nebulize

Nebulize is a verb meaning to convert a liquid into a fine mist or aerosol, typically so that the droplets can be inhaled or dispersed. In medicine, nebulization uses a device called a nebulizer to deliver aerosolized medication directly to the respiratory tract, often for patients with asthma, COPD, or other lung conditions.

Nebulization devices vary. Jet nebulizers use compressed air; ultrasonic and mesh nebulizers use vibration or membrane perforation to produce droplets. Particle sizes commonly range from 1 to 5 micrometers, influencing where in the lungs the drug deposits. Treatments are usually administered via a mouthpiece or face mask and may require oxygen support.

Outside medicine, nebulization refers to creating aerosols for laboratory analysis and industrial processes, such as introducing liquids into aerosol generators for spectrometry or mass spectrometry, or delivering fine droplets in agricultural spraying or humidification.

Etymology: from the Latin nebula meaning cloud, through French nébuliser, adopted into English as nebulize in the 19th or early 20th century.

Safety and handling: devices and consumables should be kept clean to prevent contamination. Use prescribed medications only as directed; improper nebulization can cause infection or reduced efficacy. Proper maintenance and cleaning are important.
