| Measure | Time frame |
|---|---|
| Measurements: the Mag-Flo device will be used to record 5 inhalations. The total duration of the inhalation and the duration of inhalation in the optimum low range will be recorded. During this assessment of the subjects ability the green light will not be operative in order to check the technique with the subject blinded. The mean duration of the best (i.e. longest time of inhalation in the correct flow range) two attempts writ be analysed as well as the mean and standard deviation of all 5 attempts. Spirometry to record PD/I, FVC and REF wilt he performed by technicians blind to he subjects grouping and will be according to British Thoracic Society guidelines before and 20 minutes after inhaling their prescribed dose of inhaler drug.
