Right ventricular function during one-lung ventilation: effects of pressure-controlled and volume-controlled ventilation.

Objectives: To test the effects of pressure-controlled (PCV) and volume-controlled (VCV) ventilation during one-lung ventilation (OLV) for thoracic surgery on right ventricular (RV) function.

Design: A prospective, randomized, double-blind, controlled, crossover study.

Setting: A single university hospital.
