When should the vacuum system alarm activate?

The vacuum system alarm is designed to activate at a specific threshold to ensure that the vacuum system can safely and effectively remove gases and fluids from a medical environment. In this case, the alarm is set to activate below 12 inches of mercury (in Hg). This threshold is established to provide a safety margin that alerts staff to potential issues with the vacuum system which could compromise its performance.

When the pressure drops below this level, it indicates that the vacuum system is not functioning optimally, potentially leading to insufficient suction for medical procedures. Timely alerts help in addressing the vacuum system's integrity and operational capacity, allowing for quick intervention to maintain patient safety. By setting the alarm at this point, it allows healthcare facilities to operate within safe parameters and alerts the staff before the pressure reaches critically low levels that could hinder patient care.

While other thresholds may provide alarms, the selection of 12 in Hg as the activation point is intended to balance operational efficiency and safety in a medical setting.
