The Pixel Watch previously didn’t have the SpO2 tracking feature
Oxygen saturation is a measure of oxygen that red blood cells carry through the body relative to the red blood cells that do not carry oxygen. The human body needs a certain level of oxygen in the blood to function properly and efficiently. It is displayed as a percentage level and anything above 92 percent is considered normal.
The Pixel Watch’s blood oxygen sensor finally put to good use
Some Reddit users say that a new “Oxygen saturation” card has appeared below the Sleep score in their Pixel Watch’s Fitbit Today app. It shows a percentage for the “Last sleep session.” Tapping on it explains what the score means.
The rollout appears to be slow, which explains why a very small number of people have received the functionality. Regardless, it’s great news for Pixel Watch owners.
Blood oxygen saturation levels can help assess sleep quality and detect issues like sleep apnea. During waking hours, it could sniff out possible respiratory issues.
