Observations on Esophageal Temperature during Exercise in Asthmatic and Non-Asthmatic Subjects,
Abstract
We measured upper esophageal temperature during exercise and the subsequent pulmonary functional responses in eight asthmatic subjects and in six normal subjects who breathed air at cold and dry, ambient and body conditions. Asthmatic subjects developed the greatest obstruction following exercise with cold and dry air and no response to air at body conditions, while the normal subjects developed no obstruction in the post-exercise period with any of the three air conditions. Despite the divergent responses in the two groups, upper esophageal temperatures fell by the same magnitude below core values in both normal and asthmatic subjects, indicating that identical degrees of airway cooling occurred. We concluded that rather than having a defect in the ability to condition inspired air, asthmatic subjects are more responsive to the effects of incompletely conditioned air. (Author)
