Abstract
Objective: To measure exhaled breath temperature in patients with cystic fibrosis. Methods:
17 patients (6-18 years) with cystic fibrosis and 15 age- and gender-matched healthy controls
were recruited in this cross sectional study. Exhaled breath temperature was measured in
subjects recruited in both the groups with a device X-halo and analyzed as plateau
temperature achieved and rate of temperature rise. Results: Patients with cystic fibrosis
showed no significant difference in plateau temperature [34.4(32.3-34.6) versus 33.9 (33.0-
34.4)oC; P=0.35] while mean (SEM.) rate of temperature rise was significantly less in patients
[0.09 (0.01) versus 0.14 (0.02) ΔºC/s ; P=0.04] as compared to controls. Conclusion: There
was a slower rise of exhaled breath temperature in patients with cystic fibrosis whereas
plateau temperature was not significantly different from controls.
