Technologies in Health - Oximeter Module (spO2 monitor)

Introduction

Oximeter Module (spO2 Monitor) is a medical instrument used for monitoring of oxygen saturation in the blood. Continuous blood oxygen monitoring is essential in critically ill patients in ICU as well as in other patients with cardio-respiratory complications. Due to its non-invasive mode of working, this module can be safely used on patients without causing any harm or discomfort. The principle is based on the light (Red & Infrared) absorbtion property of blood. The monitor gives relative concentration of oxygenated hemoglobin and total hemoglobin (oxygenated & deoxygenated) to yield the oxygen saturation percentage of the blood. This module can be integrated with available Patient Monitors or can be used as a stand alone instrument with a microcontroller and a display unit.
