Title
(EN) METHOD AND APPARATUS FOR THE CARDIOVASCULAR ASSESSMENT OF A SUBJECT IN NEED THEREOF
(FR) PROCÉDÉ ET APPAREIL D'ÉVALUATION CARDIOVASCULAIRE D'UN SUJET EN AYANT BESOIN
Abstract
(EN) The methodology presented herein predicts, among other things, whether the application of MV, and in particular of high driving pressure, might lead to the development of RV failure in ARDS. The methodology of the present invention is thus aim at providing protective MV strategies. In this sense, in the present invention, and by using the methodology described herein, we have demonstrated changes in PVM during breathing that are affected by the implemented driving pressure; specially, in a situation where alveoli mechanics are heterogeneous which leads to a not uniform distribution of the effect of pressure changes into the lung tissue. The results presented herein also warn about the necessity of implementing the method of the present invention, capable of providing high accuracy measurements techniques, for a better description of respiratory effects of respiration on PVM.
(FR) La méthodologie présentée dans la présente invention prévoit, entre autres, si l'application de MV, et en particulier de haute pression d'entraînement, pourrait conduire au développement d'une défaillance RV dans le SDRA. Ainsi, la visée de la méthodologie de la présente invention est de fournir des stratégies MV de protection. Dans ce sens, dans la présente invention, et en utilisant la méthodologie décrite ici, nous avons démontré des changements de PVM pendant la respiration qui sont affectés par la pression d'entraînement mise en oeuvre ; en particulier, dans une situation où la mécanique des alvéoles est hétérogène, ce qui conduit à une distribution non uniforme de l'effet de changements de pression dans le tissu pulmonaire. Les résultats présentés dans la description avertissent également à propos de la nécessité de mettre en oeuvre le procédé de la présente invention, capable de fournir des techniques de mesures de haute précision, pour une meilleure description des effets respiratoires de la respiration sur le PVM.
