Peak Flow - EN 23747 New Peak   Expiratory Flow Standard

 

How will the change affect me as a:

Predictive Normal Values (Nomogram, EU scale)

The change in scale for peak flow meters will result in PEF readings that are different, depending on whether the individual has used a Wright scale meter, or the new EU scale meter.

Sometimes, it is useful for health professionals to have a guide as to what peak flow could be expected from each individual, if they didn't have asthma.

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 23747 peak flow meters.

As a general rule, if your average reading is frequently one-third or more below your best it may mean that your asthma is not controlled.

If you ever have difficulty breathing or cannot obtain relief with a reliever inhaler, you should seek emergency help.
