Abstract

LA INVENCION SE REFIERE A UN APARATO DE RESPIRACION CON UN FLUJO DE GAS EN BYPASS Y EN CADA UNA DE LAS CONDUCCIONES DE INSPIRACION (6) Y EXPIRACION (9) UNA VALVULA PARA EL AJUSTE DEL FLUJO DE GAS A TRAVES DE ESTAS CONDUCCIONES. UN MONTAJE DE CONTROL (20) ACTIVA LA VALVULA DE FORMA QUE SE GENERA UN CICLO RESPIRATORIO Y DURANTE LA EXPIRACION EL FLUJO DE GAS EN BYPASS SE MANTIENE. LA PRESION DE EXPIRACION SE DETERMINA CON UN MEDIDOR DE PRESION (10). SI ESTA SE QUEDARA POR DEBAJO DE UN CIERTO VALOR PRECALCULABLE, SE DESENCADENARA UNA NUEVA FASE DE INSPIRACION. PARA MEJORAR ESTE DESENCADENAMIENTO, LA INVENCION PREVE QUE SE DETERMINE EL FLUJO DE GAS DEL PACIENTE CON LA AYUDA DE UN MEDIDOR DE FLUJO (5, 8) Y QUE SE VARIE EL VALOR DE PRESION PRECALCULABLE DE ACUERDO A ESTE FLUJO DE GAS DETERMINADO.
