WebMar 28, 2013 · In other words, under the prevailing conditions, the respiratory system is globally limited as flow generator even during tidal expiration, and greater expiratory flow rates may be achieved just by increasing operating lung volumes, (i.e., moving progressively the end-expiratory lung volume (EELV) towards total lung capacity). WebDPIs have internal resistance and some patients may not be able to inhale an optimal amount of powder deep into the lower respiratory tract. Peak inspiratory flow rate (PIFR), the measure of a patient’s inspiratory effort, can be used to assess a patient’s ability to generate adequate inspiratory flow rate from DPIs such as the DISKUS®.
