How do you keep track of well your lungs are working?

ANSWER

A peak flow meter can let you know about any changes in your airways that may be a sign of worsening asthma. By taking daily peak flow readings, you can learn when to change medications to keep asthma under control. Your doctor can also use this information to adjust your treatment plan.
