Smart watches are "IQ tax"? Those health monitoring functions can really save lives.

Mr. Shi from Shenzhen works out every day, but he can't sleep well. One night, he slept 1 hour and had 49 apnea, which was very serious. Severe apnea may lead to complications such as hypertension, coronary heart disease, diabetes, cerebrovascular disease, and even sudden death at night.

A few days later, he suddenly received a phone call from Beijing 30 1 Hospital, reminding him that he had high health risks and severe atrial fibrillation, and suggested seeking medical attention in time. Subsequently, Mr. Shi went to the hospital in time and had atrial fibrillation surgery and apnea correction. This is the story reported by Shenzhen Satellite TV at 30 noon on June 5438+065438+ 10 in 2020. It was the "hero" who discovered Mr. Shi's serious hidden danger, and it was the glory smart watch he wore on his wrist every day.

There are many life-saving stories about smart watches like this. Smart watches that not only have the appearance of fashion technology, but also provide health data such as exercise, sleep, heart rate and blood oxygen anytime and anywhere are in the strong demand of contemporary young people to pay attention to the changes of health indicators at all times. According to the latest data from Counterpoint, a well-known market research institution, in 20021year, the global smart watch market shipped 654.38+275 million pieces, up 24% year-on-year. Among them, Apple ranks first with a market share of 30%, and Samsung, Huawei, Huami and Xiaomi rank among the top eight in the world.

Under this trend, many technology giants such as Apple, Samsung, Huawei, Huami, Xiaomi and OPPO are constantly optimizing the health monitoring function of smart watches. These seemingly conceptual functions can really save lives at critical moments.

Heart rate monitoring

Apple Watch has been equipped with heart rate monitoring function earlier. Many users have been saved by wearing Apple Watch, and many media have reported it many times. For example, in April of 2065438+2008, Skylar Joslin, a student from Oklahoma, was at school, and his watch gave a warning of abnormal heart rate. Jocelyn had tachycardia before, so he sent this reminder to his mother by text message. Later, jocelyn's mother immediately took him to a nearby emergency room for treatment. It took jocelyn 7.5 hours to turn the corner.

Oxygen saturation detection

Oxygen saturation is the volume percentage of oxygenated hemoglobin in blood, which reflects the concentration of oxygen in blood. With the development of flexible electronics technology, the sensor based on PGG principle can monitor oxygen saturation without taking blood.

This function can be applied not only to the daily health monitoring of users, but also to the field of sports. It will provide a scientific sports monitoring system for athletes to track their physical condition at any time, which will become a breakthrough new technology in competitive sports and help athletes make new breakthroughs.

Fall detection

There are even more examples of fall detection. When the user falls, the watch will judge the user's state. If the user can't move, the watch will automatically alarm and transmit positioning information.

"Fall Detection" of Apple Watch

This function can provide potential protection for elderly users and users who love cycling and other sports. A young couple accidentally fell off a cliff while hiking in New Jersey. They thought they would die without help because of a broken bone. Unexpectedly, their watches automatically dialed 9 1 1 to help them call rescuers.

It is understood that Apple is launching a "crash detection" function for Apple Watch, similar to "fall detection", which will automatically detect whether the user has suffered a car accident and automatically alarm or notify emergency contacts. "Collision detection" needs to make a judgment in a shorter time, and the requirements for the algorithm may be higher.

In recent years, with the outbreak of digital and intelligent medical care, the integration of medical care and technology has become a new way out, attracting many technology giants to enter the big health track. Therefore, smart wearable devices that can supervise health management, including smart watches, are also in the limelight.
