Why Use a TruZone® Peak Flow Meter?

The TruZone® PFM is a "one size fits all" peak flow meter, meaning that one model can be used by either children or adults. The user can personalize the TruZone® PFM with the unique ColorZone® Tapes as recommended by the health care provider. These tapes help with the ongoing  management of asthma.

The TruZone® PFM measures the Peak Expiratory Flow ("PEF").  PEF is the fastest speed at which air is forced from the lungs after taking a deep breath. This measurement is useful in detecting changes in the airways that could signal a worsening of symptoms or an improvement in breathing function for people with respiratory conditions such as asthma or emphysema. Use of the Daily Record as instructed and sharing this information with the health care provider at each visit is part of the overall asthma management program.

Normal PEF numbers vary based on sex, age and height. The "personal best PEF" number is usually the highest PEF number that is recorded on the Daily Record sheet over 2-3 weeks. The "personal best PEF" number is the goal to reach when using the TruZone® PFM. The healthcare provider usually helps the patient in assessing the proper PEF targets as part of the Asthma Action Plan.

The PEF is normally measured at 8 A.M. and 8 P.M. However, the healthcare provider may recommend a different program. To ensure proper technique, the health care professional should observe the initial use of the TruZone® PFM.

Results recorded in the Daily Record will identify changes, trends or patterns in respiratory symptoms. The health care professional should always be contacted when changes in the PEF indicate a worsening condition.

TruZone® Peak Flow Meter and its accompanying literature meet the most recent Technical Standards of Spirometry for portable peak flow meters established by the American Thoracic Society. The TruZone® PFM meets the educational guidelines recommended by the National Asthma Education Prevention Program (NAEPP) of the National Institutes of Health.
