What is the function of an emergency oxygen supply connection?

The function of an emergency oxygen supply connection is to provide temporary oxygen when the main supply is disrupted. This system is crucial in medical settings where oxygen is vital for patient care. In the event of a failure in the primary oxygen delivery system, the emergency connection ensures that there is a backup available to maintain a continuous supply of oxygen. This capability is essential for situations where immediate access to oxygen can impact patient outcomes, such as during power failures or equipment malfunctions.

While the other options present different functions, they do not apply to the purpose of an emergency oxygen supply connection. For instance, supplying nitrogen is unrelated to oxygen's role in patient care. Managing gas pressure, although important in the context of gas systems, does not pertain specifically to the emergency function. Filtering impurities from the air is a process associated with air quality control rather than an emergency oxygen supply. Therefore, the focus of the emergency connection is exclusively on providing a reliable oxygen source during incidents that could impede normal supply.
