Your blood oxygen level is a key indicator of your overall wellness. It can help you understand how well your body is absorbing oxygen, and the amount of oxygen delivered to your body. The remarkable new sensor and app in Apple Watch Series 6 allow you to take on-demand readings of your blood oxygen as well as background readings, day and night.
Green, red, and infrared LEDs shine light onto the blood vessels in your wrist, and photodiodes measure the amount of light reflected back. Advanced algorithms then calculate the color of your blood, which indicates the amount of oxygen present.
