See: http://www.users.globalnet.co.uk/~aair/asthma_PEF.htm Typical Peak Flow Chart [adjusted for age, height, sex] For diagnosing asthma, the important consideration is the variability of peak flow. Minimum is usually first thing in the morning before bronchodilator; maximum is usually midafternoon after bronchodilator. Variations of 20% tend to indicate the possibility of asthma. Patients need to establish their ‘personal best’ reading; then maintain in the 80-100% region using asthma drugs and other treatment. Ellis
