The peak expiratory flow rate is the "measurement of the maximum rate of airflow attained during a forced vital capacity determination. Common abbreviations are PEFR and PFR."[1]
Effectiveness if monitoring patients with obstructive airways disease
In randomized controlled trials of adult patients, use of the PEFR did not improve upon instructing patients in how to monitor the symptoms of their lung disease.[2][3]
Among children, some children seem to benefit from PEFR monitoring.[4][5]
