Abstract

método para determinar pressão parcial de um componente gasoso e regulador de máscara de respiração para ocupante de aeronave. um método para determinar uma característica tal como pressão parcial ou percentagem de um componente gasoso em um primeiro fluxo de mistura de gás (32) em uma câmara de fluxo (30) onde flui alternadamente o dito primeiro fluxo de mistura de gás (32) e um segundo fluxo de mistura de gás (34) compreendendo as seguintes etapas: a) introduzir o primeiro fluxo de mistura de gás (32) em uma cãmara de detecção (40) quando o primeiro fluxo de mistura de gás (32) flui na câmara de fluxo (30), b) impedir a introdução de gás da câmara de fluxo (30) para cãmara de detecção (40) pelo menos quando o segundo fluxo de mistura de gás (34) flui para dentro da câmara de fluxo (30), c) detectar a dita característica do primeiro fluxo de mistura de gás (32) na câmara de detecção (40).
