Oxygenation and pulmonary hemodynamics during one-lung with Bain circuit ventilation in canine / 中华麻醉学杂志

To observe the oxygenation and pulmonary hemodynamic variation of one-lung ventilation (OLV) with Bain circuit in canine. Method:To use oxygen insufflation into the upper nonventilated lung with or with out Bain circuit during OLV fifteen dogs was studied in comparison with two-lung ventilation (TLV). Result: In the OLV dog without Bain circuit PaO_2 and SaO_2 significantly decreased, A-aDO_2, CcO_2- CaO_2 and Qs/Qt increased markedly(P
