Sep 13, 2024 · Most people have a normal resting pulse oximetry reading for oxygen saturation (SpO2) between 95% and 100%. This shows that your blood has an appropriate amount of oxygen. People at higher altitudes may have slightly lower readings. If your oxygen saturation level drops below 95%, it may suggest a potential issue with your lung or heart function.
Apr 29, 2024 · Read the results. The pulse oximeter will display the results on its screen. The oxygen saturation level appears as a percentage (%), and the pulse rate as beats per minute (BPM). To verify whether a reading is correct, check the pulse waveform. The waveform is the moving wave on the screen that indicates the pulse.
Jun 13, 2024 · A normal range for your blood oxygen level is between 92% and 100%. SpO2 readings can fluctuate based on activity, overall health, and other factors. Your body relies on a coordinated effort between your heart, lungs, and circulatory system to maintain a healthy blood oxygen level. Without an adequate amount of oxygen in your blood, you can ...
Jan 13, 2023 · Accuracy decreases when blood oxygen saturation is between 80% and 90%, and the devices are least accurate when saturation is below 80%. Keep in mind that readings may be off by a few percentage points. For example, if an FDA-cleared pulse oximeter reads 90%, then the actual oxygen saturation in the blood is generally between 86% and 94%.
Jun 24, 2024 · If a U.S. Food and Drug Administration (FDA)-approved pulse oximeter reads 90%, then the actual oxygen saturation in the blood is approximately between 86% and 94%. [3] US Food and Drug Administration. Pulse Oximeter Accuracy and Limitations: FDA Safety Communication. Feb. 19, 2021.
