Podcast 616: MDIs for the Win

Contributor: Aaron Lessen, MD

Educational Pearls:

Contrary to many assumptions, meter-dose inhalers (MDIs) are as effective as nebulizers in pediatric and adult patients
Nebulizers are associated with higher rates of tremor, tachycardia; they cost more and are associated with longer ED stays
Though it may take some convincing, in a patient that is physically able, using an MDI with spacer appears to be the better option - and that was even before COVID.
