Beware of health sensors on mobile devices



[ad_1]

Today, digital electronics has become very small and now we have mobile phones that are real computers, many times dozens of times better than desktop computers. And that's probably the reason why a high quality phone can cost more or more of a fully equipped laptop or desktop. Finally, we have at least the same power as our computers, but in much smaller areas, of course, it costs money and much.

But with mobile phones, in the end, health bands, who use a series of sensors, have come to try to measure the vital signs of those who carry them. Thus, practically every health belt, including the cheapest in the market (Chinese), can measure pulse and sometimes blood pressure. This would supposedly enable those who have a group of these on the wrist to know whether their pulse is no faster than normal or that their blood pressure is adequate and whether the measurements are out of "normal" range, because you might think you should go to your doctor or to go to emergency, so as not to miss a possible health crisis.

Mobile phones are often the right computers behind health bands, which are nothing more than the "stupid terminals" that measure and transmit the app on the phone to display results, graphics and so on. And I'm obviously sure that more than one company already works on a device that eliminates the phone and that the health belt is all that's needed.

Apple watches, for example, have a number of health sensors that can measure many things, and according to the information we have, applications that measure our vital signs or our method of exercise are confirmed by companies that They are committed to the health of people at a professional level. However, we should warn about what these sensors are doing.

All measurements in a person's body, for example, in a hospital, are made with life-sustaining equipment, i.e. They are systems that have much greater quality control than what is in the bands of health or post-modern watches. These life-sustaining devices have passed a series of controls to be able to establish themselves as reliable measuring devices. And that's exactly what's suffering from many health bands or smart watches. Yes, it sounds nice to see how Apple's clock shows us on the phone's screened electrocardiogram of our heart, but from there doctors take the information as it is, something that is probably not happening.

It should be noted that not only medicine possesses measuring devices for life-sustaining (which makes them more expensive), but in other activities there are measuring devices that are fundamental for accurate belief that their measurements help to avoid any problem. false data. For example, in the dive there are consoles located on the diver's hand and that can measure the speed at which a diver must rise to the surface to get out of the water without the problem of excessive nitrogen in the blood that can be solved only in the hyperbaric chamber. And these devices are very important because it depends on them that the divers leave the sea safer and healthier, but they can also collapse. In fact, one of my brothers is a professional diver and his console has not been able to upgrade. My brother noticed something strange and decided to ignore what the device said and went to his learned procedures and left the water without any problems. The console is reported to the manufacturer, and even my brother recorded the same screen on which the error is displayed.

So, trust in technology is something we all do well, but we believe that the device can measure our vital signs and take the information with confidence that they are adequate, especially in equipment that is not life support. This is not the best idea. Let's say that all these sensors are interesting, entertaining, and even an argument for the sale of our technologically expensive toys, but trust in our lives is not a good idea at best.
