From: A case requiring re-thoracotomy due to a significant reduction of tidal volume after commencement of chest tube drainage under pressure control ventilation following lower lobectomy

Fig. 3

The phenomenon happened after switching pressure control ventilation to volume control ventilation. The left side of the figure shows the lung state during PCV with drainage. The right side of the figure shows the lung state after switching PCV to VCV. In case of VCV, 450 ml of TV forced lung volume to increase from X + 450 ml to X + 450 + 450 ml, which increased plateau pressure to 24 cmH2O because of more increased elastance by more overextension. PEEP, positive end-expiratory pressure; Plateau Prs, plateau pressure; PCV, pressure control ventilation; VCV, volume control ventilation; IPP, intrapleural pressure; TPP, transpulmonary pressure
