Overview
A peak flow meter is one of the most clinically useful tools available to someone managing asthma at home. It measures peak expiratory flow rate — the maximum speed at which you can force air out of the lungs — in a single, quick breath. This number is a reliable proxy for how open or constricted the airways are at the time of measurement, and tracking it consistently over time gives both the patient and their GP or asthma nurse a clear, objective picture of how well asthma is controlled and how it changes in response to triggers, treatment adjustments, or seasonal factors.
The Aerease Peak Flow Meter covers the standard adult and older child range of peak flow measurements. It is lightweight, portable, and straightforward to use — place the mouthpiece, take a deep breath, and blow as hard and fast as possible. The indicator on the meter shows the reading, which is then recorded in a peak flow diary. The process takes seconds, it can be done at home, at work, or while travelling, and it requires no batteries or calibration between uses. Regular peak flow monitoring — typically twice daily at the same times each day — generates the pattern data that asthma management guidelines recommend for tracking control and identifying early signs of deterioration before symptoms become severe.
If you have been prescribed or recommended a peak flow meter by your GP, asthma nurse, or pharmacist, the Aerease standard range meter is a reliable, affordable option for everyday home monitoring. It should be used in conjunction with a written asthma action plan provided by your healthcare team, which will specify the readings at which you should adjust your treatment or seek urgent medical advice.

How to Use the Aerease Peak Flow Meter
- Set the indicator to zero. Before each use, slide the indicator or cursor to the lowest position on the scale — this is the starting position for every measurement. If the indicator is not reset to zero before blowing, the reading will be artificially elevated by the previous measurement.
- Stand or sit upright. Take your reading in a consistent position each time — standing is generally preferred as it allows full lung expansion. Avoid lying down or slouching during measurement, as body position affects the reading.
- Take a deep breath in. Breathe in as deeply and fully as possible, filling your lungs completely. This gives you the maximum available airflow for the forced exhalation that the meter measures.
- Place the mouthpiece in your mouth. Close your lips firmly around the mouthpiece, creating a complete seal. Keep your tongue away from the opening and ensure your hands do not block the vents on the meter.
- Blow out as hard and as fast as possible. The key is maximum force and speed at the start of the breath, not a prolonged exhalation. The peak flow measurement is captured in the first fraction of a second of the blow — a long, slow breath out will not give an accurate result. Blow as if you are trying to blow out all the candles on a birthday cake in one go.
- Read and record the result. Note the number indicated on the scale and write it in your peak flow diary with the date and time. Do not remove the meter from your mouth before reading the measurement.
- Repeat three times and record the best of the three readings. Taking three consecutive measurements is standard practice — slight variation between blows is normal, and the best (highest) of the three readings is used as your result for that session.
- Reset to zero before each blow. Always reset the indicator to zero before each of the three attempts, not just before the first.
- Clean the mouthpiece regularly. Rinse the mouthpiece with clean water and allow to air dry. Do not immerse the meter body in water. Clean frequency should follow the manufacturer's guidance — NOT FOUND, please confirm from product documentation.
When to take peak flow readings
- Twice daily as a minimum for regular asthma monitoring — typically first thing in the morning before any inhalers, and in the evening. Morning readings tend to be at their lowest and are the most clinically informative.
- During or after exposure to a known asthma trigger, to assess the impact on airway function.
- When symptoms change — increased wheeze, tightness, or shortness of breath — to determine the degree of airway obstruction.
- As directed by your GP, asthma nurse, or written asthma action plan.
If you are unsure how to use a peak flow meter correctly or need help interpreting your readings, speak to a Pearl Chemist Group pharmacist or your asthma nurse for practical, reassuring guidance.

How to Store the Aerease Peak Flow Meter
- General storage: Store the peak flow meter in a clean, dry location away from direct sunlight and extremes of temperature. A bathroom cabinet is common but the humidity from showers can affect some meter materials over time — a bedroom or living room is a better long-term storage location.
- Mouthpiece: Keep the mouthpiece clean and store in a clean, dust-free environment — a small zip-lock bag or the original packaging works well. Rinse with clean water regularly and allow to air dry completely before storing or replacing on the meter.
- Transport: The meter is portable and can be carried in a bag or pocket when needed away from home. Avoid storing it where it can be knocked or dropped repeatedly, as impact damage can affect the indicator mechanism and calibration.
- Do not immerse the meter body in water. Clean the mouthpiece only — the main meter body should be wiped with a clean, slightly damp cloth if needed, not submerged or placed under running water.
- Replace periodically. NOT FOUND — please confirm the recommended replacement interval from product documentation. Peak flow meters should be replaced if they are physically damaged, if the indicator does not reset smoothly to zero, or if readings appear inconsistent with symptoms over time. Many asthma guidelines recommend replacing annually with regular daily use.
- Keep out of reach of children when not in supervised use.

FAQs
What is a peak flow meter and why should I use one?
A peak flow meter measures how fast you can blow air out of your lungs — called your peak expiratory flow rate (PEFR). This measurement reflects how open or narrow your airways are at the time of the blow, making it a simple but reliable indicator of airway function. For people with asthma, regular peak flow monitoring at the same times each day provides objective data that helps you and your healthcare team identify when your asthma is well controlled, when it is deteriorating, and how quickly it changes in response to triggers or treatments. It is one of the key tools recommended in asthma management guidelines precisely because it gives information that symptoms alone cannot always provide — airways can be significantly narrowed before breathlessness or wheeze becomes noticeable.
What is my personal best peak flow and why does it matter?
Your personal best peak flow is the highest reading you can achieve when your asthma is well controlled and your airways are as open as they can be. This figure is the baseline against which all subsequent readings are compared. Asthma action plans use your personal best rather than predicted values because individual variation in peak flow is significant — two people of the same age, sex, and height may have quite different personal best readings, and using the correct personal reference point makes the action plan thresholds meaningful for you specifically. Your GP or asthma nurse will help you establish your personal best after a period of good control, and this should be reviewed periodically as it can change over time.
When should a peak flow reading prompt me to seek urgent medical help?
Follow the red zone guidance in your written asthma action plan — typically a reading below 50% of your personal best indicates a severe asthma attack requiring urgent treatment and possibly emergency care. If your reading falls below the threshold specified in your plan despite using your reliever inhaler, seek urgent medical help or call 999. If you do not have a written asthma action plan, ask your GP or asthma nurse to provide one — it is an essential tool for safe self-management of asthma. If your peak flow is too low to give a reliable reading and you are significantly breathless, do not delay to measure — call 999 immediately.
My peak flow readings vary a lot between morning and evening. Is this normal?
A degree of variation between morning and evening peak flow is completely normal and is one of the characteristic features of asthma. Morning readings tend to be lower than evening readings because airway tone follows a circadian rhythm, and the early morning is when airways are typically at their most constricted. The size of the variation matters clinically — a diurnal variation of more than 20% between the lowest and highest readings of the day is generally considered significant in asthma management. Tracking this variation over time and sharing your peak flow diary with your asthma nurse or GP gives them important information about how well your asthma is controlled throughout the day.
How do I know the standard range meter is suitable for me?
The standard range peak flow meter covers the measurement range used by most adults and older children with asthma. If your readings consistently fall at the very bottom of the scale or cannot be reliably captured on a standard range meter, a low-range meter designed for lower flow rates — often used for young children or those with very severe airway obstruction — may be more appropriate. Your GP or asthma nurse will advise on the correct meter type for your lung function. NOT FOUND — please confirm the precise measurement range in litres per minute for the Aerease standard range meter from product documentation and include it here.
Do I need to replace the meter regularly?
Yes. Peak flow meters can become less accurate over time with regular use, particularly if the indicator mechanism becomes worn or if the meter has been dropped or damaged. Many asthma management guidelines recommend replacing the meter annually for patients who use it twice daily as part of ongoing asthma monitoring, or sooner if readings appear inconsistent, the indicator does not reset smoothly to zero, or the meter is physically damaged. Using a worn or inaccurate meter risks making clinical decisions based on unreliable data, which can either lead to undertreating a deteriorating situation or causing unnecessary alarm about readings that do not reflect true airway function. NOT FOUND — please confirm recommended replacement interval from Aerease product documentation.
