WHAT IS THE SCIENTIFIC BASIS FOR PEF AND FEV1 HOME MEASUREMENT?
The first portable mechanical meter to measure PEF was introduced in 1959 by B. Wright. The
widespread use of this device to monitor children
made it a popular means of tracking the degree of respiratory conditions in patients with asthma
and other pulmonary conditions.
Inexpensive, small, portable, and easy to use electronic meters for evaluating respiratory
conditions are now widely available. They offer several advantages including the ability to record
PEF and FEV1, and to store and transfer data to a physician or other licensed healthcare
professional.
SMART ONE provides a warning message if a test is not correctly performed, for example if instead
of blowing out as hard and fast as you can, you exhale too slowly. This is another clear advantage
compared to a mechanical peak flow meter that does not provide any message.
PEF and FEV1 are measured during the same exhalation. When the test is correctly performed, PEF
is measured 0.10–0.15 seconds after the blow start, while FEV1 is measured exactly 1.0 second
after the blow start.
According to best current evidence from several scientific studies, research paper topics and
clinical expertise, both PEF and FEV1 have proven to be good indicators of airflow function in
health and illness that can indicate how well you are breathing and can help you determine if
there are changes in your airflow. Regular measurements of PEF and FEV1 provide evidence of
disease progression.
The GUIDE FOR ASTHMA MANAGEMENT AND PREVENTION published in 2016 by GINA (Global
Strategy for Asthma Management and Prevention) states:
Effective asthma self–management education requires:
• Self–monitoring of symptoms and/or lung function
• Written asthma action plan
• Regular medical review
The above indicates that when engaged in self–management of asthma, your lung conditions can be
effectively monitored according with the written action plan prepared by a physician or a licensed
healthcare professional.
CAUTION: a physician's or other healthcare professional's advice is required to interpret the
meaning and importance of the measurements reported by smart one and how to decide on an
appropriate action plan
