What is an SpO2 Sensor? APK SpO2 Sensor Selection Guide
2025-10-17
Blood oxygen saturation is a key vital sign for assessing human respiratory and circulatory functions as well as oxygen delivery efficiency. APK Patient Monitor Accessories & Consumables-SpO2 Monitoring Series products, based on advanced photoelectric sensing technology, provide comprehensive, accurate, and reliable solutions for clinical settings—from daily screenings to critical care—ensuring patient oxygen safety at all times.
What is an SpO2 sensor?
An oxygen sensor, commonly known as an SpO2 sensor, is the core component of non-invasive blood oxygen monitoring. Its working principle is based on pulse oximetry: the sensor emits red and infrared light of specific wavelengths from one side, which passes through human tissue (such as a fingertip or earlobe) and is captured by a receiver on the other side. Oxygenated hemoglobin and deoxygenated hemoglobin in the blood absorb these two types of light differently. By analyzing the changes in light signals synchronized with the pulse, the blood oxygen saturation and pulse rate can be calculated.
