pulse oximetry

Pulse oximetry is a non-invasive method to measure how well your blood is carrying oxygen. It uses a small device called a pulse oximeter, usually clipped onto your fingertip, to shine light through your skin. The device detects how much light is absorbed by oxygen-rich and oxygen-poor blood, calculating your oxygen saturation level. This measurement helps healthcare providers monitor your respiratory health, identify potential oxygen shortages, and assess your overall oxygenation status quickly and comfortably without blood draws.
