottle, some decals, a guide book, and my first product to test and review.  I was asked to review the new Response III 6.o boots.

 

Magnum Response III 6.0 BootsThe last time I wore Magnum/Hi-Tec boots was in the Marines in 1995.  I only got to wear them on duty for about 3 months, then the regs changed and we couldn’t wear them any more. In that 3 months, I completely wore them out. They were comfortable, like tennis shoes. They were very popular among Marines (at least at MCB Pendleton). Since then, I have worn Danner, almost exclusively. Other brands were just not comfortable and able to handle the daily grind of working in EMS and for recreational hiking.

Get Kilted - Get Checked

Get Kilted – Get Checked

That I was able to review these boots was perfect timing for me, with my latest Danners wearing out. I have been wearing these boots for about four months now. They have proven to be quite durable and very comfortable as well. I have even worn them with my kilt during the annual September Kilted To Kick Cancer campaign.

What’s this all a-boot?

I wear a 10.5 to 11.0 boot and these boots fit like a glove right out of the box. I found them comfortable to wear, with good padding throughout the footbed, and they provided me with good arch support. The sole is flexible, but firm. It appears to be a non-replaceable rubber/plastic hybrid. There is a good amount of grip on them with broad grooves (great for channeling water away) and even walking across wet surfaces, I found I didn’t lose even a little traction. The other nice thing is that they don’t collect junk, which is important for me, as I work full-time in our area’s local L2 Trauma Center’s IT Data Centers. One of the two sites I work at has two retention ponds and a creek between them. So, it is blessed with a large flock of annual resident Canadian geese. They leave mushy poo everywhere, and as good as the facilities team is about keeping walkways clean, they are simply outnumbered. It is important not to track stuff into a data center. We keep the rooms as clean as a high-end hospital’s trauma bay. Not quite sterile, but exceptionally clean. Anti-static also is important, and the rubber compound does not disappoint. I walk across sticky mats before each entry to the data centers, and when I step on them, I look at the footprints left and they are pretty clean… moreso than the Vibram soles I have on other boots.

You may think that doesn’t reflect what we do in EMS, but I can tell you that I am frequently kicking freight boxes and pallets, climbing in and out of raised floors and metal server racks, running carts, climbing ladders, and much more. I often catch the toes on snags of metal and server rack doors. I’m pretty rough on my boots.

As far as EMS goes, I have worked a couple shifts and found them to be very supportive for the ankle, easy to quickly put back on when the tones drop. They have one catch on each side for speed lacing. I would prefer true speed lacing loops over the catches, personally. Splashing through decent puddles (1-2″ deep) is no challenge and no water leaks into the boots. When I wear them for 12 hours at a time, my feet come out dry and cool. (Note, I usually wear Under Armour boot socks with any boots.) By the end of the 12 hours, I am ready to take them off for a while, but I’m now in my 40’s, so that seems to be the case with any footwear for me.

I think my Magnum Response II 6.0 boots are more durable than the Shadow Trooper's!

I think my Magnum Response II 6.0 boots are more durable than the Shadow Trooper’s!

The toes are not reinforced on these boots, so if I had the option, I would prefer at least a reinforced toe, or a steel toe option. Ankle support is less than an 8″ or 10″ boot (which I prefer), but not bad for a 6″ boot. I haven’t rolled an ankle on a hike over semi-rough terrain. Aesthetically, they look like black work boots. I’m finally at the point where I feel a good polishing is due. They have held up well to scuffing so I haven’t needed to do that yet.

The Verdict:

Overall, I’d give them an 8/10. I am not sorry I got my hands on these boots. They are comfortable, durable, and attractive. I wear them at work and off duty. They provide good support and protection. They are comparable in quality and durability to much more expensive boots, like Danner. If the speed laces and reinforced/steel toe were available, they’d have scored a perfect 10. Not bad for a MSRP of $79.99.

I’m tired of Facebook EMS forums

Most Facebook Forums

It is more than a little disheartening to find so many EMS forums on Facebook that are focusing on less important issues. You can find hundreds or even thousands of posts with essentially what amounts to gore porn, and asking about the best boots to wear, which stethoscope should I buy, and, literally, “I failed my exam twice. Do you have any tips to pass the exam?” By the way, about every five posts is an advert for Teespring or some other shirt maker hawking stupid slogans like, “I’m here to save your ass, not kiss it!”, and “Being an Emergency Medical Technician is not a career, it’s a post apoloclyptic survival skill!” Give me a break.

What I don’t see much of is EMS pages on Facebook that talk about clinical excellence, best practices, evolutionary tactics and treatments in EMS, alternative uses of medications, expanding our knowledge base and clinical aptitude and competency. So when I do come across groups like that, I tend to stick around, and occasionally I even help admin them. My blog and Facebook followers are higher caliber providers and I know that most, if not all, of you want to learn and be the best medics you can be for your patients. I’m going to give you a list of pages worth checking into for more about actual medicine and less about hero worship and people too lazy to research questions before posting yet another redundantly redundant, no-skill, knowledge-less, drivel ridden post.

Where to look to learn and contribute to the improvement of your care and all of EMS:

Believe me when I say that these pages are chock full of the latest peer-reviewed science and medical evidence. There are some real superstars of EMS lurking in these forums. Big national names, quiet, unassuming medics, flight medics, post-secondary educators, biologists, attorneys, expert witnesses, ER nurses, EM physicians and medical directors, public health people, and yes, there are some egos that tend to bump heads, but there really should be all of that. Without some vigorous discussion (that doesn’t decay into a childlike tantrum), we may never see improvement. It’s fun. It’s the stuff you’ll need for ACLS EP/CCEMT-P/FPC/CCP preparation, protocol and guidelines development, tips to improve your presentations, and oh so much more. Closed groups are closed to keep the average time-clock puncher out of the way. If you can be serious about what the forum exists for and use it to sharpen your sword, then ask to be let in. Most likely, you’ll get in. Be prepared to see far more than anything you’re likely to encounter in an ordinary EMS CE course.

Kilted To Kick Cancer Campaign 

Kilted To Kick Cancer LogoSeptember is Prostate Cancer Awareness Month. I volunteer my efforts to support a 501(c)3 nonprofit organization called Kilted to Kick Cancer. All of September, an army of men wear kilts when practical to start the conversation, because people are naturally inquisitive about “what’s going on under there?”

This conversation starter opens the door for us to proselytize about male-specific cancers, including Testicular and Prostate Cancers. People openly talk about Breast Cancer, and you see pink ribbons and shirts all over. Rightfully so. 1 in 7 women will be diagnosed with Breast Cancer in their lifetime and 1 in 30 will die from it. The PR machine for raising awareness and funds is tremendous. A few women in my family have died of breast cancer, which can put my own daughter at risk.

As serious as those statistics are, we pay attention to them, but men don’t really talk enough about their own sex-specific risks. 1 in 7 men will be diagnosed with Prostate Cancer in their lifetime and 1 in 30 will die from it. You read that correctly. The statistics are the same as for Breast Cancer.

Get Kilted - Get Checked

Get Kilted – Get Checked

What can you do about it? 

First, talk about it! Let’s make it as conversational as Breast Cancer! It is no less or more serious.

Second, get checked. The PSA blood test is far too unreliable, so you need to get the gloved finger treatment. Don’t like it? Suck it up! Women have mammograms done annually and they’re uncomfortable. Women also have pap smears annually. They endure. Man up and get in to your doctor annually and get it checked. If found early, it is very treatable.

Third, visit www.kiltedtokickcancer.org and make a tax-deductible donation for Prostate Cancer research. Click on the “Donate Now” button. You can make a one-time donation, and new this year, you can make a monthly donation. The donation billing form has a place to select a team at the top and I’d appreciate it if you select “Team Unwired Medic” so I can get some bragging rights with other fundraising teams. Thank you!

Fourth, make your own team! Get Kilted! Become a champion of this cause! Then go forth and spread the word and fund raise!

 

F.A.Q.:

Do I have to be Scottish to wear a kilt? Not at all. In fact, utility style kilts, like the ones found at Alt.Kilt are getting to be quite fashionable and a regular sight! They’re extremely popular at fairs and events, like Burning Man. There are other, inexpensive ways to get kilts, but they are not made as durable as a traditional Scottish kilt. Economy kilts can be found at many places on the web, and they’re great for wearing for less formal occasions and for daily wear. I got my Leatherneck Tartan kilt as a package with sporran, sock flashes, kilt, and shirt at Sport Kilt. The royal blue utility kilt (seen in picture above) was a project my mother-in-law helped me make and we found patterns with a quick search on the web.

What’s the difference between a kilt and a skirt? A kilt has an apron in the front and is pleated all the way around. A sporran (the bag that sometimes has tassels on it) is commonly worn with a kilt, but not always. For the rest, I will have to leave that to your imagination. 😉

What do have going on under there? It’s a kilt, not a skirt! 😉 Also, see the previous question.

Can I start my own fundraising team? Absolutely! Either use the contact form on the KTKC website, or e-mail justin@kiltedtokickcancer.org

Do you play the bagpipes? Not yet. They’re a bit pricey, at least $1400 for a decent set and I have my eye on a custom Marine Corps edition for $5,800, but I’d be happy to learn if I could get my hands on one. Playing the bagpipes is not a prerequisite for wearing a kilt, and in fact, when playing the pipes, a different style kilt specifically for pipers is worn.

 

More articles to read about male-specific cancers:

Note: My blog links will include other links to kilt makers, D-I-Y kilts instructions, and much more…

EpiPens too expensive?

So it’s all over the media and social media platforms. EpiPens have jumped in price more than 400% in recent years. I was advised by my allergist to carry them in 2007, and I did for about 4 years. Then they became too cost prohibitive, and that was when they weren’t in the $400/set range. I had to stop buying them every year.

Fast forward to last year, and I suddenly have an episode of anaphylaxis and status asthmaticus. I spent a few days in the hospital and was on high-dose steroids for a couple months.  Those EpiPens were looking like a bargain now. I was able to get a set of Auvi-Q epinephrine autoinjectors, but they were later found to be ineffective at delivering full doses so they were recalled and I got EpiPens, which were now (again) without competition in the marketplace.  Lack of competition means that their dollar and fifty cents worth of drug in an auto-injector could be priced at whatever they want to price it at. Even with insurance from my primary employer, they were cost prohibitive, so I went to the EpiPen website to see if they had a copay savings card, and they did. My card reduced my copay to only $5. This year, the makers of EpiPens made the copay card even better by reducing the copay to ZERO dollars and it is good for up to twelve EpiPen sets (the two-pack, not the singles) per year. Then the card expires and you have to sign up again.

EpiPen Copay CardThe only requirements are that you have a commercial insurance plan, and you are over 18. If that fits you, then go to their website and sign up and print your card, then take it to the pharmacy. The bad news is this is for individuals, not for organizations like volunteer fire and EMS, and if you have Medicare, Medicaid, or TRICARE, you are ineligible.

TempTraq – Product Review

TempTraq is a wireless temperature monitor for consumers, but it has the potential to be quite useful for healthcare applications and for prehospital/perihospital care.

How does it work:TempTraq by Blue Stacks Technologies

TempTraq by Blue Tracks Technology is a single-use device for wireless temperature monitoring that is compliant with ASTM E1112-00 (standard for accuracy in digital thermometers).  It uses a simple push-button activation on the temp probe that activates it and then it has a life-span of 24 hours after initial activation.  You connect to the wireless temperature monitor via a smartphone app for Android or iOS and your device’s Bluetooth connection and can configure the app to display Fahrenheit or Celcius.  The wireless temperature monitor connects with the app and your smartphone using a unique identifier.  The app has the ability to allow the user to configure parameter alarms, for instance, in case a temperature spike is encountered.  The app gives digital and graphical readouts of the monitoring results.  No patient identifiable info is transmitted via the temp probe, so if an eavesdropper comes in to range with several of these devices in operation, there would be no way for them to know which device belongs to which wearer.

Although the technology is still confined to the consumer workplace, it could be of value to us in EMS even now.  Temperature monitoring with a full capability monitor is not always feasible.  Think of Foley temp probes, for example.  Invasive and expensive.  This would be useful in monitoring a febrile child with seizures or an infection and could be transferred to the receiving hospital upon transfer of care.  If a patient were to be seen in an Urgent Care or ER, then they could be monitored periodically by staff to see if their fever has broken or spiked.  Oncology units could use this to monitor patients receiving chemo infusions.  Long-distance transfer patients could also be monitored for temperature spikes.

My product evaluation:TempTraq Wireless Temperature Probe

TempTraq wireless temperature monitoring was easy to get going.  I downloaded the free app from the Google Play app store and got it running with Bluetooth active on my smartphone.  I simply followed the directions on the packaging for the wireless monitor and applied the temp probe to my left axilla.  I connected it by performing a search in the app for the unique “Patch ID”, which you can customize with a personalized name (perhaps a child’s or patient’s name).  You can monitor several devices at a time, so let’s say you have a house (or waiting room) full of sick kids and you need to track all their temps, you shouldn’t have any problem as long as you are within a few yards of the person wearing the TempTraq, which should be easy to achieve in a waiting room or in a typical single-family home.  It is removable and re-applicable for bathing and should not be applied over any open skin wounds.

TempTraq App ScreenshotIt would be easy to see first responders and prehospital care providers use a system like this.  Say a first response crew arrives on scene, they could add this device to the patient’s axilla in a clinically appropriate situation, and then activate it, documenting the findings.  When the patient care/transporting crew arrives, they can assume monitoring and collect all the temperature recordings logged to that point, and continue monitoring throughout transport.  When care is handed to the hospital staff, they can keep using the system and uploading the temp logs into the patient’s chart.

I wore the monitor for a full 24 hours.  It was noticeable, but not uncomfortable.  I can imagine a toddler absent-mindedly picking at it.  The adhesive seems to be consistent with hypoallergenic tapes, making it usable for sensitive skin.  The monitor collected readings of my temps throughout the night while I slept and when I reconnected the app and phone, it downloaded all the data from the time of my last connection.  In short, it worked exactly as described.  I did not attempt to induce any false temperature elevations during my trial of the TempTraq.  The app allows custom alerts to be sent and allows the user to add notes, like when a medication is given to the wearer (for example, if Tylenol is given to the wearer with a fever).

What would I make different:

I think the product documentation could be slightly improved by explaining the normal ranges of temps for axillary temps versus oral or rectal temps.  The company is already working with various health partners in the US to integrate readings into EMR systems, like Epic.  I had to perform a hard reset of my Android device after using the TempTraq and as a result, I lost all the data from my product trial, so there is no cloud account to retain information.  The simplicity of the app is a strong benefit to using it, giving a very small learning curve to the user, which helps eliminate confusion in usage.  Otherwise, I don’t see any need to improve or modify the system.

I wish to thank the reps at TempTraq for giving me this opportunity to review the TempTraq wireless temperature monitoring system.

O2 Amp Vein Glasses – Product Review

So I’ve seen these glasses advertised around the web and on Facebook talking about how EMT’s and Paramedics are using them to see veins for IV starts and to identify blood pooling, such as in hematomas.  I reached out to O2 Amp by 2ai Labs, and they sent me four different sets of these glasses to evaluate and report back on.

The Claims:O2 Amp by 2ai Labs

See veins more distinctly, identify blood pooling, see shifts in blood concentration in tissues (i.e., blanching, or capillary refill or lack thereof).

The Premise; How does it work:

Color shifts in vision can enhance the viewing of certain color spectra, allowing the user to perceive certain colors with more intensity, such as veins and capillaries.

By tinting the lenses, a color shift is introduces that obscures the undesirable range of color and enhances others. This is a tough one to tackle, because people don’t all perceive colors identically. For instance, I have a bit of color-blindness, which is not uncommon for men. I noticed that I perceived some things less intently than other users I shared this experience with, and other things more intensely than others.O2 Amp Glasses by 2ai Labs

In order for most of these glasses to do what we expect of them, you will require a pretty strong light.  In fact, the manufacturer recommends you start learning how to use these glasses in full sunlight.  I agree.  Alternatively, exam lights and tactical flashlights offer very strong light to help make these glasses work for you most efficiently.  My best results were obtained in direct sunlight.

My results:

I tried taking these to our only regional trauma center’s ER and worked with a couple nurses and a few medics that passed through while I was there.  Results were not exactly overwhelming.  Even with a tactical flashlight emitting over 300 lumens, I and the others that were using them were still not feeling like we had fared any better with or without the glasses.  There are a couple possible reasons that things didn’t go so swimmingly:

  1. Doubt/Bias: Any product that claims to allow one to perceive something differently by just applying a tint to your eyes seems dubious.
  2. Experience: We work under ostentatious circumstances and we in the ER and in the field are often called to be expert phlebotomists, finding veins where there seem to be none readily available and starting IV’s and performing blood draws.  We have additional training and experience in gaining IV access beyond the typical clinical provider.  The only medical staff I have encountered that are on par with emergency personnel are surgical suite medical staff and blood bank phlebotomists (incidentally, I worked in a whole blood donation bank for almost a year and that is where I gained a significant portion of my own phlebotomy skills).  One nurse who tried the glasses said maybe I should take these to the floor nurses and let them try, since they don’t do too many IV’s comparatively.
  3. It’s a scam: Yes, it’s possible, but I don’t think it is likely.  I have read the literature provided by the manufacturer and I don’t believe it is a scam.

O2 Amp Oxy-Iso SunglassesI also took these glasses to my EMS station and worked with a few fellow medics to see what they thought.  We were already outside doing simulations and it seemed like the perfect time.  Of the four varying tints of glasses we tried, they all yielded positive results, but the darkest of the purple tints, the sunglasses style O2 Amp glasses, showed the most benefit in finding veins.  Tactical flashlights just didn’t do these glasses as much justice as the sunlight.  Maybe the LED doesn’t emit a broad enough light spectrum to compare with sunlight.  The end result was that provided you had a bright enough light, like sunlight, they worked fairly well.  In the back of the ambulance with all the lighting up and the tac light, you could still do well with these glasses.

My verdict:O2 Amp Oxy-Iso Sunglasses by 2ai Labs

The O2 Amp glasses by 2ai Labs are a promising development in rapid vein identification.  Caveats are warranted for people with color blindness – your mileage may vary – but that is why I enlisted the help of many other practitioners to help me properly evaluate these glasses.  As the manufacturer claims, they are an alternative to the more expensive Vein Light devices.  They seem to deliver fairly well, when placed under more ideal circumstances.  They may not be the best in helping in low-light circumstances, of which EMS’ers find themselves in abundance of.  I’m happy to have been given the opportunity to try these glasses out.  On another note, I have been in contact with the manufacturer several times since receiving these glasses, and they have been helpful in ensuring I get the best results from my product evaluation.  I think their customer service has been excellent.

Bare Arm - No Glasses

My forearm in bright sunlight. Decent enough veins.

Bare Arm - Oxy-Iso Glasses

Bare arm in direct sunlight. Oxy-Iso Sunglasses placed over the lens of the camera. Results in the image are not as evident as with the naked eye. The blue tint in the veins is more prevalent. Smaller, less bulging veins are more noticeable when viewing through the glasses than through the camera. The difference is probably due to automatic color correction of the camera in processing the digital image.

 

 

 

 

 

 

 

 

 

 


Update:

I have been asked by O2 Amp to include the following notes, which may help their users get the most out of their glasses purchase and to clarify some of the science behind why their product works:

Thanks, Chris, for reviewing our product.

Some follow-up notes:

(1) We like to emphasize that, If one should be wearing protective glasses anyway, then one might as well wear glasses that enhance health signs and veins. If lighting conditions are good, then you get perceptual advantages. But if lighting conditions are not good, well, then it becomes basically clear protective eyewear. So, we view them less as a competitor among the vein finders, and more of a “wear these protective eyewear instead and you’ll sometimes — with good light — get perceptual advantages.”

(2) The Oxy-Iso is stronger in some sense, indeed, than the Oxy-Amp Paramedic Vein Glasses. But (a) the Oxy-Iso also cuts out a lot more light, making it even more difficult indoors, and (b) it blocks the other blood dimension we can see, variations in concentration of blood (what the green Hemo-Iso amplifies), making one better at seeing veins, but potentially worse at seeing clinical signs more generally. That’s why we recommend the Oxy-Amp Paramedic Vein Glasses to paramedics, because it blocks only a very narrow band of bad signal (and the light pink is a functionless side effect of the way we have to manufacture it), and so leaves one’s general clinical sense unhurt, but only better. …because paramedics need their general clinical signs sense intact.

(3) It’s more than just tints that make the tech work. I realize you’re speaking without jargon for a general audience, but, say, merely finding some filter (or colored glass, say) having the same tint won’t reproduce the effect. It has to have the spectral filter function of ours. (Said differently, for any tint, there are infinitely many spectra that differ in how they modify colors, but still all have the same tint.)

(4) In our experience, the Oxy-Amp is not successful for hospital workers — perhaps because they’re more a hostage to interior lighting constraints, or are less the type that carries tool kits around with them — than paramedics, where we have had good results.

(5) Even though paramedics tend to do their procedures inside the truck, their initial encounter is usually outside the truck, and in daylight the Oxy-Amp makes all clinical signs easier to see, not just veins. Out hope is that paramedics have our Oxy-Amp tech as their sunwear, so they get the UV protection needed, but also clinical enhancement.

Thanks again.

Leadership’s Voice

A friend of mine shared an article from EMS Leadership Academy with his link preface saying:

Classic leadership advice: “Its not what you say; its what they think it means.” (sic)

You’re trying to get your message across. Something needs to change, and maybe the impetus for the change wasn’t something negative that happened as you hear everyone suspects. Maybe it was benign or you felt it was a good direction to go, but still, you’re getting pushback. Let me give you a nickel’s worth of free advice…

If they aren’t getting your message, saying it louder won’t change anything.

It’s not a hearing problem. It’s an interpretation problem. Maybe you should consider changing your delivery rather than getting frustrated with their interpretation.

Do you even realize?

You probably pay no mind to it…

We do it every day. We start our shift on the computer, running our checksheets, checking our e-mail, logging in to our ePCR programs to check for QA kickbacks and open charts. We get in the rig. You get assigned a post or a call and you look at the CAD and GPS. You check your smartphone or tablet for CAD info on the call you’re about to go in to. You might start prefilling the ePCR now. Your eyes leave the screen long enough to clear intersections.

You’ve on scene and you’ve made patient contact. You’re back to the screen entering demographics, meds, allergies, vital signs. You move to the box with your patient. All your tech is coming together to form a mural of diagnostics on your patient and it too goes into the ePCR. You make it to the ER and now you have to finish your documentation with your final vitals, handoff report, diagnostics, and what have you. You’re back in the rig and at it all over again.

Maybe you’re lucky enough to have a few minutes to rest, so you pull out your phone and check your texts and Facebook. There’s that viral game everyone is playing and you’ve dropped a bit on the leaderboard, so you pop over to the game and play for just a couple minutes before you get back to charting or working on that online CE due by the end of today. Maybe you’ve got more time and a station. A cushy recliner to fall back into has your name on it, and you need to decompress so you watch a movie with the crew.

Do you even realize?

You’re now spending virtually every waking minute of your day in front of one display screen or another. Do you know what it is you have been unwittingly doing to yourself? Do you realize why you have that mild, nagging headache? Do you realize why you keep rubbing your eyes? You aren’t tired yet. You haven’t felt the need to grab an energy drink. So what could it be?

What you are unwittingly doing to yourself is constantly barraging yourself with artificial blue light (1). Every computer screen, smartphone, tablet, and television we encounter now emits this artificial blue light. It has been linked to sleep disorders by interfering with our Circadian rhythms, and it affects our blink rates, giving us dry eyes, and it even gives us headaches.

Sleep in public safety is precious enough. Need we discuss how many accidents and medical errors are attributed to sleep deprivation? It’s a well-known fact. Dry eyes due to less blinking can cause corneal scarring and abrasions, loss of visual acuity, and even ulcerations (2). There are many things that contribute to headaches, including medications, fatigue, stress, sleep apnea, and eye strain.  Some studies suggest night owls exposure to light contributes to cancer, diabetes, and even more health disorders and recommended wearing blue light blocking eyewear (3).  Emergency Services personnel work around direct blue lights regularly when we are responding to and on scene of emergency calls.

What can you do about it?

Many of us wear corrective lenses now, yours truly no longer being an exception to this. I worked for a blood bank for a year near the beginning of my EMS career and that was where I had my first blood exposure. From that moment on, I vowed to wear some kind of lenses in front of my eyes. I always wore clear lenses, even though I didn’t need them to be corrective. The problem is typical lenses don’t do anything about light outside the non-visible UV spectrum.

Recently, I came across a brand of glasses called “Gunnar”. I found them at the annual CES event in Las Vegas about three years ago, and I tried them out. I found them to be extremely comfortable and after a couple minutes, felt like my eyes weren’t working so hard to focus on the computer displays in their booth.

Gunnar Phenom - Amber Tint

Gunnar Phenom – Amber Tint

Fast forward to the present and I’ve decided to give Gunnars a good long look (pun intended). I work in front of computers constantly in my full-time healthcare IT job where I have a wall of big screen monitors watching the health of hundreds of computer systems and I have three monitors on my desk, and when I’m not there, I’m studying to complete my degree online, I’m frequently on my smartphone, or I’m watching my LCD TV’s, or I’m reading a book on my tablet. On the ambulance, I’m blessed with a somewhat inefficient ePCR system and it isn’t unusual to take an hour or more to fill in a chart and check off all the special little boxes that are required to keep me out of PCR jail.

I’ve gotten out of the habit of turning my screen brightness to max when I can avoid it, and I try to get away from the tech for at least a half hour before bed, but I’m finding I still have headaches quite frequently. I’ll be due for some new eyeware soon under my insurance plan, so I’ll get my own prescription Gunnars then. A coworker of mine has a prescription set and he really enjoys them. They look sharp, are minimal in design, and are even becoming a favorite amongst gamers.

Gunnar has a couple lens tints, including sunglasses, regular clear (they call them “crystalline”), and amber. For what we do in public safety and patient care, I wouldn’t recommend the amber tint lenses, as they will shift color perception, which we depend on to assess a patient’s skin color (think cyanosis, pale, and even jaundice), so I’d stick with the crystalline lenses and the sunglass tints.

Remember, you don’t need a corrective lens prescription to wear these. The most common use of Gunnars is non-prescription. Prescription frames and lenses are available though. A nice feature about Gunnars is that they coat both the outside AND the inside of the lenses with an anti-reflective coating. Personally, I can attest to how annoying it is to have an anti-reflective coating on the outside, only to have a little light cause eye reflection on the inside (where you see your own eye refracting light onto the lens and creating distractions from your view).

They’re reasonably priced, especially given that they completely block the blue light wavelengths from all the assorted displays we spend our days and nights in front of. They also offer a wide range of styles so you can pick what’s best for your face and style. Check them out at www.gunnar.com. On their site, you’ll find a few different pages describing the benefits of each type of frame and lens, and a “How Do They Work” page as well.

Dislaimer:

I do not own a pair of Gunnars, yet. They are going to be my next prescription eyewear purchase due to the research I have done and due to trying a demo set on and wearing them for a bit to get a feel for them. I believe they are the genuine article and not a gimmick, so much so that I applied to be a brand ambassador for them and was accepted. This status with Gunnar thus far has resulted in me getting a free Gunnar t-shirt and nothing else, so really, I haven’t been incentivized to write this article, as I already have plenty of t-shirts… especially from EMS product and service vendors. 😉

Check out the references I used to compile this article below. If you have any experience with Gunnars, please drop me a comment and let me know what you think of them. Thanks for reading!

When “FREE” isn’t…

I like free as much as the next guy. In fact, I count on it to provide reviews on new tech for public safety here for you to read about.  What I don’t like is false advertising, like when you are given a code to redeem for a “free” product (in this case, a Bluetooth tracker for your keys, purse, or whatever you want to attach it to) and you sign up on the site and are told you’ll get an e-mail with instructions on how to complete the offer redemption.  Now they have the code, probably specially generated for the event or marketing campaign which is fine and probably a smart business decision to track marketing effectiveness, and they also have your e-mail address. Then they send you the “offer” to complete, and it takes you back to their site. The product is free, and suddenly, you see “+ S&H“. REALLY? You didn’t think to mention that when I visited your vendor booth at CES and talked with the rep for 10 minutes about your product, or to put that slightly totally relevant information on the “free” offer card, or on the special website page you dedicated to it BEFORE I submitted my e-mail address? You had to wait until the page where you paroxysmally ask for credit card information?

Too bad! I was really looking forward to writing a review article here to share with the public safety community. Wouldn’t a relatively inexpensive product like that be useful for preventing crews from leaving jump bags and $25,000 monitor/defibrillators, or portable ultrasounds, or laptops and tablets, or apparatus and narc cabinet keys on scene?

I’d love to publicly shame the company that opted to use this disappointing tactic on its guests and potential customers, but I apparently have more integrity than they do, and I don’t post negative reviews.
