Pressure-controlled versus volume-controlled ventilation during one-lung ventilation in elderly patients with poor pulmonary function

Objective: The aim was to investigate the effects of two different ventilatory strategies: Pressure-controlled ventilation (PCV) versus volume-controlled ventilation (VCV) in elderly patients with poor pulmonary function during one-lung ventilation (OLV). Patients and Methods: The patients were enrolled into the study having poor pulmonary function (forced expiratory volume in 1 s Results: Comparison of the VCV group and PCV group, PaO 2 and P(A-a)O 2 were higher and dead space to tidal volume was lower in the PCV group ( P P 2 of three points in postoperation, the duration of postoperative ventilation duration, intensive care duration of stay and the days stay in hospital after surgery. Conclusions: The use of PCV compared with VCV during OLV in elderly patients with poor pulmonary function has significant advantages of intraoperative and postoperative oxygenation and it might be a factor, which can beneficial to postoperative recovery.
