Modo Respiratorio, Presión, Volumen, Flujo, Compliance, Simulación, ResistenciaResumen
Hoy en día las personas que presentan insuficiencia respiratoria aguda y que no responden a tratamientos no invasivos, requieren ventilación mecánica. Esto se vio incrementado en la pandemia del COVID 19, en donde los gobiernos y empresas incrementaron la producción, investigación de ventiladores mecánicos. Uno de los pasos principales para el desarrollo de un dispositivo médico es su simulación. El presente artículo muestra el procedimiento necesario para modelar matemáticamente ondas de volumen, flujo y presión en el modo ventilación mandatorio continúa controlada por presión (PC-CMV) y el modo ventilación mandatorio continúa controlado por volumen. Para su desarrollo se tomaron en cuenta los parámetros de entrada como la compliance, resistencia, frecuencia respiratoria, tiempo inspiratorio, tiempo espiratorio, tiempo pausa, PEEP, PIP y volumen tidal para su simulación en el software Matlab y obtención de parámetros ventilatorios en el modo PC-CMV y VC-CMV.
