How to Optimize Volume Status Prior to Intubation

We do try to optimize volume status prior to initiation of triculantivation and the initiation of the intubation is the point at which these patients were screened. And all of them, we actually surveyed them in response to review too. So that may be in part an explanation for your, I think, important point that many of these patients we don't know,. We didn't collect data on this, but presumably at least some of them might have gotten fluids for another indication at some point in the period intubation period is certainly possible. But we can't speak to that really with the results of this study.
