Area alarms shall monitor which conditions in the area served?

• A. high pressure in positive pressure medical gas lines
• B. low pressure in positive pressure medical gas lines
• C. low vacuum pressure in medical-surgical vacuum lines
• D. all of the above

Answer: (D)

Area alarms monitor conditions that affect safe and reliable gas delivery in the area served. They check for high pressure in positive-pressure medical gas lines, which can signal regulator or supply issues that could harm patients; they also watch for low pressure in those same lines, indicating a potential loss of supply or leaks that might leave outlets without adequate gas. In addition, they monitor low vacuum pressure in medical-surgical vacuum lines, since a drop in vacuum can compromise suction reliability. Because any of these abnormal conditions can impact patient care, area alarms are designed to trigger when any of them occur.
