What is one common sign that a dialysis machine may need service?

The presence of unusual sounds during the operation of a dialysis machine is a clear indication that it may require servicing. These sounds can often signal mechanical issues, problems with the pump or filters, or other malfunctions that could affect the machine’s performance and, consequently, patient safety. As dialysis machines are high-precision devices, any deviation from normal operational sounds should be taken seriously and investigated promptly.

In contrast, consistent alarms indicating successful functioning, stable patient vitals before treatment, or low frequency of alarms during sessions typically suggest that the machine is working properly and that the patient’s condition is stable. Therefore, these situations do not point towards the need for immediate service or maintenance of the dialysis machine. It's crucial to monitor for any atypical indicators like unusual sounds, as they can prevent potential complications in patient care.
