What is pulsoxymeter?

A pulsoximeter is a medical device that is used to measure a person's oxygen saturation levels (SpO2) and pulse rate. It is a non-invasive device that is typically placed on the fingertip or earlobe. The device works by shining a light through the skin and measuring the amount of oxygen in the blood. The pulsoximeter then provides a numerical readout of the person's oxygen saturation level along with their pulse rate. This information is used by doctors and healthcare professionals to diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and respiratory infections. Pulsoximeters can also be used by individuals with certain health conditions to monitor their oxygen levels at home.
