A nebulizer is a compressed air machine used to administer liquid respiratory medication in the forms of a mist. Some patients with respiratory problem find it easier and more pleasant to breathe their respiratory medications with a nebulizer than with an inhaler. Unlike inhalers, nebulizers may deliver a dose more accurately and the cost is paid for by Medicare.
A variable oxygen-concentration high flow nebulizer provides variable concentrations of humidified oxygen and delivers aerosal medication such as albuterol or Mucomyst or acetylcysteine Mucosil). It is available in a portable unit. They may be more effective for patients who have difficulty with mucous secretions.
