Which components make up the self-contained portions of the central supply system?

The self-contained portions of the central supply system are fundamentally represented by supply sources. These sources are crucial for providing the necessary medical gases for patient care. In a central supply system, supply sources include bulk gas systems, liquid gas storage tanks, and other methods for storing and delivering gases like oxygen and nitrous oxide.

These supply sources are designed for safety and efficiency, ensuring that medical gases are readily available when needed and are stored in a manner that minimizes risks associated with high-pressure gases. Each component within the central supply system works collaboratively to ensure a constant and reliable flow of medical gases to various points of use throughout the healthcare facility.

In contrast, central distribution units and pressure regulators play roles in the distribution and management of gas delivery but are not classified as self-contained supply sources. Operating tools are also not considered part of the self-contained supply system; rather, they are utilized for maintaining and operating the system. Thus, supply sources best encapsulate the essence of the self-contained portions of the central supply system, highlighting their foundational importance in medical gas management.
