What device is used to protect patients from receiving air during dialysis?

The device that protects patients from receiving air during dialysis is the air detector. This device is specifically designed to monitor the blood line for any presence of air bubbles. In a dialysis setting, air entering the bloodstream can cause serious complications such as air embolism, which can be life-threatening. The air detector continuously scans the blood flow for any air that may inadvertently enter the system, and if detected, it can trigger alarms or shut off the pump to prevent any air from being infused into the patient’s bloodstream. This makes it a critical safety feature in maintaining patient safety during the dialysis process.

In contrast, the pressure gauge measures the pressure within the circuit and does not specifically monitor for air; the flow meter assesses the rate of fluid flow but does not indicate the presence of air; and the temperature sensor monitors fluid temperature, which is also not related to air detection in the dialysis lines.
