# Pulse Oximetry

Pulse oximetry is a non-invasive method used to measure the oxygen saturation level in the blood. It provides a quick assessment of a person's respiratory status.

**What is Pulse Oximetry?**

## Using a Pulse Oximeter

1. Attach the Device: Place the sensor on a fingertip, earlobe, or toe.
2. Turn On the Device: Wait for the device to display the oxygen saturation level (SpO2) and pulse rate.
3. Interpret the Results: Normal SpO2 levels are typically between 95-100%. Levels below 90% indicate hypoxemia and require medical attention.
