, hypoxemia, and acid-base derangements during general anesthesia. 3 Matching of alveolar ventilation to pulmonary perfusion is critical for effective gas exchange and tissue oxygenation. However, in anesthetized horses, large areas of ventilation
oxygen at the level of the carina, reducing the oxygen flow rates necessary to achieve adequate oxygenation. 9 In hypoxemic foals, transtracheal catheter oxygenation resulted in more improvement of the arterial oxygen partial pressure (PaO 2 ) when
The s/ t is an OCI used to assess the degree to which venous blood is not fully oxygenated during its transit through the lung. 1,2 Fung disease, atelectasis, and high F io 2 s (> 0.7) can increase s/ t. 3 Calculation of s/ t is useful in the
deleterious for the cells lining the lungs. In addition, the appropriate duration and levels of blood oxygenation are unknown for HBO therapy in horses. Therefore, the purpose of the study reported here was primarily to assess the effects of HBO on the
saturation, complete dead-space wash out was proposed to have been achieved and increases in Pa o 2 were no longer evident. 31 When complete dead-space washout is achieved, the alveoli are filled with freshly oxygenated gas that does not contain residual
mm in diameter by use of wire mounts, and data were recorded digitally. c Rings were equilibrated in warmed, oxygenated Kreb solution for 30 minutes with < 1mN resting tension. After equilibration, the IPBs were contracted with 80mM KCl
