- Close your lips tightly around the mouthpiece.
- Breathe out as hard and as fast as you can for 1 or 2 seconds.

What is a normal FEV1?
The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65). When compared to the reference value, a lower measured value corresponds to a more severe lung abnormality.
Is 350 a good peak flow?
Peak expiratory flow (PEF) is measured in litres per minute. Normal adult peak flow scores range between around 400 and 700 litres per minute, although scores in older women can be lower and still be normal.
Are peak flow meters reusable?
The meter is a small reusable device, it measures your peak flow using light sensor technology and sends it to the app. It works with any smartphone and connects by the audio jack. We also provide lightning cable adaptors. No batteries or charging needed.
What is the cost for a peak flow meter?
Peak flow meters[1] can cost nothing (with insurance) or up to $100. Asthma specialty clinics often provide patients with a free peak flow meter, so patients can learn to manage their symptoms[2] with the meter.

Can I test my lungs at home?
A home lung function test uses a peak flow meter or a home spirometer to monitor and evaluate any breathing problems you may have on a day-to-day basis. A peak flow meter allows you to measure your peak expiratory flow. A home spirometer allows you to measure your forced expiratory volume at 1 second (FEV1).
Can I use a spirometer at home?
Most people who have asthma only take a spirometry (lung function test) occasionally, during a doctor’s appointment and monitor their lung condition at home with a peak flow meter. Now, however, it is possible to take a spirometry test at home, too.
What does 70 percent lung capacity mean?
This represents the percentage of your lung capacity that you can expel in one second. The higher your percentage, the larger your lung capacity and the healthier your lungs. Your doctor will diagnose COPD if your FEV1/FVC ratio falls below 70 percent of the predicted value.
What does 50% lung capacity mean?
If it is only half full, it is 50% full. And 33% means it is only one-third full, and so on. Likewise, if your FEV1 is 50%, your lungs are able to handle only half as much air as they should. If your FEV1 is 33%, your lungs are able to handle even less—only a third as much.
