fits over the nose and mouth and has an incoming, one way valve near the nose and two outgoing, one way valves on the side. So, when one breathes in the two outgoing valves are closed and when breathing out the incoming valve closes, thus one is getting the intended 100% 02. Can't believe your doc hasn't heard of it and as for the nurse, sounds like she needs to go back to school. Good luck!
