Abstract

L'invention concerne un réglage automatique courant de la durée d'un cycle d'une phase d'inspiration ventilatoire, lors d'une ventilation assistée, en conformité avec le débit respiratoire d'un patient. Des signaux électriques sont générés, qui correspondent à la circulation des gaz échangés entre le patient et le ventilateur (écoulement) et/ou à la pression des voies aériennes (P¿aw?), et le débit respiratoire réel du patient (RR du patient) est déterminé sur une base continue, à partir de l'écoulement et/ou de la P¿aw?. La durée de cycle moyenne courante des efforts respiratoires (T<SB>TOT</SB> courant du patient) est estimée à partir du RR du patient. Une durée courante souhaitable de la phase d'inspiration (T<SB>I</SB> souhaitable) est calculée à partir du résultat du T<SB>TOT</SB> courant du patient, un ratio T<SB>I</SB>/T<SB>TOT</SB> choisi dans la plage physiologique généralement comprise entre 0,25 et 0,50. La fin de la phase de ventilation est provoquée, en conformité avec la T<SB>I</SB> souhaitable.
