Evaluation of Novel Lung Function Parameters in Patients With Bronchial Asthma

January 27, 2019 updated by: Dr. Frederik Trinkmann, Universitätsmedizin Mannheim
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.
