What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component PhenX - respiratory - peak expiratory flow rate - PEFR protocol 090801. It is commonly used with the system or sample type ^Patient.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Panel type: Panel
  • Method: PhenX

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • PhenX - respiratory - peak expiratory flow rate - PEFR protocol 090801
  • 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.
