• A Nebulizer is a drug delivery device that turns liquid medications into fine mist, allowing easy inhalation into lungs through mouthpiece or facemasks. • They are used for variety of healthconditions, includingCOPD,asthma, and cystic fibrosis or another lung diseases. On such conditions your healthcare provider will prescribe a medicine that you need to take through nebulizer, you will sit near by the machine and inhale the gas mixture comes from it. • Depend on the patient condition time duration and dosage of medications will varies. • To deliver a drug by nebulization, the drug first need to dispersed in liquid solution,then it use compressed air,oxygen or ultrasonic waves to break up the solutions into small aerosol particles suitable for inhalation. • Compressed air or Oxygen applied will travel at a high velocity, creating low pressure at the outlet of liquid feed tube. This pressure difference inside the liquid and outlet of the feed tube causes fluid from reservoir to be drawn up into and out of the tube (Bernoulli’s principle). • Nebulizers should be cleaned properly and air dried after every usage, or else there will be chance of forming bacteria and fungus inside the reservoir. • Nebulizer is simple as vaporizer that we used in home, only the dosage of medication and timing is more important.
