Definition

Glossary
PEF: Peak Expiratory Flow (PEF), also called Peak Expiratory Flow Rate (PEFR), is a person’s maximum speed of expiration, as measured with a Peak Flow Meter. It measures the airflow through the bronchi of the lungs and shows the degree of obstruction in the airway.

FEVI: Forced Expiratory Volume (FEV1) calculates the amount of air that a person can force out of their lungs in 1 second. It is an indicator of the reversibility of airway obstruction and the primary indicator of impaired lung function,

PEF %: Measured PEF/Expected PEF 100%

FEV1%: Measured FEV1/Expected FEV1 100%

Expected value
The expected value (target value is usually calculated based on statistics. It varies according to race, gender, age, and height According to the variation between the actual tested value and the expected value, your PEF readings are classified into three measurement zones, green, yellow, and red. The device will show these colors with results accordingly.

Green: PEF6806, a peak fiow reading in the green zone indicates that the lung function management is under good control,
Yellow: 50% PEF<80%, your peak flow reading indicates caution. It may mean respiratory airways are narrowing, and additional medication may be required.
Red: PEF-C50%, your peak flow reading indicates a medical emergency. Severe amway narrowing may occur, and immediate action must be taken. This would usually involve contacting a doctor or hospital

Note:
Recommendation from: National Institutes of Health (NIH)
FEV1 is generally used as an indicator to measure airway obstruction. Its measurement, evaluation, and interpretation are complicated. It is recommended to consult a doctor or consult professional publications,

b Field strengths from fixed trarismitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should beconsidered. If the measured field strength in the location in which th SMPF-25 Peak Flow Meter is used exceeds the applicable RF compliance level above, the SMPF-25 Peak Flow Meter should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as réorlenting or relocating the SMPF-2S Peak Flow Meter.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3v/m.
