Research Paper



To measure exhaled breath temperature in patients with cystic fibrosis.


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.


Patients with cystic fibrosis showed no significant difference in plateau temperature [34.4(32.3–34.6) versus 33.9 (33.0–34.4)°C; P=0.35] while mean (SEM.) rate of temperature rise was significantly less in patients [0.09 (0.01) versus 0.14 (0.02) Δ°C/s ; P=0.04] as compared to controls.


There was a slower rise of exhaled breath temperature in patients with cystic fibrosis whereas plateau temperature was not significantly different from controls.
