What Is a Pulse Oximeter?

A pulse oximeter is a medical device that measures the oxygen saturation levels in your blood, also referred to as SpO₂. It operates by shining light through a relatively transparent part of the body, typically a finger, earlobe, or toe and measuring the amount of light absorbed by the blood vessels. This information helps determine how well oxygen is being transported throughout the body.

SpO₂ levels typically range from 95% to 100% in healthy individuals. Readings below this range may indicate that there is insufficient oxygen in the blood, which could lead to serious medical complications. A pulse oximeter monitor is an essential tool for healthcare professionals and patients to track oxygen levels in conditions like COPD, asthma, sleep apnea, and cardiac diseases.

How Does a Pulse Oximeter Work?

The functionality of a pulse oximeter is based on light absorption and infrared technology. The device shines two wavelengths of light (red and infrared) through a thin body part, usually a fingertip or earlobe. These two wavelengths are absorbed differently by oxygenated and deoxygenated hemoglobin in the blood, and the device detects the amount of light that passes through to calculate the SpO₂ levels.

Light Absorption & Infrared Technology

The principle of operation revolves around the absorption of light. Oxygenated hemoglobin absorbs infrared light at different rates compared to deoxygenated hemoglobin. By analyzing the amount of light absorbed at both wavelengths, the pulse oximeter determines the oxygen saturation level in the blood.

Pulse Rate Detection

Besides measuring oxygen levels, pulse oximeters also detect pulse rate. The device calculates the number of heartbeats per minute by tracking the pulsations of blood in the finger, earlobe, or other measurement sites.

Oxygen Saturation (SpO₂) Measurement

Once the device has collected the light absorption data, it calculates and displays the oxygen saturation level, or SpO₂, on the screen, helping users understand how much oxygen is circulating in their blood.

Types of Pulse Oximeters

Different types of pulse oximeters are available, each designed for specific medical or personal needs. Below are the common types:
