DESCRIPTION

A pulse oximeter is a medical device used to measure the oxygen saturation level in a person's blood. It is a non-invasive device that typically clips onto a person's fingertip, although it can also be placed on other parts of the body, such as the earlobe or toe. The device uses light sensors to measure the amount of oxygen-carrying hemoglobin in the blood. It also provides a reading of the person's heart rate or pulse.

To use a pulse oximeter, you simply place your finger inside the device and wait for a few seconds. The device will then display the oxygen saturation level as a percentage, indicating how well oxygen is being transported throughout your body. A normal oxygen saturation level is typically above 95%.

Pulse oximeters are commonly used in medical settings, such as hospitals and clinics, but they are also available for home use. They can be useful for individuals with respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD), as well as for athletes monitoring their oxygen levels during exercise. Regular monitoring with a pulse oximeter can help identify potential issues with oxygen levels and assist in determining the need for medical intervention.
