A biomedical technician (biomed) contacted fresenius technical support to ask about an a.24 alarm code that occurred on a 2008t hemodialysis (hd) machine.The biomed was performing a machine evaluation because of an incident that occurred while the device was in-use a few days prior.It was reported that during a treatment, the blood pump speed spiked from 50 ml/min to 600 ml/min and infiltrated the patient.The biomed stated the treatment was discontinued and the patient went home.Additional information was obtained through follow-up with the biomed and the hd facility¿s charge nurse (cn).The cn confirmed the initially reported details.The cn stated the patient care technician (pct) had set the blood pump to a low speed of 50 ml/min, and when they closed the door on the blood pump, the speed jumped up to 600 ml/min.This was noticed right away, and it was reported that an a.24 alarm had also occurred.Because of the high increase in pump speed, the patient¿s vein was infiltrated and fluid spilled out into the non-vascular space of the patient¿s arm.It was confirmed that there was no blood loss due to the reported event.The cn reiterated that it was caught very quickly, and thus, the consequences were not severe.It was reported that the patient¿s blood was returned through the arterial line.The patient¿s treatment was discontinued and they were sent home to ice their arm.No medical intervention was required.The patient¿s arm was reportedly bruised when they returned to the hd facility for their subsequent treatment.However, the patient was cannulated without issue and able to complete their normal treatment.The patient was said to be continuing their regular hd therapy without further incident.Following the infiltration event, the 2008t machine was pulled from service for evaluation and the biomed confirmed that an a.24 alarm occurred during testing.The biomed replaced the motor/tach assembly and the a.24 alarm went away.No other parts had to be replaced or calibrated.After completing the repair, the machine passed all testing and was returned to service.The biomed stated there have been no further issues with the machine.The motor/tach assembly that was replaced was available to be returned for evaluation.The biomed stated they would send the part back via returned goods authorization (rga).
