What is a common limitation of nebulizers compared to MDIs?

The common limitation of nebulizers compared to metered-dose inhalers (MDIs) is often their increased device complexity. Nebulizers require more setup and maintenance than MDIs, which are usually simpler to use—patients can typically just shake the inhaler and use it without additional assembly or cleaning. Nebulizers may need to be connected to a power source, require specific medication formulations, and involve cleaning of multiple parts to avoid contamination and ensure effective delivery. This complexity can lead to inconsistencies in use and compliance among patients, especially those who are elderly or have limited mobility.

In contrast, MDIs are comparatively straightforward: they deliver a specific dose of medication with a single actuation, allowing for ease of use. Understanding the differences in device design and patient interaction is crucial for effectively administering respiratory treatments and ensuring adherence to prescribed regimens.
