The Apple Watch 10 proves itself as a medical device

The Apple Watch has long been the Bad Bad Leroy Brown of smartwatches (baddest man in the whole damned town). The new Series 10 – bigger, brighter, slimmer – maintains that status.

But it’s also increasingly clear that the future of the Apple Watch isn’t just as an alternative to cellphones but also as a medical device. And the Series 10 takes an already-impressive skillset in that regard and adds even more oomph under the hood.

The Apple Watch currently measures your heart rate, ECG, sleep, steps and other vitals. New to the Series 10 is gauging the likelihood of sleep apnea , a potentially serious disorder characterized by interrupted breathing while asleep.

All this data is conveniently aggregated in Apple’s Health app , which is quickly becoming the one-stop shop for personal health info.

Reportedly in the works for future versions of the Apple Watch: Blood pressure monitoring and blood glucose readings.

It’s important to emphasize that Apple can’t, by law, market the watch as a medical device. That would require regulatory approval from the Food and Drug Administration , not to mention a prescription from your doctor to get one.

The Apple Watch, therefore, is positioned as a handy way to oversee various aspects of daily activities but not as a way to treat medical conditions.

Even so, that’s precisely what some people are already doing.

People with Type 1 diabetes (such as myself) can connect their Dexcom blood-glucose sensor —an FDA-approved medical device—directly to their Apple Watch. This allows them to see their blood sugar in real-time, right on their wrist, and to act accordingly if they’re running high or low.

I can’t tell you what a big deal this is, instantly making the Apple Watch one of my most valuable tools in managing a chronic illness. I suspect blood pressure monitoring, when available in this country, will be no less game-changing for people with hypertension or stress issues.

As a long-time crappy sleeper, I’ve monitored my sleep patterns for months with my watch, but mostly all it’s told me is that I toss and turn a lot at night, which I already knew.

The new sleep apnea feature takes that up a level. It monitors overnight respiration and, at the end of 30 days, provides an assessment of your likelihood of needing treatment.

Again, the Apple Watch isn’t a card-carrying medical device, so the best it can do in this case is crunch the numbers and then advise you, if your numbers are high, to go see a doctor for proper testing.

Even so, I found it interesting and reassuring to see this data compiled. As I expected, the sleep apnea feature found that I’m not showing signs of the disorder (my wife probably would have told me if I was years ago), but it’s nice to check that particular box, health-wise.

I expect healthcare will be an increasingly important feature of the Apple Watch, and a good reason to wear one.

Yes, it’s nice seeing various notifications on your wrist and to have speedy access to favorite apps, but health maintenance provides a standout reason to add a smartwatch to your trove of electronic toys. And it’s a fair bet subsequent versions of the Apple Watch will build on this momentum.

It’s also not hard to envision a time when a premium version of the watch does have regulatory approval as a medical device and, with a doctor’s prescription, will play an indispensable role in managing all sorts of disorders in the same way that mine now handles diabetes.

For the time being, the Apple Watch Series 10, starting at a price of around $400, demonstrates that this gadget is no longer just a novelty or status symbol. It’s a genuine boon to healthcare.

Badder than old King Kong, you could say.
