The Blood Oxygen Sensor on Apple Watch Ultra: How Does It Operate?
Along with the other health sensors that rest on your wrist, the new SpO2 sensor is integrated into the back of the Apple Watch, as one might anticipate. Four clusters of red, green, and infrared LED lights are used to measure your levels; they interact with four photodiodes to convert light into an electrical current. Your wrist’s blood vessels are illuminated, and photodiodes measure how much light reflects back.
Your blood’s hue can assist identify how much oxygen is present in it. Blood that has enough oxygen is bright red, while blood that has insufficient oxygen is typically dark red. Your lungs may not be supplying enough oxygen if your blood is deficient in it. Call your doctor and ask questions if you have any concerns about the readings from your Apple Watch Ultra.
