Clinical Trial: The Effect of a Cold Air Eucapnic Hyperventilation Test on Lower Respiratory Airways in Healthy Volunteers and Patients With Asthma

U.S., Oct. 25 -- ClinicalTrials.gov registry received information related to the study (NCT07220928) titled 'The Effect of a Cold Air Eucapnic Hyperventilation Test on Lower Respiratory Airways in Healthy Volunteers and Patients With Asthma' on Oct. 23.

Brief Summary: In this study, we want to evaluate the feasibility and safety of a CAEH test in healthy volunteers and patients with asthma. We want to develop a CAEH test to differentiate patients with different types of asthma and exercise-induced bronchoconstriction from healthy volunteers and to evaluate whether the respiratory phenotype induced by cold air inhalation differs between subjects with asthma and healthy subjects. Furthermore, we want to evaluate whether the CAEH test is more...
