Predictive Normal Values have been calculated for women and men of different ages and heights, and have been adapted (with agreement from the original Authors) for use with the new EU Scale / EN peak flow meters.

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 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 fall within the normal range. A chart called a ‘nomogram’ can be used to estimate your predicted peak flow if you are male or female, your age and height. It is important to remember that everyone is different and you should be guided by what is normal for you. Measuring your peak flow when you feel well will establish your normal or best peak flow.
PEAK EXPIRATORY FLOW RATE - NORMAL VALUES For use with EU/EN scale PEF meters only Adapted by Clement Clarke for use with EN / EU scale peak flow meters from Nunn AJ Gregg I, Br Med J ; In me n, readings up to L/min lower than predicted are within normal limits. For women, the equivalent figure is 85File Size: 52KB. Peak flow meters come in two ranges to measure the air pushed out of your lungs. A low-range peak flow meter is for small children, and a standard-range peak flow meter is for older children, teenagers and adults. An adult has much larger airways than a child and needs the larger range. There are several types of peak flow meters available.
