Apple yesterday announced the Apple Watch Series 6 with a new sensor that enables blood oxygen monitoring capabilities, but Apple did not clarify which countries the feature would be available in.

Some health capabilities, like ECG and irregular heart rate notifications, have been limited in availability because of regulatory requirements, but it appears that those requirements don’t 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 there are no health-related regulatory issues that Apple has to overcome. A support document on using blood oxygen monitoring does mention that it’s only available in “certain countries and regions,” however, so there may be some omissions.
Those who are interested in purchasing an Apple Watch Series 6 specifically for the feature should double check the availability page to make sure blood oxygen monitoring is supported in their country.
Measuring blood oxygen with the Apple Watch Series 6 is done through the new Blood Oxygen app. It uses a series of red and green LEDs and infrared light to measure the amount of light reflected by the skin, with advanced algorithms using this data to calculate the color of the blood to derive the blood oxygen level. Bright red blood has more oxygen, while darker red blood has less.
The Apple Watch Series 6 is available for purchase from Apple’s online store, with orders set to arrive starting this Friday.
