故障现象：我院一台Baxter550型透析机出现dialysatePrssure（透析液压力）报警。同时，伴有TMP（跨膜压）Pressure表指针指向一50mmHg，而且TMPAdjllst（跨膜压调节器）不可调。分析与检修：出现上述故障的原因一般有：①透析液压力传感器性能改变；＠PressureControl／CPUEXD
Symptoms: A dialysatePrssure (dialysis fluid pressure) alarm occurs on a Baxter 550 dialysis machine in our hospital. At the same time, with the TMP (Transmembrane pressure) Pressure table pointer points to a 50mmHg, and TMPAdjllst (transmembrane pressure regulator) is not adjustable. Analysis and Maintenance: The above-mentioned failures are generally caused by: 1 Change in the performance of the dialysate pressure sensor; @PressureControl/CPUEXD
