Abstract

MéTODO E SISTEMA DE CONTROLE DE VENTILAçãO PULMONAR MECáNICA. A presente invenção refere-se a um sistema de controle de ventilação pulmonar mecânica com banda de volume, mais particularmente a um sistema para administração de ciclos respiratórios em pacientes. Preferencialmente, ditos ciclos respiratórios sendo controlados por pressão, de forma que os volumes inspirados pelo paciente se mantenham dentro de uma banda de volume, compreendendo um limite de volume inferior e outro limite de volume superior, que são pré-determinados. Mais especificamente, o sistema de ventilação segundo a presente invenção permite que os volumes inspiratórios dos ciclos respiratórios controlados por pressão variem dentro de uma faixa pré-estabelecida, limitando o volume máximo e/ou aumentando o nivel de pressão de forma a manter os volumes recebidos pelo paciente acima de um volume minimo, preservando dessa maneira o padrão de variabilidade natural observado na respiração humana, ao mesmo tempo assegurando a administração de volumes dentro de limites pré estabelecidos.
