What is the function of a reserve supply in the central supply system?

The function of a reserve supply in the central supply system is specifically designed to supply gas when the primary source is exhausted. This becomes crucial in medical settings where continuous availability of medical gas is essential for patient care. The reserve acts as a backup to ensure that if the primary supply runs low or is depleted, there is an alternative source ready to maintain the flow and pressure of medical gases without interruption.

In medical environments, where the failure to deliver gases like oxygen could lead to severe consequences for patients, having a reliable reserve supply enhances the safety and reliability of the medical gas system. It ensures that staff can respond quickly to unexpected demands or outages, thereby protecting patient health and safety effectively.

While other options suggest different roles that might be relevant within a broader context of medical gas supply systems, the reserve supply's primary purpose is distinctly to keep the flow of medical gases steady during times when the main supply is not available.
