Abstract

MéTODOS PARA DETECçãO E/OU MEDIçãO DE COMPORTAMENTO DE FLUXO, PARA DETECçãO DE UM FLUXO PULSANTE DE UM FLUIDO DENTRO DE UM INDIVìDUO, E PARA DETECTAR SE HA UM FLUXO DE UM FLUIDO DENTRO DO CORPO DE UM INDIVìDUO QUE EXPERIMENTOU RECENTEMENTE FIBRILAçãO VENTRICULAR, E, SISTEMA PARA DETECçãO E/OU MEDIçãO DE COMPORTAMENTO DE FLUXO Um método e aparelho de ultra-som, para detecção e/ou medição de pulso e/ou fluxo de sangue de um indivíduo, calcula um espectro de sinal Doppler de um sinal de ultra-som retro-espalhado do sangue em uma artéria do indivíduo. Indícios do comportamento do fluxo são calculados para várias faixas de freqüência dentro do espectro de sinal Doppler e esses indícios podem ser usados para determinar a pulsação e/ou o fluxo de sangue, assim como outros parâmetros do comportamento do fluxo. Por causa da natureza robusta dos índices calculados, o método e aparelho de ultra-som tem um uso particular em um Desfibrilador Externo Automatizado ou Semi-Automatizado (AED) para determinar se deve desfibrilar um paciente.
