WebMay 16, 2013 · Peak Inspiratory Flow Rate (PIFR) is defined by the fastest flow rate noted during the inspiratory cycle. Inhaled medication plays an important role in the treatment of chronic obstructive pulmonary disease (COPD), with dry powder inhalers (DPIs) increasingly replacing metered dose inhalers (MDIs). DPIs are interesting as they do not require ... Webat a continuous flow rate of 85 or 95 L/min; gas/vapor cartridge and canister testing is done at continuous flow rates corresponding to V I values of 30-64 L/min (CEN, 2000a; CEN, 2000b; CFR, 1995). Because it is known that V I and peak inspiratory flow rates (PIF) exceed these values at higher work rates, it has R A
