SpO2, also known as oxygen saturation, measures the percentage of oxygen your blood is carrying. It's a crucial indicator of how well your lungs are delivering oxygen to your bloodstream. A pulse oximeter, a small device that clips onto your finger, measures this oxygen saturation.
A normal SpO2 reading for a healthy individual typically falls between 95% and 100%. However, a reading below 95% can signal potential health issues, prompting a call to your healthcare provider.
The SpO2 level can be affected by various factors such as lung diseases, heart conditions, and even altitude. It's important to note that SpO2 is just one indicator of overall health, and a doctor should always be consulted for any concerns about SpO2 readings.
