LOINC long common name : PhenX - respiratory - peak expiratory flow rate - PEFR protocol 090801;
LOINC short name : Resp peak expiratory flow rate proto;
LOINC description : A patient is instructed to inhale deeply and blow into a peak expiratory flow monitor
three times. Peak Expiratory Flow Rate (PEFR) can be measured as part of spirometry
testing (see Spirometry measure) or as a separate measurement. The highest PEFR value
is typically used for analysis. A minimum of three acceptable blows is necessary.
The maneuver can be performed in either the sitting or standing position, but one
of these options should be used in a standardized manner within a particular study.;
