Abstract

"MéTODO E APARELHO PARA DETERMINAR DéBITO CARDìACO". Um método e um aparelho para uso na determinação de débito cardíaco. O método inclui medir, quantitativamente, o fluxo de ar do paciente, via um sistema de medida de fluxo de paciente (32), um primeiro parâmetro indicativo do percentual de oxigênio inalado e exalado pelo paciente, via um sistema analisador de oxigênio (34), e um segundo parâmetro indicativo da concentração de oxigênio arterial do paciente via o sistema (58). O método também inclui induzir uma variação na concentração de oxigênio arterial do paciente, enquanto tirando outras medidas para monitorar os efeitos da variação na concentração de oxigênio arterial do paciente. O débito cardíaco é determinado por um sistema de determinação de débito cardíaco (36), dos dados coletados relativos aos efeitos da variação na concentração de oxigênio arterial do paciente.
