The statement that a metered-dose inhaler (MDI) delivers the same amount of medication every time it is used is accurate. MDIs are designed to aerosolize medication in a specific dose with each puff, which ensures that patients receive a consistent and measured amount of medication with each administration. This feature is essential for managing conditions like asthma, as it allows for precise delivery of bronchodilators or corticosteroids directly to the lungs, enhancing efficacy and safety in treatment.

Understanding this functional aspect of MDIs is critical for both patients and healthcare providers, as it influences proper usage and the effectiveness of treatments for respiratory conditions. Regular calibration and patient technique in using the inhaler ensure that the medication delivery is as intended, thereby maximizing therapeutic outcomes.
