The Peak Flow Meter: A classic at-home and clinical asthma monitoring.
This essential respiratory tool is made to accurately measure the speed of your exhalation, providing a clear indication of lung function. Its innovative design incorporates an internal one-way valve, esssential for preventing inadvertent inhalation through the device, a vital feature for multi-patient environments. To enhance hygiene and safety in clinical settings, the use of a disposable one-way valve mouthpiece is highly recommended, ensuring protection against cross-contamination.
The Peak Flow Meter is distinguished by its lightweight and compact form, making it highly convenient for on-the-go use. It can measure peak expiratory flow (PEF) ranging from 60 to 800L/min and comes in two scale variations, catering to different measurement needs. The standard range peak flow meter, featuring easily interpretable graduations, is ideal for adults with normal respiratory strength. Regular monitoring with this device aids in the early detection of potential asthma exacerbations, allowing for timely intervention and management.

16 Benefits of the Peak Flow Meter
What is a Peak Flow Meter used for?
Diagnosis and Measurement
The peak flow meter is a vital tool for individuals with asthma, measuring the effectiveness of air expulsion from the lungs. This device aids in both diagnosis and management of asthma. Users perform a peak flow test by forcefully exhaling into the meter, providing insights into their lung function. The resulting peak flow score helps identify narrowed airways, a common asthma symptom. While indicative, additional tests may be needed for a definitive diagnosis.
Monitoring and Management
For those already diagnosed with asthma, regular monitoring of peak flow readings is essential. These readings can reveal the progression of the condition, the effectiveness of medications, and even the onset of an asthma attack. By consistently tracking peak flow measurements, individuals can better manage their asthma and make informed decisions about their treatment plan in consultation with healthcare providers.
Identifying Triggers
Furthermore, measuring peak flow before and after exposure to potential triggers, such as allergens or workplace substances, can pinpoint specific factors exacerbating symptoms. This makes the peak flow meter an indispensable tool for asthma management and lifestyle adjustments. By identifying triggers, individuals can take proactive steps to avoid or minimize exposure to these factors, thereby reducing the frequency and severity of asthma symptoms.
How to use a Peak Flow Meter
Measuring your peak flow is a straightforward process, initially taught by a healthcare professional. Once you're familiar with the procedure, it's simple to perform regularly at home with your own peak flow meter. Here's how:
- Find a Comfortable Position: Start by sitting or standing comfortably – maintain this same posture each time you measure.
- Reset the Meter: Push the pointer back to the start of the scale near the mouthpiece.
- Hold the Meter Correctly: Ensure the peak flow meter is horizontal, and your fingers do not cover the measurement scale.
- Deep Inhalation: Take a deep breath in.
- Tight Lip Seal: Place your lips firmly around the mouthpiece.
- Exhale Forcefully: Blow out as quickly and forcefully as you can.
- Record Your Reading: After exhaling, note down the reading displayed.
- Repeat for Accuracy: Perform this process three times, recording the highest of the three readings as your peak flow score.
Your peak flow score, or peak expiratory flow (PEF), is measured in litres of air breathed out per minute (l/min). A 'normal' score varies based on age, height, and sex. For personalised benchmarks, consult your GP or asthma nurse.
In asthma diagnosis, your result is compared against expected norms for someone of your age, height, and sex. Variations in scores, especially noticeable differences between morning and evening readings or during symptom fluctuations, can indicate asthma.
For those monitoring asthma at home, compare your current score to your best score during well-controlled periods. Significant deviations may signal worsening control or an impending asthma attack. Keep a diary or chart to track these readings for effective asthma management.

When to Seek Medical Assistance
Understanding when to seek medical advice for your peak flow readings is crucial, particularly for individuals with asthma. Here are the key guidelines:
- Refer to Your Asthma Action Plan: If you have a personal asthma action plan, it should be your first point of reference when your peak flow score is lower than usual. This plan typically includes specific instructions on actions to take, such as using particular inhalers or contacting medical professionals.
- Consult a Healthcare Professional: If you're diagnosed with asthma but do not have a personal action plan, or if you're uncertain about your peak flow score and its implications, it's essential to contact your GP or asthma nurse for guidance.
- Develop a Personal Action Plan: During your medical appointment, you might be advised to develop a personal asthma action plan. Completing this plan with your doctor or nurse is vital, as it serves as a personalised guide for managing your asthma effectively.
- Annual Review and Update: Your asthma action plan should be reviewed and updated at least once a year. This review typically happens during your annual asthma consultation with a healthcare professional. It ensures your plan remains relevant to your current condition.
- Keep Your Plan Accessible: Always bring your asthma action plan to every medical appointment related to your asthma, including visits to A&E or consultations with specialists. This helps ensure any changes in your condition or treatment are promptly incorporated into your plan.
Remember, timely and appropriate responses to changes in your peak flow readings are integral to effective asthma management. If you have any concerns or questions about your readings or condition, do not hesitate to seek medical advice.
