Diagnosing non-small cell lung cancer by exhaled-breath profiling using an electronic nose: a multicentre validation study.

Chest, 2022
BACKGROUND Despite the potential of exhaled-breath analysis of volatile organic compounds to diagnose lung cancer, clinical implementation has not been realized partly due to the lack of validation studies.

Octane in exhaled breath to diagnose acute respiratory distress syndrome in invasively ventilated intensive care unit patients

ERJ Open Research, 2023
Background The concentration of exhaled octane has been postulated as a reliable biomarker for acute respiratory distress syndrome (ARDS) using metabolomics analysis with gas chromatography and mass spectrometry (GC-MS). A point-of-care (POC) breath test

An Exhaled Breath Sampler Based on Condensational Growth and Cyclone Centrifugation (BSCC)

Aerosol and Air Quality Research, 2022
An exhaled breath sampler based on condensational growth and cyclone centrifugation (BSCC) was developed and evaluated. The BSCC increases the size of exhaled breath aerosols through condensational growth and then collects them as liquid sample via ...
