A medical nebulizer is a device used in respiratory therapy to deliver medication directly into the lungs. It converts liquid medication into a fine mist or aerosol that can be inhaled by the patient. The mist is generated by compressing air or oxygen through the liquid medication, creating a cloud of tiny droplets that can easily be inhaled.

Nebulizers are commonly used to administer medication for respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, and other respiratory infections or diseases. The mist generated by the nebulizer allows the medication to reach the airways and lungs directly, providing targeted and effective treatment.

Nebulizers are often used by individuals who have difficulty using inhalers or require higher doses of medication. They are particularly beneficial for infants, young children, and elderly individuals who may have difficulty coordinating their breathing to use an inhaler properly.
