Certified Hyperbaric Technologist Practice Test

What device is primarily used to prevent suction injury inside a hyperbaric chamber?

1. Exhaust fan

2. Vacuum relief device

3. Pressure release valve

4. Suction control gauge

The correct answer is: Vacuum relief device

A vacuum relief device is essential in preventing suction injuries inside a hyperbaric chamber. Suction injuries can occur due to rapid pressure changes or improper regulation of air flow within the chamber, which may create vacuum conditions that could harm patients or equipment. The vacuum relief device helps maintain appropriate pressure levels and allows air to enter the chamber if a negative pressure is detected, effectively neutralizing the risk associated with suction. This device ensures a safe environment for patients undergoing hyperbaric treatment by providing immediate relief of any negative pressure that may develop. By seamlessly managing the chamber's internal pressure, the vacuum relief device plays a vital role in enhancing patient safety and comfort during therapy. Understanding its function is crucial for hyperbaric technologists, who must prioritize safety and effective operational practices within the chamber.
