Intraoperative real-time monitoring of ethylene measured by LPAS in patients undergoing off-pump coronary artery bypass surgery. a Example of continuous monitoring during of the entire operation. At t = 0 h the patient was connected to the sampling line; DT = diathermy electrocautery with high-frequency electric currents

(adapted from [67]). b An example of a grafting procedure. The high-resolution peaks are associated with ethylene induced by lipid peroxidation during the reperfusion events
