How Does Activ8rlives SmartOne Peak Flow Work?
The Activ8rlives SmartOne Peak Flow and FEV
1
meter is a non-invasive method allowing the
monitoring of the Peak Expiratory Flow (PEF), also called Peak Expiratory Flow Rate (PEFR), which
is a person’s maximum speed of expiration. FEV
1
is also measured and is the volume of air
expelled during the first second of the same exhalation.
The
Activ8rlives SmartOne Peak Flow meter is a small, hand-held device used to monitor a
person’s ability to breathe out air. It measures the airflow through the bronchi of the lungs and
can be used to estimate the degree of obstruction in the airways. When there is an episode of
obstruction the air cannot generally be expelled as forcefully as possible, so your PEF and FEV
1
will be lower.
Peak Flow readings are higher when we are well, and lower when the airways are constricted.
From changes in recorded values, we may determine lung functionality, severity of Asthma or
other respiratory symptoms and treatment, and how well our treatment is working.
Measurement of PEF requires some practise to correctly use a meter and the normal expected
value depends on a patient’s gender, age and height. It is classically reduced in lung disorders
such as Asthma, COPD, Bronchiectasis or Cystic Fibrosis.
Due to the wide range of
Normal values and high degree of variability, peak flow is not the
recommended test to identify respiratory disease. However, it can be useful in some
circumstances to monitor the severity of it or efficacy of treatment.
It is important to use the same peak flow meter every time to ensure consistency of the
readings.
It is generally recommended to take one measurement in the morning and one in the evening,
every day, before inhaling your prescribed medication. Also it is advisable to carry out
additional measurements whenever you feel unwell or have a perceived shortness of breath.
The highest peak flow value is the measurement of interest. Repeat your measurement three
times to get the best possible result for the moment. Take care to have sufficient relaxation
between measurements.
The
Normal value (Target value) for PEF varies according to gender age and height. The chart
on page 12 of this manual can be used to read-off your Normal value. This is calculated for you
automatically in Activ8rlives. Enter this value in your Target PEF when registering for your Free

If in doubt, contact your Doctor or Respiratory Nurse for advice.
