Percentage increase in FEV 1 plotted against time following inhalation of 500mcg of terbutaline at 25L/min or 80L/min shows slow inspiratory flow rate is more efficient in delivering ...

It displays information on how well they are inhaling their medication, based on an assessment of their inspiratory flow rate, categorising results according to good, fair, and low/no inhalation.

Tight regulation of the breathing pattern (due to breath holding), at high flow rates and lung volumes, is required. Swim training has been shown to improve inspiratory muscle function3 suggesting ...
