Airway Narrowing Measured by Spirometry and Impulse Oscillometry Following Room Temperature and Cold Temperature Exercise.

This article focuses on a study related to airway narrowing measured by spirometry and impulse oscillometry following room temperature and cold temperature exercise. The knowledge that respiratory symptoms alone do not predict the presence of exercise-induced bronchoconstriction (EIB) justifies the need for objective testing methods for diagnosis. EIB, a transient narrowing of the airways during or shortly following the termination of exercise in susceptible individuals, exceeds the estimated 10 to 12% prevalence of asthma in both the general population and in the elite athlete population. The symptoms and observable signs of EIB are varied and disparate in nature, commonly including cough, wheeze, dyspnea, chest tightness, and/or excess mucus.
