Before collection of exhaled air patients lungs were washed for 5 minutes with filtered air. Exhaled breath samples were collected on termodesorbtion tubes and later analyzed on gas chromatograph / mass spectrometer.Results: Mean concentrations of VOCs are shown in the table.p\<0,05: * compared to healthy controls95\% CI {\textendash} 95\% confidence interval of mean valueConclusions: Exhaled air of lung cancer patients contain less amounts of light spirits and hydrocarbons, compared to controls. VOCs spectrum from patients with lung inflammatory diseases doesn{\textquoteright}t differ significantly from normal controls.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/PP133}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/PP133.full.pdf}, journal = {European Respiratory Journal} }
