What type of device does the abbreviation "neb" refer to?

The abbreviation "neb" refers to a nebulizer, which is a device used to deliver medication in the form of a mist directly into the lungs. This method is particularly effective for individuals with respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD), where rapid and direct medication delivery to the airway is essential.

A nebulizer works by using a compressor to vaporize medication into fine droplets that can be inhaled through a mask or mouthpiece. It allows for a more effective treatment of respiratory issues compared to pills or injections, which may not reach the lungs as directly or quickly. The other options, while related to medication delivery, do not involve the specific function or mechanism associated with a nebulizer.
