1. A method of determining an individual'"'"'s respiration pattern, respiration rate, other cardio-respiratory parameters or variations thereof, the method comprisingsensinga) mechanical movements of the individual'"'"'s chest;
- and/orb) acoustic waves generated by the individual'"'"'s heart beats;
processing said mechanical movements and/or acoustic waves to obtain one or more respiration-dependent parameters for subsequent computational analysis of the individual'"'"'s cardio-respiratory parameters, whereinone respiration-dependent parameter is a variation in S1-S2 intervals between two consecutive heart beats and another respiration-dependent parameter is a variation in heart sound amplitude.
