Objectives : Pulse photoplethysmography uses light absorbance technology to detect waves produced by heartbeats. This technique, is the basis for measuring SpO2 (1). The photoplethysmogram is one of the signals recorded during polysomnography. This signal can be considered as a good indicator of coronary pathology (2). It is easy to individualize amplitude variations of the photoplethysmographic signal in relation to events occurring during sleep (fig). We develop an algorithm and apply it (…)
