What is required to connect a BMV to an oxygen system?

To connect a BMV (Bag-Mask-Valve) to an oxygen system, an inlet port is essential. The inlet port serves as the point where the oxygen supply is introduced to the BMV, allowing for a controlled flow of oxygen to be delivered to the patient. This connection is crucial for ensuring the device can effectively administer supplemental oxygen during respiratory assistance.

While other options like a regulator input or connector hose are components that may be relevant in different contexts, they do not specifically define the required interface for connecting a BMV to an oxygen system. The pressure gauge, on the other hand, measures oxygen levels or pressure but does not play a direct role in the connection itself. Thus, the inlet port is the necessary feature that enables the linkage between the BMV and the oxygen supply system.
