Your blood oxygen level (or oxygen saturation) is a crucial measure of your overall well-being. This level can help you understand how your body absorbs oxygen and evaluate the volume of oxygen it receives. The Apple Watch Series 6 features a new tool comprised of a sensor and app that allows you to check your blood oxygen level at any time, or activate measurements that run in the background, day or night. New Sensor. New Insights. The new blood oxygen sensor consists of four sets of LEDs and four photodiodes. Integrated into the entirely redesigned crystal back of the Apple Watch, it works with the Blood Oxygen app to determine your blood's oxygen level. Simply bright. Green, red, and infrared LEDs project light onto your wrist's blood vessels while photodiodes measure the amount of reflected light. Advanced algorithms then calculate the exact color of your blood, indicating the volume of oxygen present. ECG App: Get an ECG when you want, where you want. The Apple Watch Series 6 can generate an ECG (Electrocardiogram) equivalent to a single-lead ECG, a significant feat for a wearable device, allowing crucial data to be shared with your doctor and offering unparalleled peace of mind.
