Considerations regarding prognosis include the following:

  • Variability of clinical severity, laboratory values, and outcome limits prognostic accuracy

  • Cardiac arrest, coma, metabolic acidosis, and high HbCO levels are associated with poor outcome

  • Abnormal CT or MRI findings are associated with persistent neurologic impairment

  • Neuropsychiatric testing may have prognostic efficacy in determining delayed sequelae
