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.</span>}, number={3}, journal={Vietnam Journal of Science and Technology}, author={Ronan, Le Page and Vinh, Nguyen Quang and Jean-Marc, Goujon and Luiz, Poffo and Monique, Thual}, year={2020}, month={May}, pages={328–343} }
