- Primary Outcome Measures
Name Time Method Arterial blood oxygen pressure (PaO2). Timepoint: Before starting one-lung ventilation and for second time, 30 min after start of one-lung ventilation. Method of measurement: Arterial blood gas analysis.;Peak airway pressure. Timepoint: After tracheal intubation and then every 15 min during one-lung ventilation. Method of measurement: By airway pressure monitoring device included in anesthesia machine.;End-tidal pressure of CO2. Timepoint: Every 15 min during surgery. Method of measurement: By Capnograph monitoring.
- Secondary Outcome Measures
Name Time Method Dynamic compliance of respiratory system. Timepoint: After tracheal intubation and then every 15 min during one-lung ventilation. Method of measurement: Using the standard formula and tidal volume divided in airway pressure.;Respiratory dead space. Timepoint: After tracheal intubation and then 30 min after one-lung ventilation starting. Method of measurement: Calculation by the use of arterial and end tidal PCo2 pressure.
