A smartwatch helps detect COVID 19 days before symptoms appear

Smartwatches and other wearable devices that continuously measure a user’s heart rate, skin temperature, and other physiological markers can help with discovery. Coronavirus infection A few days before the individual is diagnosed.

Devices like Apple watch, Garmin and Fitbit watches have been tested by the virus to see if individuals are COVID-19 positive even before symptoms appear, according to studies by major medical and academic institutions such as Mount Sinai Health System in New York and Stanford University. You can predict whether it can be detected with. In California. Experts say wearable technology can play an important role in stopping pandemics and other infectious diseases.

Subtle changes in heart rate

Researchers at Mount Sinai have discovered that the Apple Watch can detect subtle changes in an individual’s heart rate. This can indicate that an individual is infected with the coronavirus up to 7 days before the test makes them feel sick or detects the infection.

“Our goal was to use tools to identify the infection at the time of infection or before people realized they were ill,” said Warrior, an assistant professor of medicine at Mount Sinai School of Medicine in New York City. Watch author Rob Hilten said. Research.

Specifically, this study analyzed a metric called heart rate variability (time variation between heartbeats). It is also a measure of how well a person’s immune system is functioning.

“We already knew that heart rate variability markers would change when inflammation occurred in the body. Covid is a very inflammatory event,” Hirten told CBS Money Watch. “It makes it possible for people to predict that they are infected before they know it.”

Studies have shown that individuals with COVID-19 have less heart rate variability, that is, little time variability between heartbeats, as opposed to COVID-negative individuals.

High heart rate fluctuations do not reflect an increase in heart rate. This indicates that the individual’s nervous system is active, adaptable, and more resilient to stress.

Investigators tracked approximately 300 health care workers on Mount Sinai wearing Apple Watch between April 29 and September 29.

Apple didn’t participate in or fund the survey, but it knows how the watch works. In September Tim Cook promoted the role of watches in the study of Mount Sinai.

According to a model from the US Centers for Disease Control and Prevention released last week, given that more than half of coronavirus cases are spread by asymptomatic carriers, the data collected by smartwatches can be used to tame the virus. May be useful.

“For now, we rely on people who say they’re sick and sick, but wearing an Apple Watch allows us to identify asymptomatic people without the need for active user input. This is a better way to manage infections, “Hirten said.

Early alert

In another study at Stanford University, where participants wore various activity trackers from Garmin, Fitbit, Apple, and other manufacturers, 81% of coronavirus-positive participants had changes in resting heart rate up to nine and a half days ago. It turns out that I experienced the onset of symptoms. Extremely high heart rates indicated the onset of symptoms, the study reported.

According to a study published in Nature Biomedical Engineering in November, researchers used smartwatch data to identify nearly two-thirds of COVID-19 cases 4-7 days before people showed symptoms. The study examined data from 32 people who tested positive for the virus from a pool of more than 5,000 participants.

The team has also created an alert system that warns the wearer that their heart rate has risen for a period of time.

“The alarm is set with a certain sensitivity, so it sounds every two months,” said Michael Snyder, a professor at Stanford University who led the study. “Regular fluctuations do not trigger alarms. Only significant and persistent changes are triggered.”

“It’s a big problem because it warns people not to go out and meet people,” he added. For example, when Snyder’s alarm sounded recently, he canceled the face-to-face meeting in case it could be infectious.

Such techniques could also help make up for some of the shortcomings of coronavirus testing, Snyder said. “The problem is that people can’t always do that, but these devices measure you 24 hours a day, 7 days a week. Smartwatches return data instantly in real time, but if you’re lucky You can get your test back in a few days. “

Wearable device makers are also looking at ways to use this technology to fight viruses. Oura Health, which creates smart rings to track health data, funded research at the University of California, San Diego and the University of California, San Francisco, to detect subtle symptoms such as early onset of fever that may indicate COVID-19. I found that I could do it. ..

Whoop, a manufacturer of sleep tracking devices, has partnered with Australia’s Central Queensland University to show that its technology helps predict coronavirus infections based on deviations in the user’s respiratory rate during nighttime sleep. I wrote a treatise. Healthy individuals had little fluctuation in respiratory rate, but deviations suggested poor airway health.

“All these studies Physiological markers collected from the device allow non-invasive identification of these conditions and diseases, “Hirten said. “They all have their limits, but they complement each other.”
