Introduction
A peak flow meter is a handheld device that measures how well air moves out of your lungs (peak expiratory flow rate). It is used to assess the severity and control of asthma. It is given to patients whose asthma symptoms are partially controlled or poorly controlled.
During an asthma episode, your airways often narrow. A peak flow meter can measure this narrowing hours, even days, before you have any asthma symptoms.
Use- Do’s
Place the indicator at the base of the numbered scale.
Stand up.
Take a deep breath.
Place the meter in your mouth between your teeth and close your lips around the mouthpiece.
Blow out as fast as you can in a single blow.
Write down the number you get. But if you cough as you use the meter or make a mistake, don’t use that number. Blow into the meter again and get a new reading.
Immediately repeat steps 1 through 6 two more times.
Write down the highest of the three numbers in your asthma diary.
After each measurement, make sure to reset the peak flow meter to zero before the next use. Failing to reset it can lead to inaccurate readings

Use- Don'ts
1. Do not obstruct or block the mouthpiece of the peak flow meter with your tongue, lips, or fingers when blowing into it.
- Ensure that the mouthpiece is clear and unobstructed before use.
2. Do not blow into the peak flow meter with excessive force, as this can lead to artificially high readings.
- Blow into the meter with a steady, but not forceful, effort to get an accurate measurement.
3. Avoid neglecting the regular cleaning and maintenance of the peak flow meter. A dirty or clogged meter may produce inaccurate results.
- Follow the manufacturer's instructions for cleaning and disinfecting the device.
4. Do not use a damaged or malfunctioning peak flow meter. Inspect the device regularly for cracks, broken parts, or other issues that may affect its accuracy.
- Replace the meter if it is damaged.
5. Avoid comparing peak flow readings obtained from different brands or models of peak flow meters. Different meters may have slightly different scales and calibrations.
6. Check the expiration date of your peak flow meter if applicable. Some meters may have a limited lifespan, and using an expired meter may result in inaccurate readings.
Recording
Your personal best peak flow number is the highest peak flow number you have over a two- to three-week period when your asthma is well controlled.
Well controlled asthma is when you experience minimal or no asthma symptoms such as coughing, wheezing, shortness of breath or chest tightness.
To find out your personal best peak flow number, take peak flow readings as recommended by your health navigator as applicable:
At least once a day for two to three weeks
When you wake up, between noon and 2 p.m.
Before and after taking quick-relief medicine
When you get a new peak flow meter, even if it is the same kind as you have used in the past
