Abstract In asthma elevated rates of exhaled breath temperature changes Ae T and bronchial blood flow Qaw may be due to increased vascularity of the airway mucosa as a result of inflammation. We investigated the relationship of Ae T with Qaw and airway inflammation as assessed by exhaled nitric oxide NO . We also studied the anti-inflammatory and vasoactive effects of inhaled corticosteroid and P2-agonist. Ae T was confirmed to be elevated A C s in 19 asthmatic subjects mean age SEM 40 6 yr 6 male FEV1 74 6 predicted compared to 16 normal volunteers A C s p 30 2 yr and was significantly increased after salbutamol inhalation in normal subjects A C s p but not in asthmatic patients. Qaw measured using an acetylene dilution method was also elevated in patients with asthma compared to normal subjects and pl ml min p and correlated with exhaled NO r p and Ae T r p . In asthma patients Qaw was reduced 30 minutes after the
