What is SpO2 sensor?

An SpO2 sensor, also known as a pulse oximeter sensor, is a medical device accessory used to measure the oxygen saturation level (SpO2) in a patient’s blood. It is a crucial component of pulse oximeters, which are widely used in healthcare settings to monitor a patient’s respiratory status and oxygen supply.

The SpO2 sensor is typically a small clip or probe that is placed on the patient’s finger, toe, or earlobe. It consists of two light-emitting diodes (LEDs) that emit red and infrared light, and a photodetector that measures the amount of light absorbed by the blood.

The working principle of an SpO2 sensor is based on the different absorption characteristics of oxygenated and deoxygenated hemoglobin in the red and infrared light spectra. The sensor measures the ratio of these light absorptions, which is then used to calculate the percentage of hemoglobin in the blood that is saturated with oxygen (SpO2 level).

SpO2 sensors are designed to be lightweight, comfortable, and easy to use. They are typically reusable and can be connected to pulse oximeters via a cable or wireless technology. Some SpO2 sensors also incorporate additional features, such as motion artifact reduction or low perfusion performance, to improve measurement accuracy.

These sensors play a crucial role in various medical settings, including operating rooms, intensive care units, emergency departments, and during patient transport. They provide real-time information about a patient’s oxygenation status, allowing healthcare professionals to monitor and adjust oxygen therapy or take appropriate medical interventions when necessary.
