Dry powder inhalers are designed with resistance to airflow so that a respirable cloud of particles is generated during inhalation. Some of these devices require a certain inhalation rate to produce a consistent dose of respirable particles. The aim of the study was to determine the inhalation rate of elderly @entity1 with @entity1030 ( @entity1030 ) when they inhale through a Turbuhaler and assess the potential of the In-Check Meter to identify inhalation rates. Their peak inhalation rate using a normal inhalation, pre- and post-counselling, was measured using a Turbuhaler Trainer and an In-Check Meter. Spirometry was also measured. Seventy-four @entity1030 @entity1 with a mean (SD) age of 79.7 (8.4) years and forced expiratory volume in 1 sec (FEV1) 41.9 (12.8)% predicted. Pre-counselling 14 obtained a rate of <30 l @entity1009 ) with the Turbuhaler Trainer, 31 from 30 to 40 @entity1009 ), 23 between 40-60 l @entity1009 ) and 6 > 60 l @entity1009 ). The median (range) peak inhalation rates with the In-Check Meter were 50 (50-70), 70 (50-130), 100 (60-200) and 225 (200-250) l @entity1009 ). Post-counselling 7, 16,41 and 10 achieved the respective peak inhalation rates using the Turbuhaler Trainer Similarly the In-Check inhalation rates were 50 (50-60), 70 (50-130), 90 (60-200) and 250 (200-270) l @entity1009 ). The results highlight the potential of the In-Check Meter to identify @entity1 ' inhalation rates through dry powder inhalers.

Measurement of peak inhalation rates with an in-check meter to identify an elderly XXXX 's ability to use a turbuhaler.
