“…However, a previous study has shown that there is no significant difference in PcjCh between the left and right eye during pulmonary surgery [20], For routine evaluation of oxygen status arterial blood gas analysis is often used but this does not reflect peripheral oxygenation during hemodynamic crises, where informa tion about tissue oxygenation is important. PcjCh monitoring, on the other hand, gives information about oxygenation at the tissue level, and the conjunctival oxygen index has been shown to be a sensitive parameter during hypovolemia.…”

Conjunctival oxygen tension (PcjO₂) and routine cardiorespiratory parameters were measured in 8 patients during pulmonary surgery. In each patient we found a close relationship between PcjO₂ and arterial blood oxygen tension (PaO₂), and for all patients the correlation coefficient was 0.962. The mean values of the ratio between PcjO₂ and PaO₂ in each patient were ranging between 0.46 and 0.55. We conclude that PcjO₂ measurements represent a useful and reliable method for evaluation of peripheral oxygenation and perfusion during pulmonary surgery. Furthermore, the method has been found useful for estimation of arterial blood oxygen tension in hemodynamically stable patients during anesthesia.
