This article studies the method for manipulating peak flow measurements producing falsely raised readings. Peak flow measurement is used in asthma management. The study determined if this technique could repeatedly produce clinically significant changes in peak flow readings. Fifteen adults, using a mini-Wright peak flow meter, made five measurements using the correct technique followed by five manipulated measurements under observation. Clinicians should be aware that patients might employ this technique to manipulate measurements which could have consequences for management.
