Oxygen saturation is a measure of how much oxygen the blood is carrying as a percentage of the maximum amount it could carry. Normal oxygen saturation levels are typically 95% or higher. Pulse oximetry is important for patient care because it helps monitor blood oxygen levels.
This information can be used to adjust oxygen therapy, if necessary, and to monitor for signs of respiratory distress. In addition, pulse oximetry can be used to detect other medical conditions, such as heart disease and anemia. As a result, this simple test can provide valuable information for both patients and healthcare providers.
