Apple announced Apple Watch Series 6. It features a Blood Oxygen Sensor and app. That addition was an excellent decision on Apple’s part considering that it appears that a low blood oxygen level might have something to do with COVID-19.
“Apple Watch Series 6 completely redefines what a watch can do,” said Jeff Williams, Apple’s chief operating officer. “With powerful new features, including a Blood Oxygen sensor and app, Apple Watch becomes even more indispensable by providing further insight into overall well-being.”
The Blood Oxygen sensor compensates for natural variations in the skin and improves accuracy by employing four clusters of green, red, and infrared LEDs, along with four photodiodes on the back of the Apple Watch, to measure light reflected back from blood.
Apple Watch then uses an advanced custom algorithm built into the Blood Oxygen app, which is designed to measure blood oxygen between 70 percent and 100 percent. On-demand measurements can be taken while the users is still, and periodic background measurements occur when they are inactive, including during sleep. All data will be visible in the Health app, and the user will be able to track trends over time to see how their blood oxygen level changes.
A person’s blood oxygen level has important information not just related to COVID-19, but also to other health issues. Apple will be collaborating with the University of California, Irvine, and Anthem to examine how longitudinal measurements of blood oxygen and other physiological signals can help manage and control asthma.
In addition, Apple will work with the Ted Rogers Centre for Heart Research and the Peter Munk Cardiac Centre at the University Health Network to better understand how blood oxygen measurements and other Apple Watch metrics can help with management of heart failure.
Investigators with the Seattle Flu Study at the Brotman Baty Institute for Precision Medicine and faculty from the University of Washington School of Medicine will seek to learn how signals from apps on Apple Watch, such as Heart Rate and Blood Oxygen, could serve as early signs of respiratory conditions like influenza and COVID-19.
Apple Watch Series 6 (GPS) starts at $399 and Apple Watch Series 6 (GPS + Cellular) starts at $499.
