ABSTRACT:
An apparatus for controlled regulation of respiration depending on heart rate, in which the inspiration phase has a duration corresponding to a first multiple of the heartbeat period and the expiration phase has a duration corresponding to a second multiple of the heartbeat period, comprises a unit for heartbeat detection (14), a calculation unit (12) for processing data relative to heartbeat depending on external parameters and producing output signals which are a function of said multiples and external parameters, and signalling means (15) adapted to constitute a guide for the inspiration and expiration phases, piloted by said output signals. The apparatus may further comprise a respiration detecting unit (19), connected to the calculation unit (12) for comparison between the real respiration and theoretical respiration calculated by the calculation unit (12).
