Question

Quizplus · Accepted Answer

Dry powder inhalers (DPIs) may not be effective in acute exacerbation of asthma as they require a higher inspiratory flow rate which may not be possible in a patient experiencing an acute attack. Metered-dose inhalers (MDIs), spacer devices, and nebulisers are all effective options for delivering medication during an acute asthma attack.
