Final answer:
An atomizer is a device that sprays a liquid medication as a spray into a nostril. It uses a squeeze bulb to create a jet of air that entrains drops of the medication. It allows the medication to be delivered in a fine mist, making it easier to inhale through the nose.
Step-by-step explanation:
An atomizer is a device that changes a liquid medication into a spray and pushes it into a nostril. It works by using a squeeze bulb to create a jet of air that entrains drops of the medication, similar to how a paint sprayer or a perfume atomizer works. This allows the medication to be delivered in a fine mist, making it easier to inhale through the nose.
For example, an albuterol inhaler is a type of atomizer commonly used to treat asthma. It sprays a medication called albuterol, which helps to open up the airways and relieve breathing difficulties.
