Expiratory flow should never return to the zero baseline in APRV. Instead, cycling should occur at 50% to 75% of peak expiratory flow to maintain adequate intrinsic PEEP to prevent atelectasis and derecruitment. WebNov 14, 2024 · Introduction. The peak expiratory flow (PEF, also known as a peak flow or peak flow rate) is the maximal rate that a person can exhale during a short maximal expiratory effort after a full inspiration. In patients with asthma, the PEF percent predicted correlates reasonably well with the percent predicted value for the forced expiratory … bitz and bob characters
