The small-volume nebulizer is the device commonly used to deliver nebulized medications. This device functions by turning liquid medication into a fine mist, enabling it to be inhaled directly into the lungs through a mouthpiece or mask. This method is particularly effective for patients with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), as it allows for the medication to be absorbed more efficiently in the airways and provides immediate relief of symptoms.

In contrast, a metered-dose inhaler delivers medication in a specific dosage but does not create a mist; it relies on the user’s ability to coordinate inhalation with the actuation of the device. Though effective, it may not be suitable for all patients, especially those who have difficulty with hand-breath coordination.

A continuous positive airway pressure machine is primarily used to keep the airways open in patients with obstructive sleep apnea and is not intended for nebulizing medications. An oxygen concentrator is designed to deliver supplemental oxygen but does not administer medication, making it distinct from delivery devices meant specifically for nebulization.
