Inhalers are primarily used for which of the following purposes?

Inhalers are primarily designed to deliver aerosolized medication directly into the lungs for quick absorption and effectiveness. By generating a fine mist or aerosol, inhalers allow medication to be inhaled in a concentrated form, targeting respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). This method of delivery is beneficial because it minimizes the potential for systemic side effects and allows the medication to act swiftly on the airways.

The other options do not accurately reflect the primary function of inhalers. While high flow oxygen is critical in various medical emergencies, it is not the purpose of inhalers, which focus on delivering medication. Monitoring air quality is an entirely different field, typically relying on environmental sensors rather than personal inhalation devices. Lastly, although humidifying inspired air is important for certain clinical situations, it is not a function of standard inhalers, which specifically target medication delivery rather than air quality or humidity levels.
