Pulmonary function tests

The function of the lungs can be examined with several diagnostic procedures:

  • Spirometry measures dynamic lung function parametersimportant for the evaluation of obstructive diseases such as asthma or COPD.
  • Whole-body plethysmography can reliably determine the volume of the entire lung, which may be limited in restrictive diseases such as pulmonary fibrosis.
  • Fractional exhaled nitric oxide (FeNO) can be analyzed in a simple exhalation test. This parameter reflects the asthma-specific inflammation in the airways and can be elevated if therapy is not adequate. This allowsperfect adaptation of your asthma therapy.
  • Blood gas analysis reflects not only the function of the lungs, but also the complex interaction of respiration, the balance of acids and bases and kidneyfunction. With this test, an undersupply of oxygen can easilybe detected
