Title (EN) METHOD FOR CARRYING OUT HEMODYNAMIC MEASUREMENTS ON A PATIENT AND FLOW-DIRECTED BALLOON CATHETER USED FOR THIS
(FR) PROCEDE PERMETTANT D'EFFECTUER DES MESURES HEMODYNAMIQUES SUR UN PATIENT ET CATHETER A BALLON A ECOULEMENT DIRIGE UTILISE A CET EFFET
Abstract:
(EN) A method for carrying out hemodynamic measurements on a patient, using a flow-directed balloon catheter (1) which is connected to a measuring unit and is at least provided with a distal measuring lumen (15) and a balloon-inflating lumen (16), comprising the steps of inserting the catheter by way of a suitable vein and further by way of the right atrium and ventricle into the pulmonary artery until the distal end with the inflated balloon in wedge position is stuck in a branch thereof and closes off the latter. A proximal measuring lumen (18) is provided a few centimetres apart from the distal measuring lumen (15). Then the pulmonary arterial pressure (PAP) is measured, as long as the catheter has not yet arrived in the wedge position, via both the proximal and distal measuring lumina and the two relevant, virtually identical pressure curves are simultaneously recorded. In the wedge position of the catheter with the balloon inflated, the pulmonary arterial pressure (PAP) and the pulmonary capillary wedge pressure (PCWP) via both said measuring lumina are measured respectively.
(FR) Procédé permettant d'effectuer des mesures hémodynamiques sur un patient , grâce à un cathéter (1) à ballon à écoulement dirigé connecté à un appareil de mesure, doté au moins d'un passage (15) de mesure distal et d'un passage (16) de gonflage du ballon, comprenant les étapes d'introduction du cathéter, au moyen d'une veine appropriée et en outre au moyen de l'oreillette et du ventricule droits, dans l'artère pulmonaire jusqu'à ce que l'extrémité distale, avec le ballon gonflé en position calée, soit enfoncée dans une ramification de celle-ci et obture ladite ramification. Un passage (18) de mesure proximal est ménagé à quelques centimètres du passage (15) de mesure distal. Ensuite on mesure la pression artérielle pulmonaire (PAP), tant que le cathéter ne se trouve pas dans la position calée, à la fois par le passage de mesure distal et le passage de mesure proximal, et les deux courbes de pression sensiblement identiques qui s'y rapportent sont simultanément enregistrées. Dans la position calée du cathéter avec le ballon gonflé, la pression artérielle pulmonaire (PAP) et la pression en position calée du capillaire pulmonaire (PCWP) par l'intermédiaire desdits passages de mesure sont mesurées respectivement.
