There will always be a range of normal values; not everyone can be expected to have exactly the same value. Men can have peak flow values as low as 100 liters/minute less than the average value shown and still fall within the normal range. Women can have peak flow values as low as 80 liters/minute less than the average value shown and still

Aug 18, 2019 This measure is called a "peak expiratory flow," or "PEF. Peak flow values are best if they are checked at the same time each day, preferably 

Predicted normal values for FEF can be calculated and depend on age, sex, height, mass and ethnicity as well as the research study that they are based on. Normal FEV1 values vary between individuals, and can depend on the following factors: age; gender; height; race The normal volume time curve has a rapid upslope and approaches a plateau soon after exhalation. volume (FEV1). Normally the volume exhaled in one second is approximately 80% of the total volume, while the volume after 3 seconds is equal to the FVC PEF = Peak expiratory flow: er det maksimale flow/ hastighed målt ved den maksimale forcerede udånding. Alle disser værdier er med til at danne et billede af hvordan lungernes tilstand er.

The peak expiratory flow (PEF, also known as a peak flow or peak flow rate) is the maximal rate that a person can exhale during a short maximal expiratory effort after a full inspiration. Your child's number can be determined from predicted normal peak flow values for people of the same age and height. See the chart at the end of this sheet for average peak flows for healthy children and teenagers. Your health care professional can also determine your child's peak flow number based on a personal baseline. Generally speaking, results nearest to 100% predicted are the most normal, and results over 80% are often considered normal.

Normal PEF numbers vary based on gender, age and height. needs. Once your range has been determined, the scale selector at the top of the device can be.
