How to Read a Finger Pulse Oximeter and What Should You Know?

HEALTH CAPSULES LTD on Instagram: "A pulse oximeter uses light technology to measure how much oxygen your red blood cells are carrying, no needles and no blood drop needed. - It shines red and infrared light through your fingertip. - A sensor detects how much light passes through. - Because oxygen-rich and oxygen-poor blood absorb light differently, it calculates your oxygen saturation (SpO₂). - It also tracks tiny changes in blood volume with each heartbeat, that’s how it shows your pulse rate.
