How do you wear the Portable Oxygen Bottle?

• A. Turn on the POB by rotating the knob to ON position
• B. Disconnect the mask and cap the mask if for single use
• C. Squeeze the bag before turning on
• D. Don across the chest by putting arm through strap and over the head

Answer: (D)

Wearing a portable oxygen bottle is about securing the unit so oxygen is ready to use and won’t shift during movement. The correct method is to don it across the chest by putting your arm through the strap and pulling it up over the head so the bottle sits on the chest. This positioning keeps the regulator and tubing accessible and stable, ready for connecting the mask if needed.

Turning the unit on by rotating a knob, or disconnecting or capping a mask if it’s single-use, or squeezing a reservoir bag before turning on aren’t the proper steps for the act of putting the POB on. They may be part of later use, but they don’t describe how to wear the device correctly.
