Oximetry

Oximetry is a non-invasive method used to measure the oxygen levels in your blood. It typically involves a device called a pulse oximeter, which clips onto your finger, toe, or earlobe. The device uses light to estimate how much oxygen your red blood cells are carrying. This measurement helps doctors assess your respiratory and cardiovascular health, ensuring your body receives enough oxygen to function properly. It’s a quick, painless, and useful tool for monitoring oxygen status, especially for people with lung or heart conditions.
