Certified Biomedical Equipment Technician (CBET) Practice Exam

When operating an intravenous pump, it is critical to monitor the pressure within the delivery system. Excessive downstream line pressure can create a significant issue. In this scenario, the pump is designed to detect obstructions or excessive pressure that could prevent the fluid from flowing freely. When the pressure becomes too high, this triggers a safety mechanism within the pump, leading to an occlusion alarm.

The activation of this alarm serves as a warning to the biomedical technician or healthcare professional that there is a blockage or excessive pressure in the system. The pump will then take action by ceasing the delivery of medication to prevent harm to the patient, such as potential vessel rupture or infiltration of the IV.

Understanding how intravenous pumps respond to changes in pressure is crucial for those in biomedical equipment technology, as ensuring proper function and patient safety is a primary responsibility. This knowledge helps professionals troubleshoot devices effectively and maintain quality care in a clinical setting.
