One-lung ventilation with capnothorax
Airway separation with unilateral lung closure (one-lung ventilation, OLV) is used to facilitate exposure during lung surgery and thoracoscopic surgery. In the latter case, insufflation of carbon dioxide may provide further optimization by compressing the lung. The respiration needs to be managed with one lung only and its related problem regarding CO2 elimination and oxygenation. There may also be a mismatch between perfusion and ventilation during OLV. There may be important hemodynamic side effects that require treatment. We have developed a model to explore the physiology during these conditions (1). The model has been used further to define the optimal conditions for this kind of ventilation and will be included in an upcoming doctoral thesis (Henrik Reinius)
