Abstract

PROCEDER PARA LA VIGILANCIA PARA LA FILTRACION HAEMOIA, CON EL CUAL SE EFECTUA UN CONTROL INICIAL DE UNA BOMBA ULTRAFILTRATA (40) POR UN LADO Y DE UNA BALANZA (58) POR OTRO LADO, CON ASISTENCIA DE UNA INSTALACION DE VIGILANCIA (74). CON ESTO LA BOMBA ULTRAFILTRADA (40) TRANSPORTA UNA CANTIDAD DE ULTRAFILTRADA A LA BALANZA (58) Y EL RESULTADO SE LLEVA A LA INSTALACION DE VIGILANCIA. AL MISMO TIEMPO SE DA EL NUMERO DE LOS TIEMPOS PRODUCIDOS DE LA BOMBA (40) A LA INSTALACION DE VIGILANCIA (74) QUE CALCULA, DESDE EL VOLUMEN DE BOMBA CONOCIDO DE LA BOMBA DE ULTRAFILTRATO (40), LA CANTIDAD TRANSPORTADA Y COMPARA EL RESULTADO CALCULADO CON EL RESULTADO DE LA BALANZA. SOLO CUANDO LOS DOS RESULTADOS COINCIDEN, SE LIBERA LA MAQUINA-HDF. DESPUES DE EMPEZAR LA FILTRACION HAEMODIA SE COMPARA EL RESULTADO DE HALANZAR ACTUAL CON EL RESULTADO DEL CALCULO QUE LA INSTALACION DE VIGILANCIA (74) CALCULA DESDE QUF, QSUB, Y T (CANTIDAD DE ULTRAFILTRATO PARA TRANSFORMAR Y CANTIDAD DE SUSTITATO TANTO COMO EL TIEMPO DE TRATAMIENTO) AL PUNTO ACTUAL DEL TIEMPO.
