Apple yesterday announced the Apple Watch Series 6 with a new sensor that enables blood oxygen monitoring. However, Apple has not clarified which countries the feature will be available in.
Some health features, such as EKG and irregular heart rate notifications, were limited in their availability due to legal requirements, but it appears that these requirements do not apply to the blood oxygen monitoring feature.
According to the Apple Watch Feature Availability page, blood oxygen monitoring is available in more than 100 countries, suggesting Apple doesn’t need to address health-related regulatory issues. However, a supporting document for the use of blood oxygen monitoring mentions that it is only available in “certain countries and regions” so there may be some omissions.
Those looking to purchase an Apple Watch Series 6 specifically for this feature should check the availability page to make sure that blood oxygen monitoring is supported in their country.
The measurement of blood oxygen with the Apple Watch Series 6 takes place via the new blood oxygen app. It uses a series of red and green LEDs and infrared light to measure the amount of light reflected from the skin. Advanced algorithms use this data to calculate the color of the blood and derive blood oxygen levels. Bright red blood has more oxygen while dark red blood has less.
The Apple Watch Series 6 is available from the Apple Online Store. Orders are expected to come in from Friday.
