Anesthesia Technician Practice Exam

What should be done if the pressure gauge shows a significant drop during the system check?

1. Recheck the vaporizers

2. Calibrate the pressure gauge

3. Inspect for possible leaks

4. Replace the pressure gauge immediately

The correct answer is: Inspect for possible leaks

When the pressure gauge indicates a significant drop during the system check, it is essential to inspect for possible leaks. A drop in pressure can signify that gas is escaping from the system, which could lead to inadequate delivery of anesthetic gases and pose a safety risk to the patient. By identifying and addressing any leaks, the integrity of the anesthesia delivery system can be restored, ensuring that the appropriate pressures are maintained for effective anesthesia administration. Evaluating other options provides a clearer understanding of why inspecting for leaks is the most appropriate course of action. While rechecking the vaporizers is important for ensuring that they are functioning correctly, it may not directly address the issue of pressure loss if there is a leak present. Calibrating the pressure gauge could provide more accurate readings but does not resolve the fundamental problem of a pressure drop due to potential leakage. Replacing the pressure gauge is typically unnecessary unless it is confirmed to be malfunctioning, which would be addressed only after ensuring the entire system is leak-free. Thus, prioritizing the inspection for leaks is the critical step in troubleshooting a significant drop in pressure during system checks.
