Urine output is associated with survival.

<p>The urine output of the patients with a sustained ROSC (A) in the ED and (B) during the first 24 hours of the ICU stay (Spearman’s rank correlation test). Urine output was significantly increased in proportion to the magnitude of the fluid challenge (A) during ED resuscitation (p<0.001, r = 0.86) and (B) in the first 24 hours of the ICU stay in the patients who survived until discharge (p = 0.002, r = 0.81). However, in the patients who died during the hospital stay, (A) urine output did not significantly increase in proportion to the amount of fluid that was administered during the initial ED resuscitation period (B) but did increase during the first 24 hours of the ICU stay when the total fluid administered was ≤6000 ml. ^aThe number of patients with missing urine output information.
