Why the study?
Does oxygen supplementation increase tissue oxygenation and prevent critical reduction in cerebral oxygenation in patients undergoing vascular surgery?
Does oxygen supplementation increase tissue oxygenation and prevent critical reduction in cerebral oxygenation in patients undergoing vascular surgery?
Oxygen supplementation increases cerebral and muscle oxygenation during vascular surgery, but critical reductions in cerebral oxygenation still occur and appear related to reduced cardiac output rather than hypotension.
No takes yet. Share an insight, caveat, or question.
May support preoxygenation in vascular surgery; hypothesis-generating for cardiac output over MAP to avert cerebral desaturation.
Rokamp et al. (2014) studied this question.
