One-lung ventilation (OLV) is the isolation and selective ventilation of one lung field. OLV allows the collapse of lung lobes on the side of the thoracic surgical approach to facilitate observation of intrathoracic structures and to achieve lung immobility. OLV be achieved by endotracheal intubation with double lumen tubes or bronchial blockers. In this study, cardiopulmonary consequences of two-lung ventilation (TLV), OLV and Re-TLV (TLV after OLV) were evaluated in 5 dogs. The dogs were anesthetized with mask induction and maintained with isoflurane in oxygen. Tidal volume and respiratory rates were set to maintain end-tidal CO₂ at 40±2 mmHg during instrumentation.
