Oxygen Masks


  •  There are numerous types and designs of oxygen masks in use.
  • The most important factor in an oxygen mask use is to insure the masks and oxygen system are compatible.
  •  Crew masks
  • are fitted to the user’s face with a minimum of leakage and
  • usually contain a microphone. Most masks are the oronasal
  • type, which covers only the mouth and nose.
  • A passenger mask may be a simple, cup-shaped rubber
  • molding sufficiently flexible to obviate individual fitting.
It may have a simple elastic head strap or the passenger may hold it to his or her face.
  • All oxygen masks should be kept clean to reduce the danger of infection and prolong the life of the mask.
  •  To clean the mask, wash it with a mild soap and water solution and rinse it with clear water.
  •  If a microphone is installed, use a clean swab, instead of running water, to wipe off the soapy solution.
  • The mask should also be disinfected.  A gauze pad that has been soaked in a water solution of Merthiolate can be used to swab out the mask.
  •  This solution used should contain one-fi fth teaspoon of Merthiolate per quart of water.
  •  Wipe the mask with a clean cloth and air dry.
