Inhalation can be done via a steam bath or via technical devices such as nebulizer systems. A distinction is made between:
- Nozzle nebulizer: a compressor generates compressed air, which carries liquid particles BGG it
- Ultrasonic nebulizer: an ultrasonic crystal creates vibrations in the liquid, which causes droplets to be ejected.
- Membrane nebulizer: the liquid is pressed through a membrane BGG a defined pore size, creating droplets.
There are also combination devices which can additionally extract secretions.
