Abstract : The objective of the present study is to extract new information from complex signals generated by Respiratory Inductive Plethysmography RIP. This indirect cardio-respiratory CR measure is a well-known wearable solution. The authors applied time-scale analysis to estimate cardiac activity from thoracic volume variations, witnesses of CR interactions. Calibrated RIP signals gathered from 4 healthy volunteers in resting conditions are processed by Ensemble Empirical Mode Decomposition to extract cardiac volume signals and estimate stroke volumes. Averaged values of these stroke volumes SVRIP are compared with averaged values of stroke volumes determined simultaneously by electrical impedance cardiography SVICG. There is a satisfactory correlation between SVRIP and SVICG r=0.76, p
