Abstract

SISTEMA DE MEDIçãO DE DISPOSITIVO RESPIRATóRIO. Um sistema de distribuição de gás (12) compreendendo um gerador de pressão (14), um sensor de pressão (21), uma válvula de controle (20), e um processador (32) . O gerador de pressão (14) pressuriza gás respirável (22) para distribuição a um paciente. O sensor de pressão (21) mede uma diferença de pressão entre o gás respirável pressurizado (22) e pressão atmosférica. A válvula de controle (20) é disposta à jusante do gerador de pressão (14) e é construída e disposta para controlar uma taxa de fluxo do gás respirável pressurizado (22) . O processador (32) controla a válvula de controle (20) para trazer a taxa de fluxo do gás respirá- vel pressurizado (22) para substancialmente zero enquanto o gerador de pressão (14) está operando e, quando a taxa de fluxo for substancialmente zero, determina pelo menos um de pressão atmosférica, uma densidade de ar atmosférico, ou um fator de correção de densidade com base pelo menos em parte na diferença de pressão entre o gás respirável pressurizado (22) e a pressão atmosférica.
