What is the function of a NEB in a medical context?

In a medical context, the function of a nebulizer (NEB) is to deliver medication in aerosol form. This device is particularly useful for administering respiratory medications, such as bronchodilators or corticosteroids, directly to the lungs. By converting liquid medication into a fine mist, a nebulizer allows for more effective absorption of the drug through the respiratory tract, which is essential for treating conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory illnesses. Using aerosolized medication helps patients who might have difficulty using inhalers, providing them with immediate relief and effective treatment options.

The other options, such as providing oxygen therapy, monitoring blood pressure, or measuring lung capacity, refer to different medical devices or tools that serve distinct purposes in patient care. A nebulizer specifically focuses on aerosolized medication delivery, making it an essential tool in managing respiratory conditions.
