Description
A pulse oximeter is a medical device that is used to measure the oxygen saturation levels (SpO2) in the blood. It is a small, portable device that can be attached to the fingertip, earlobe, or toe. The pulse oximeter uses a non-invasive method to measure oxygen levels by shining a light through the skin and into the blood vessels.
The device measures the amount of light absorbed by the oxygenated and deoxygenated blood, and then calculates the oxygen saturation level. The result is displayed as a percentage on a digital screen, along with the pulse rate.
Pulse oximeters are commonly used in hospitals, clinics, and home care settings to monitor the oxygen levels of patients with respiratory or cardiac conditions. They are also used by athletes to monitor their oxygen levels during training or at high altitudes.
Pulse oximeters are available in different types and models, including handheld, wrist-worn, and finger pulse oximeters. Some models have additional features such as data storage, alarms, and Bluetooth connectivity to transfer data to a smartphone or computer.
Overall, pulse oximeters are an essential tool for healthcare professionals and individuals who need to monitor their oxygen levels for medical or fitness purposes.
