Exhaled air contains thousands of volatile components, usually in minute concentrations. These substances can be detected using specifically adapted mass spectrometry devices. This research is being conducted in close collaboration with ETH Zurich.
We have created a database with respiratory profiles of healthy subjects and patients with various pulmonary diseases such as COPD, cystic fibrosis and obstructive sleep apnea. The objective is to compare the respiratory profiles and determine if diseases can be diagnosed via exhaled air. This is especially significant for the development of new diagnostic tests. Breath analysis is safe and non-invasive, making it a highly attractive clinical test.
Breath analysis in healthy subjects
For this study, we are looking for male and female non-smokers, smokers and former smokers aged between 18 and 75. They should not be suffering from any known lung disease.
Included in the study is a free lung function test including an explanation of the findings. Afterwards, a breath analysis is performed and you must exhale into a mass spectrometer. (Total time: two appointments, each approximately 15 minutes)
The study is supported by the Swiss National Science Foundation.

Breath analysis in patients
We currently perform breath gas analyzes on patients with COPD, lung cancer, pulmonary fibrosis and obstructive sleep apnea.
