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.RESPIRATORY DEVICE MEASURING SYSTEM. A gas distribution system (12) comprising a pressure generator (14), a pressure sensor (21), a control valve (20), and a processor (32). The pressure generator (14) pressurizes breathable gas (22) for delivery to a patient. The pressure sensor (21) measures a pressure difference between pressurized breathable gas (22) and atmospheric pressure. The control valve (20) is disposed downstream of the pressure generator (14) and is constructed and arranged to control a flow rate of pressurized breathable gas (22). Processor (32) controls the control valve (20) to bring the flow rate of pressurized breathing gas (22) to substantially zero while the pressure generator (14) is operating and, when the flow rate is substantially zero, determines at least one of atmospheric pressure, an atmospheric air density, or a density correction factor based at least in part on the pressure difference between pressurized breathable gas (22) and atmospheric pressure.
