Carbon dioxide dynamics in relation to neurological outcome in resuscitated out-of-hospital cardiac arrest patients: an exploratory Target Temperature Management Trial substudy.

When analyzed separately in univariable logistic regression models, maximum PaCO 2 as well as lowest pH showed highly significant associations with poor neurological outcome (OR 1.17, 95% CI 1.06–1.28; P < 0.001 and 0.03, 95% CI 0.01–0.09; P < 0.001, respectively).
