How does it work?
Pressurized air passes through the tube and turns the liquid medicine into a mist. During an asthma attack or a respiratory infection, the mist may be easier to inhale than the spray from a pocket inhaler. When your airways become narrow — like during an asthma attack — you can’t take deep breaths. For this reason, a nebulizer is a more effective way to deliver the medication than an inhaler, which requires you to take a deep breath.

Nebulizer Types:- 

1. Compressed-air nebulizer:- 
 Also called jet nebulizer or atomizer, this device has a compressor that converts medicated solution into vapors

2. ultrasonic nebulizer :- Ultrasonic humidifier uses ultrasonic energy to transform liquids into cloud-like particles.
