Medi Peak Flow Meters are handheld portable devices intended to measure peak expiratory flow as a means of monitoring respiratory conditions such as asthma. What is a Peak Flow Meter?
What is a Peak Flow Meter?
Peak Flow Meter is a small handheld device that measures a patient’s ‘Peak Expiratory Flow’ or ‘PEF’, a measure of how quickly a patient can forcefully exhale after full inhalation. It is important that patients consult their Clinicians/Specialist Nurses about what their personal best PEF is or should be, to provide a point of reference for tracking.
Why should Peak Flow be measured?
Upon diagnosis, clinicians should educate patients in self-management of their asthma and chart an Action Plan to also include a Peak Flow Meter. Patients over five years of age will benefit from regular monitoring of their PEF with a Peak Flow Meter; this determines how open the airways are at any given moment and helps in asthma management. Clinicians aim to keep patient’s Peak Flow stable ie with little difference between the morning and evening readings and from day to day. It is a useful patient guide for:
- When to seek emergency medical care
- When to stop or adjust medication
- What triggers the patient’s asthma attacks
