Abstract
"SISTEMA DE ACIONAMENTO E MéTODO PARA CONTROLAR A COMPRESSãO CARDìACA". Esta invenção é um sistema de inflação (50) para controlar independentemente o perfil de pressão, ou seja, o tempo de subida e nível de plató de fluído alimentado a uma câmara inflável (18) por uma fonte de fluído (56) por meio de passagens de fluído (52, 54) levando a reguladores de pressão alta e baixa (58, 60), e tanques (62, 64) cujas saídas são controladas por válvulas (66, 68) para prover as pressões alta e baixa necessárias em tempos específicos para definir o perfil de pressão.
