Non-invasive Diagnosis of Pulmonary Embolism by Use of Biomarkers in Exhaled Breath Condensate

"New method for diagnosis of pulmonary embolism (PE) in order to validate/consolidate 151 putative identified biomarkers for PE in the exhaled breath condensate (EBC).~The EBC will be collected by use of the RTube(R) system which has been used in previous studies of EBC. As the patient breathes through a mouth piece, the exhaled breath is led through a cooling chamber where the vaporous part of the exhaled breath condenses.~We aim at collecting a total minimum of 3.0 mL EBC per study subject in order to have a sufficient amount of protein for the subsequent analysis. We aim at collecting exhaled breath condensate for 2\*15 minutes with the possibility to stop the collection after less than 15 minutes if the volume is sufficient."
