When preparing to give medical oxygen, what is essential to ensure the oxygen delivery system is in working condition?

Inspecting the pressure gauge is a critical step to ensure that the oxygen delivery system is in working condition. The pressure gauge indicates the level of oxygen available in the tank. If the gauge shows a low pressure or is faulty, there may not be enough oxygen to provide effective support in an emergency situation. Therefore, it is essential to check the pressure gauge before using the oxygen system to ensure it is full and ready for use.

Other factors, such as regular cleaning and maintenance, are important for overall safety and functionality of medical equipment, but they do not directly assess the immediate readiness of the oxygen supply. Ensuring all components are lubricated could also create risks, as lubricants can be flammable and aren’t advisable in an oxygen-rich environment. Confirming that the oxygen tank exceeds 150 psi, while useful information, is not the standard requirement for readiness; the current gauge reading directly provides the necessary information regarding the tank's operational capacity.
