Be sure to measure your peak flow at about the same time each day. Talk with your doctor about when the best time is to do it. Some people measure their peak flow twice a day, once when they first get up in the morning, and again in the evening. Others measure before and after they take their asthma medicine. You and your doctor can decide what is right for you.
