The module Spiroergometry is used to document spiroergometry examinations. The cardiopulmonary exercise test analyses the reactions and the interplay of the heart, circulation, breathing and metabolism during gradually increasing exercise, both in terms of qualitative and quantitative measures.
The examinations ought to be performed according to DZHK-SOP-K-07 .
