Pulse Oximeter Readings Chart

Posted on

A pulse oximeter is a medical device that indirectly measures the oxygen saturation of arterial blood. The name "pulse oximeter" derives from its use to measure oxygen saturation by measuring the changes in pulsation amplitude (related to the strength of arterial blood flow) during each heartbeat.

An oximeter works by shining light through a portion of the body, typically a finger, earlobe or nostril, that is perfused with arterial blood. The "pulse" component of pulse oximetry refers to the pulsing nature of arterial blood flow. The light waves are passed through the tissue and detected by a photodetector on the other side. The amount of light absorbed by the tissue is proportional to the amount of oxygenated hemoglobin in the blood; therefore, by measuring the absorption of light at different wavelengths, an estimate of arterial oxygen saturation can be made.

A pulse oximeter reading chart can help you understand what your readings mean. The chart will list different saturation levels and what they mean in terms of your oxygen level. For example, a reading of 97% means that your oxygen level is normal. However, a reading of 90% means that your oxygen level is low and you may need supplemental oxygen. A reading of 80% or below indicates that you are in danger of respiratory failure and require immediate medical attention. 

Pulse oximetry is a simple, painless test that can give you important information about your oxygen level. If you have any questions about your readings, be sure to ask your doctor or nurse.

A pulse oximeter reading chart can help you understand your oxygen saturation levels and what they mean for your health. By understanding your readings, you can be proactive in ensuring that your oxygen level stays within a healthy range. If you have any questions about your pulse oximetry readings, be sure to ask your doctor or nurse for more information.
