4. Use Your Peak Flow Meter Every Day

Once you know what your personal best peak flow level is, you will be able to evaluate your breathing and intervene quickly if necessary. You may even be able to identify subtle changes in your breathing before you can feel them. By knowing what your best reading is, you will be able to take appropriate measures before you experience difficulty breathing, wheezing, coughing, or other asthma symptoms.

Taking immediate steps to relieve symptoms may prevent the progression to a full-blown asthma attack. Consult with your health care provider for specific instructions. Generally, you will need to intervene if your peak flow reading is less than 80% of your personal best.
