The American Lung Association says: "A "normal" peak flow rate is based on a person's age, height, sex and race. A standardized "normal" may be obtained from a chart comparing the person with asthma to a population without breathing problems.
A patient can figure out what is normal for them, based on their own peak flow rate. Therefore, it is important for you and your healthcare provider to discuss what is considered "normal" for you.
Once you have learned your usual and expected peak flow rate, you will be able to better recognize changes or trends in your asthma."
