  1. GOSE Glasgow Outcome Scale Extended; PETCO2 end-tidal carbon dioxide partial pressure; SBP systolic blood pressure; SD standard deviation; SpO2 oxygen saturation
  2. aP<0.05 compared to Group A; bP<0.05 compared to Group B
  3. c GOSE is used to assess outcomes of patients with brain damage and is divided into 8 levels. The higher the grade, the better the patient’s prognosis is
