case_images: In the operative field, the left (dependent) lung contracted rapidly and its expansion was severely interrupted (Figure 1).
case_images: Changes of vital signs and ventilator settings in case  1. TV, tidal volume; PIP, peak inspiratory pressure; EtCO2, end-tidal carbon dioxide; MAP, mean arterial pressure; OLV, one-lung ventilation; DLV, double-lung ventilation.

case_images: Although SpO2 was maintained at 98% with 50% oxygen, end-tidal CO2 (EtCO2) and PIP increased from 38 to 40 mmHg and 20 to 23 cmH2O, respectively (Figure 2).
