Description

A pulse oximeter is a compact medical device designed to monitor the oxygen saturation of a patient’s blood and pulse rate non-invasively. It works using a light-emitting sensor that passes through a fingertip, earlobe, or toe to measure how much oxygen the red blood cells carry.

Pulse oximeters are essential tools in hospitals, physiotherapy clinics, and home care settings, especially for patients with respiratory conditions such as asthma, COPD, pneumonia, or heart disease.

Regular monitoring with a pulse oximeter helps detect hypoxia (low oxygen levels) early, enabling timely medical intervention.
