Set red indicator to bottom of scale.
-
Stand up, take a deep breath, place your mouth around the peak flow meter and hold it horizontally, your lips form a tight seal.
-
Blow the air out as hard and as fast as possible. The number where indicator stops is your peak measurement.
Note: Coughing and spitting into the meter will adversely affect your reading and should be avoided. -
Repeat the steps 1, 2, 3 twice more to obtain three readings. Record the highest reading in your daily record chart.
Troubleshooting
Examine peak flow meter regularly to make sure it is working properly. The moving parts should function smoothly and freely and the indicator should remain in place when moved to a position of scale. If unusual readings are obtained, consult your doctor. Please contact Rossmax service if necessary.

Caution
Using a peak flow meter to monitor respiratory condition such as asthma should
be under the care of physician. A peak flow meter is intended for single-
patient use unless it is cleaned thoroughly after each use and disposable
mouthpieces are used. Mouthpieces are available.
How to record your peak expiratory flow rate
This meter was designed to make following your asthma treatment plan easy.
Your doctor will set the color zone indicators to your personalized zones
based on your personal best peak expiratory flow rate value (the best peak
flow value you can achieve).
Note: Do not change the position of the color zone indicators yourself. If this should occur inadvertently, contact your doctor or specialist nurse for advice. Reading should be taken twice a day, first in the morning and at bed time, or directed by your physician. When you blow into your peak flow meter, the indicator will rise to your peak flow value. Your peak flow measurement will fall into one of three zones.
- Green – Follow your regular medication plan, and go ahead with normal activities (80-100% of best reading).
- Yellow – Caution, your asthma might be worsening. Follow your medication instructions to get back to your green zone (50-80% of best reading).
- Red – Medical alert, get medical advice and attention immediately (< 50% of best reading).
