How To Establish Your Personal Best Peak Flow:
When your asthma is under control, record your peak flow twice daily for 2 weeks. Measure your peak flow at the same time of day, as peak flow is lowest in the early morning and highest between 12:00 noon and 5:00 PM. The highest number during those 2 weeks will be your personal best peak flow. Reestablish your personal best peak flow with new peak flow meters. Children need to reestablish their personal best peak flow every 6 months to allow for lung growth changes.
