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.
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.
