Development of a photoplethysmography signal processing method for oxygen measurement concentration

Pulse oximetry is a well-known procedure used to measure the level of oxygen (oxygen saturation) in the blood. The measurement of oxygen saturation level is of highly significance in supervising a patient’s health condition. This is most commonly supervised by a normal pulse oximeter, which has been...

This paper presents a low cost method to measure the level of oxygen using Photoplethysmgraphy (PPG)-based technique.

The DC component of the signal primarily represents the absorption in the intensity of light source, ambient light, sensitivity of the detector, tissue bed, bone, venous blood, capillary blood, and non-pulsatile arterial blood. The AC component captures the pulsating arterial blood and is of our main interest. By capturing the required AC content from the PPG signal, we can then determine the oxygen saturation level by extracting relevant features. 2015 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/41581/1/41581.pdf application/pdf en http://irep.iium.edu.my/41581/4/41581_Development%20of%20a%20photoplethysmography_Scopus.pdf Ahmed, Waiz and Khan, Sheroz and Sidek, Khairul Azami (2015) Development of a photoplethysmography signal processing method for oxygen measurement concentration.
