Factors associated with a good outcome:
(1) cardiac arrest associated with an acute myocardial infarction
(2) cardiac arrest lasting < 5 minutes
(3) duration of CPR < 5 minutes
(4) pupils miotic (constricted) during CPR
Factors associated with a poor outcome:
(1) Glasgow coma score (GCS) < 9 on the third day after the arrest
(2) abnormal signs of neurological activity on the third day after the arrest
(3) generalized or focal seizures during the first 3 days after the arrest
(4) plasma osmolality > 320 mOsm per kg water
(5) presence of comorbid conditions
(5a) presence of hyperglycemia (blood glucose > 200 mg/dL)
(5b) uremia
(5c) hemodynamic instability with periods of hypotension
(5d) fever
