Abstract

CONJUNTO SENSOR VENOSO CENTRAL E MéTODO PARA DETERMINAR O RENDIMENTO CARDìACO DE UM PACIENTE. O conjunto sensor venoso central (11) compreende um corpo de cateter (2) com diversos orifícios proximais (3a, 3b, 3c) . A porção de cateter é inserida na veia cava superior (4) e inclui uma unidade de medição de fluxo proximal (6), e a porção de cateter é inserida na veia cava inferior (5) e inclui uma unidade de medição de fluxo distal (7) . O primeiro canal de entrada (8) supre um sinal de medição indicativo do fluxo v~ p~ para unidade de avaliação (10), com qual sinal a unidade de avaliação (10) calcula o fluxo de sangue na veia cava superior (4) Similarmente, um segundo canal de entrada (9> supre um sinal de medição indicativo de fluxo vd para unidade de avaliação (10), com qual sinal a unidade de avaliação (10) calcula a taxa de fluxo de sangue na veia cava inferior (5> . Pela lei da continuidade, a soma das taxas de fluxo nas veias cavas superior e inferior (4 e 5) corresponde à taxa de fluxo que passa através do coração direito (11) e artéria pulmonar (12), portanto, corresponde ao rendimento cardíaco.
