Jan 14, 2022 · Cyanosis. If blood oxygen saturation levels fall to around 67%, Cyanosis will set it. The lack of oxygen being transported by your blood cells, causes a blue tinge to develop on your skin. Your mouth, lips, and beneath your fingernail matrix will be affected first, followed by the spread occurring over the rest of your body.
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.
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 ...
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.
Jan 13, 2023 · Pulse oximeters are most accurate when blood oxygen saturation is between 90% and 100%. 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% ...
Feb 24, 2022 · A pulse oximeter reading indicates how much oxygen is getting to your body through your bloodstream compared with the maximum amount it could carry. It is a basic indicator of health, similar to vital signs. A normal blood oxygen saturation level is in the range of 95–100%. If it falls below 91%, it requires immediate medical attention.

For most healthy folks at sea level, normal pulse oximeter readings are: Oxygen saturation (SpO2): 95-100%. Pulse rate: 60-100 beats per minute. Oxygen levels below 90% are considered low and may indicate a health issue. Between 90-95% is still normal for some groups, but repeat low numbers warrant a closer look.
