Apple Watch's oxygen meter is as reliable as a medical device


When Apple released the Apple Watch series 6, it did in the middle of a pandemic. With a new sensor capable of measuring oxygen in blood. One of the serious symptoms of COVID-19 is a lack of oxygen. Many have wondered and analyzed the ability of this sensor in the watch, to determine its true value. The University of Sau Paulo, Brazil, has determined that it is as reliable as those used in hospitals.

The study from the University of Sao Paulo in Brazil, published in the journal Nature, pitted the Apple Watch Series 6 against a pair of commercial pulse oximeters. Approximately 100 patients from an outpatient pulmonology clinic with interstitial lung disease and chronic obstructive pulmonary disease (COPD) were studied with the devices. "Strong positive correlations" were seen between the Apple Watch and commercial oximeters to assess heart rate measurements and oximetry. While the Apple Watch tended to report higher oximetry numbers on average, the study «Did not observe significant differences»For both blood oxygen and heart rate figures.

Our results indicate that Apple Watch 6 is a reliable device to obtain heart rate and SPO2 in patients with lung diseases under controlled conditions. The advancement of smartwatch technology continues to improve and studies must be conducted to assess accuracy and reliability in various types of diseases.

One more step that puts the Apple Watch as one of the best devices that may currently be on the market. Taking into account that studies are being initiated in which the device can help detect neurological diseases such as dementia or depression. An almost medical device on our wrists. An impressive advance without a doubt.
