Focus on asthma, heart failure and respiratory diseases ›Macerkopf

Apple is placing an ever increasing focus on fitness and health with the Apple Watch. Other functions become a minor matter. This also has today’s announcement of the Apple Watch 6 and Apple Watch SE shown. As part of today’s event, the Cupertino-based manufacturer has also announced three new “Apple Watch health studies”.

Apple is conducting three health studies

Apple has already carried out various health studies with the Apple Watch in recent years. Now there are three more studies.

Apple is working with researchers to conduct three health studies, including using the Apple Watch to investigate how oxygen levels in the blood can be used in future health applications. This year, Apple, in partnership with the University of California, Irvine and Anthem University, will explore how measurements of blood oxygen levels along the longitudinal axis of the body and other physiological signals can help treat and control asthma.

Regardless, Apple will work closely with researchers at the Ted Rogers Center for Heart Research and the Peter Munk Cardiac Center of the University Health Network, one of North America’s largest health research organizations, to better understand how measurements of blood oxygen levels and others know about the Readings obtained from Apple Watch can help treat heart failure. Finally, researchers from the Seattle Flu Study at the Brotman-Baty Institute for Precision Medicine and faculty members at the University of Washington School of Medicine will try to figure out how cues from apps on the Apple Watch, such as heart rate and blood oxygen levels, are early signs of respiratory illness like flu and COVID-19.

As a big innovation in the Apple Watch 6, Apple has announced a blood oxygen sensor and the corresponding app. With this, the user can easily measure the oxygen saturation of the blood and thus better assess his general fitness and well-being. Oxygen saturation, or SpO2, represents the percentage of oxygen-laden red blood cells that absorb the oxygen inhaled through the lungs and distribute it to the rest of the body. The value shows how well this oxygen-containing blood is transported throughout the body.

In order to compensate for the natural differences in the skin and improve accuracy, the sensor uses four clusters of green, red and infrared LEDs to measure the oxygen content in the blood, as well as the four photodiodes in the glass of the case back of the Apple Watch to reflect the light reflected back from the blood measure up. The Apple Watch then uses an advanced algorithm built into the Blood Oxygen App that measures the oxygen content in the blood in a range between 70 and 100 percent. The user can carry out on-demand measurements at any time when he is standing still and regular measurements take place in the background when the user is inactive, including sleep phases. All data is visible in the health app and the user can view trends to see how his blood oxygen content changes over time.
