What is the first step when connecting an oxygen system?

The first step when connecting an oxygen system is to connect the regulator. This is crucial because the regulator is responsible for controlling the flow of oxygen from the tank, ensuring it is delivered at a safe and manageable pressure. Proper connection of the regulator ensures that there will be no leaks and that the system is ready for further setup, such as attaching the BMV (Bag-Valve-Mask) or opening the tank valve.

Once the regulator is securely attached to the oxygen tank, it allows for the safe opening of the tank valve, which provides access to the oxygen flow. From there, checks for leaks and attaching any additional components can be performed safely, knowing that the regulator is properly in place. Connecting the regulator first sets up a secure and functional oxygen delivery system, which is essential for ensuring effective emergency response or medical assistance.
