Evaluation of Novel Lung Function Parameters in Patients With Bronchial Asthma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

Brief Summary:
Current guideline-based criteria defining bronchial asthma do not always meet the challenges set by the complex pathophysiology of the disease. The investigators therefore aimed to evaluate novel or not widely used functional diagnostic approaches for the detection and therapeutic monitoring of patients with asthma.

Condition or disease Intervention/treatment
Bronchial Asthma Pulmonary Healthy Controls Diagnostic Test: impulse oscillometry Diagnostic Test: multiple breath washout test Diagnostic Test: body plethysmography
