Brief summary
Acquisition of synchronized cardiovascular signals from non-invasive measurements (ECG, photoplethysmography pulse sensors, inductance plethysmography) in healthy volunteers aged from 18 to 75, during spontaneous ventilation with apneas (20 seconds) for a total acquisition time of 30 minutes.
Interventions
OTHERphysiological signal acquisitions
Subjects will be fitted with non-intrusive devices. In a semi-recumbent position, they will be asked to perform * 10 minutes of resting breathing * 10 cycles consisting of a 20-second apnea, to be performed at the end of inspiration, and 1 minute 40 of breathing (100 seconds). This single participation session will last a total of one hour for the volunteer (equipment, recording, de-equipping), including 30 minutes of acquisition.
