Chaney et al. (2004): Funhaller study - Lesson

Flow diagram of the Funhaler study showing baseline usual spacer, the Funhaler with whistle and spinning disc, short home use, and improved adherence outcomes

Chaney et al. (2004) asked whether a modified asthma spacer called the Funhaler could improve how well young children took their medication. You may see the topic written as "Funhaller" in revision guides, but the device in the article is usually called the Funhaler.
