Mastery of pMDI technique, asthma control and quality-of-life of children with asthma: A randomized controlled study comparing two inhaler technique training approaches.

Objective: Verbal counselling (VC) is the clinical standard for training patients on correct inhaler use. Patients fail to recall their VC with time. Ethical approval was obtained to compare the pressurized metered dose inhaler (pMDI) VC with Trainhaler (TH), a novel pMDI inhalation flow and technique training device, in children with asthma.
