Web30 aug. 2024 · Background. Peak expiratory flow rate (PEFR) is the maximum flow rate (expressed in liters per minute [L/min]) generated during a forceful exhalation, starting from full inspiration. [ 1] PEFR primarily reflects large airway flow and depends on the lung recoil, voluntary effort, and muscular strength of the patient. WebMVV tests the overall function of the respiratory system. It is influenced by airway resistance, respiratory muscles, compliance of the lungs and/or chest wall, and ventilatory control mechanisms. Length of Test: 20 minutes.
