This invention is a medical device for triggering the inflation of a pulmonary artery catheter balloon (22). The device generally comprises a wave form analysis machine (11) that monitors the pulmonary artery blood pressure wave form, and triggers the inflation of the catheter balloon (22) at such a time as to cause occlusion of the pulmonary artery during the systolic upstroke. The time of occlusion is then readily apparent in the resulting decaying blood pressure wave form, which then may be used as a basis for compartment model estimation of the pulmonary capillary pressure.

La présente invention concerne un dispositif médical permettant de déclencher le gonflement d'un ballonnet (22) de cathéter introduit dans une artère pulmonaire. Le dispositif comporte généralement un appareil (11) d'analyse de formes d'ondes qui contrôle la forme d'onde de la pression sanguine de l'artère pulmonaire et déclenche le gonflement du ballonnet (22) du cathéter à un moment précis, en vue de provoquer l'occlusion de l'artère pulmonaire pendant la phase systolique ascendante. La période correspondant à l'occlusion apparaît tout de suite dans la forme d'onde décroissante de la pression sanguine qui est obtenue sur l'appareil (11). Par la suite, on peut utiliser cette forme d'onde comme une base permettant l'évaluation des modèles compartimentaux de la pression capillaire pulmonaire.
