These changes may require special treatment of your condition according to the action plan
given to you by your physician or licensed healthcare professional which will tell you when
and how often to use your
SMART ONE OXI
meter. They also will explain how your PEF and
FEV1 measurements help them monitor your lung function and how well treatments are
working.

DETERMINING YOUR PEF BASELINE VALUES
A PEF measure with a high value usually means that your airflow is good.
The best way to determine what is a healthy PEF for you is to discuss this with your physician
or other licensed healthcare professional. The importance of any changes in airflow from
one measuring to the next depends upon
how much they are different from the baseline
value
you should reach when you are in healthy physical condition.
Your physician or other licensed healthcare professional will use one of two possible ways
to identify
your baseline value
. The first method adopts the
predicted value
calculated
according to the results of epidemiological studies of large groups of healthy subjects of your
same age, height, gender and origin. The second method adopts the
personal best value
you can reach when you are in the healthiest
physical condition.
The
MIR SMART ONE
app can calculate the PEF
predicted value,
i.e. the expected value for
healthy people, depending on age, height, gender, and origin.
MIR SMART ONE
app
calculate the predicted value endorsed by ATS (American Thoracic Society): PEF predicted
values are calculated according to
Knudson, R. J., Slatin R. C., Lebowitz, M. D., Burrows, B.,
The Maximal Expiratory Flow-Volume Curve
–
Normal Standards, Variability, and Effects of
Age, AM REV RESPIR DIS, 1976 113;587-600.
In this case, the predicted value becomes the baseline value for your treatment plan. If your
physician or other licensed healthcare professional prefers this method,
MIR
SMART ONE
app provides the calculation of the predicted PEF value.
It is important to know that these predicted values are average numbers for large groups of
people. You may have a higher PEF measure than the predicted value and you may not be
healthy. Or you may have a lower PEF than the average and be healthy.
