What is the purpose of a nebulizer in respiratory therapy?

The purpose of a nebulizer in respiratory therapy is to deliver medication in the form of a mist, which can be easily inhaled into the lungs. This method is particularly beneficial for patients with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD) because it allows for quick and effective delivery of bronchodilators, corticosteroids, and other medications directly to the airway and lungs. By using a nebulizer, the medication can bypass the swallowing process and systemic circulation, providing targeted relief and a quicker onset of action compared to oral medications.

In contrast, measuring lung capacity involves different techniques such as spirometry, while assisting with oxygen delivery typically involves devices like oxygen masks or nasal cannulas. Monitoring respiratory rate is carried out using clinical observation or electronic monitoring devices, not nebulizers. Each of these other functions serves a distinct purpose and does not involve the same mechanism or goal as the medication delivery provided by nebulizers.
