Real-time ventilation and perfusion distributions by electrical impedance tomography during one-lung ventilation with capnothorax

摘要

BackgroundCarbon dioxide insufflation into the pleural cavity, capnothorax, with one-lung ventilation (OLV) may entail respiratory and hemodynamic impairments. We investigated the online physiological effects of OLV/capnothorax by electrical impedance tomography (EIT) in a porcine model mimicking the clinical setting.
