Additional Manufacturer Narrative
This report has been identified as b.Braun medical, inc.Internal report number (b)(4).The technical inspection of the dialog+ machine did not show any malfunction.It operated as intended.The evaluation of the data record of the dialog+ machine showed a successfully passed preparation phase.In the first 37 minutes of the therapy numerous arterial pressure alarms (arterial pressure - lower limit or arterial pressure - lower limit (sup)) were triggered often followed by venous pressure alarms (venous pressure lower limit (sup)) due to the blood pump stop because of the alarm.Following these alarms, the dialog+ machine switched into patient-safe mode (blood pump stop, venous tube clamp sakv closed).From the trend data, the cause for these alarms is not comprehensible.The alarms were all acknowledged in a timely manner by the operator.About 37 minutes into therapy an air alarm was triggered (sad-air! and s.A.D.(sup)).Following this alarm, the dialog+ machine switched into patient-safe mode.The alarm was acknowledged by the user and the therapy was continued.Six minutes later, the alarm abpm: sys press.Is too low was triggered because the blood pressure measured by the respective module of the dialog+ machine was 97/64 mmhg, pulse rate 94 bpm and thus below the set limit.Ten seconds later minimal uf was activated by the operator and shortly thereafter, no more red was detected at the red detector of the sad, indicating that the blood in the extracorporeal circuit had been returned to the patient.This was obviously the time when the therapy was stopped because the patient had developed the described symptoms and was disconnected from the dialysis machine.The evaluation of the trend data show no indication of a malfunction.The technical inspection of the dialog+ on-site as well as the evaluation of the data record show that the dialysis machine operated as intended.
