Design outcomes

Primary

Measure	Time frame
CoV (Center of Ventilation) in the EIT of the ventilated lung.	—

Secondary

Measure	Time frame
- Measurement of tidal variations (TIV) within the Regions of Interest (ROI) - Calculation of the GI (Global Inhomogeneity Index) in the EIT - paO2, paCO2, oxygenation index at defined measuring times - maximum intraoperative dose of norepinephrine in µg/kg bw/min) - Number of interventions in the LAMA group requiring secondary intubation (conversion rate to double lumen tube) and number of interventions requiring a change of procedure from DLT to laryngeal mask - postoperative pain level at the beginning and at discharge from the AWR/PACU, on the 1st POD, as well as at discharge from the hospital using NRS (pain) / recording of peaks and at rest - Rate of sore throat, hoarseness and difficulty swallowing using NRS 1-10 on discharge from the AWR, on the 1st POD, on discharge, on the 28th POD - perioperative process times in min (comparison of release time, release cut time, cut-suture time, suture to end of anaesthesia) -breathing frequency perioperative -OP conditions, assessment by surgery: NRS 1-10 - Percentage decrease in FEV1 and VC between preoperative evaluation of lung function (spirometry findings) preop. and at discharge - Frequency of pulmonary complications until discharge from the hospital and on the 28th postoperative day (type, number) -frequency of home oxygen therapy/LTOT supply preoperatively and on the 28th POD (in l/min, continuous or intermittent)	—
