WebAug 1, 2024 · Introduction. Peak expiratory flow measurement (peak flow) is a simple measure of the maximal flow rate that can be achieved during forceful expiration … WebSep 22, 1997 · Respiratory rate (RR) increases as a function of ventilator flow rate (V˙). We wished to determine whether this is due to a decrease in neural inspiratory time (T i n), neural expiratory time (T e n), or both. To accomplish this, we ventilated 15 normal subjects in the assist, volume cycled mode.
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®. WebMaximum expiratory flow rates from TLC, the forced vital capacity (FVC), the forced expiratory volume in the first second of expiration (FEV 1) and the peak expiratory flow rate (PEFR) are commonly measured in cooperative subjects with a spirometer or flow meter.

WebThe patient does a constant level of work on a treadmill or cycle ergometer for 6 to 8 minutes at an intensity selected to produce a heart rate of 80% of predicted maximum heart rate. The FEV1 and FVC are measured before and 5, 15, and 30 minutes after exercise. Exercise-induced bronchospasm reduces FEV1 or FVC ≥ 15% after exercise.
