COMPARISON OF TWO METHODS FOR DEMODULATION OF PULSE SIGNALS – APPLICATION IN CASE OF CENTRAL SLEEP APNEA Nguyen Quang Vinh 1 , Le Page Ronan 1 , Goujon Jean-Marc 1 , Poffo Luiz 1 Thual Monique 1 1 UEB, Université Euro péenne de Breta gne, Enssat, France CNRS UMR 6082 FOTON, Enssa t, 6 rue de Kerampont, BP 80518, 22305 Lannion, France Corresponding author: [email protected] Received March 03, 2011; revised August 10, 2011; accepted September 07, 2011 ABSTRACT In the ﬁeld of 24/7 human health monitoring, pervasive computing makes possible the continuous analysis of physiological parameters from an ambulatory device with a great acceptability. This paper presents two methods for obtaining cardiac and respiratory rates from a single arterial pressure signal: AM-FM demodulation and Singular Spectrum Analysis (SSA). With the aim to monitor sleep apnea, two simulated central sleep apnea were performed and recorded with Biopac reference system. The results showed a good evaluation of the cardiac rate with Singular Spectrum Analysis and bad results with AM-FM demodulation. For the respiration rate, some other signals were tested with average results for both methods. Further experiments will deal with real sleep apnea cases and algorithm improvements. Keywords. Optical pulse signal, AM-FM demodulation, Singular Spectrum Analysis (SSA), Singular Value Decomposition (SVD), Principal or Independent Component Analysis (PCA or ICA), Heart and Respiratory Rates. 1. INTRODUCTION In the coming years, there will be a strong development of non invasive physiological devices for monitoring health conditions. Telecare and telemedicine are going to be more and more employed, especially in developed countries. In our case, we have designed a device comprised of an optical arterial pulse and mechanical sensors, worn at the wrist for a great acceptability, which can be used to monitor people conditions (mainly heart and respiratory rates). Our aim applications are physiological monitoring for elderly persons and sleep apnea detection. Central sleep apnea is a sleep disorder in which the brain doesn't send regular signals to breathe, causing the breathing to pause and restart repeatedly during sleep.
