At what level of carbon monoxide (CO) does a local alarm in a medical air system trigger?

The local alarm in a medical air system is designed to trigger at 10 parts per million (ppm) of carbon monoxide (CO). This threshold is established to ensure patient safety, particularly in medical environments where air quality is critical.

At this level, the detection of carbon monoxide allows for immediate response and mitigation efforts to prevent exposure to patients and healthcare staff. Medical facilities are required to monitor and manage the air quality actively, as carbon monoxide can pose serious health risks, especially in vulnerable populations. Setting the alarm at 10 ppm strikes a balance between ensuring safety and minimizing unnecessary alarm triggers, which could lead to alarm fatigue among staff.

The other levels, while still relevant in the context of air quality monitoring, do not serve the same purpose for immediate safety response in medical air systems as the 10 ppm threshold does.
