Abstract

DISPOSITIVO PARA DETERMINAR UM PARÂMETRO HEMODINÂMICO DE UM PACIENTE POR MEIO DE ANÁLISE DE PERFIL DE PULSAÇÃO. Por meio de um primeiro canal de entrada (1), um sinal de pressão medido arterialmente é lido continuamente. O sinal de pressão lido é temporariamente armazenado na memória, na memória de trabalho (RAM). A função p (t) é processada pela unidade de processamento central (CPU), para calcular o volume do coração/tempo PCCO e outros parâmetros hemodinâmicos a partir dele. O cálculo compreende as seguintes etapas: A resistência vascular sistêmica SVRk é calculada para o período de pulsação corrente. O volume da batida do coração SVk do período de pulsação corrente (da sístole) de um período de pulsação, de acordo com a seguinte equação: com a distensão Ck (p) = (MAP-CVP)k/[SVRk.<dp/dt>k] .f (MAP, pi). A diferença entre a pressão arterial média MAP e a pressão venosa central CVP, bem como a inclinação média da curva de pressão na diástole <dp/dt>, são redeterminados para o período de pulsação corrente. O volume do coração/tempo calculado no período de pulsação corrente resulta de PCCOk = SVk. HR. Portanto a recalibração contínua da resistência vascular sistêmica bem como da distensão ocorre, por meio de parâmetros obtidos a partir dos dados de medição de pressão continuamente determinados.
