  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Number of Patients Who Survived to Hospital Discharge With Favorable Neurologic Function Defined as MRS Score <=3   [ Time Frame: When the subject is discharged from the hospital; an average of 12 days after cardiac arrest for subjects surviving to hospital discharge ]

2.  Secondary:   Major Adverse Event Rate as Measured by Number of Adverse Events   [ Time Frame: Time from cardiac arrest through hospital discharge (an average of 12 days for subjects surviving to hospital discharge ]

3.  Secondary:   Return of Spontaneous Circulation (ROSC)   [ Time Frame: Time of cardiac arrest until discontinuation of efforts ]

4.  Secondary:   Survival to Hospital (e.g., Intensive Care Unit) Admission   [ Time Frame: Time of hospital admission, up to 1 day after cardiac arrest ]

5.  Secondary:   Survival to 24 Hours   [ Time Frame: 24 hours following cardiac arrest ]

6.  Secondary:   Survival to Hospital Discharge   [ Time Frame: cardiac arrest to hospital discharge ]

7.  Secondary:   Survival to 90 Days   [ Time Frame: 90 days following cardiac arrest ]

8.  Secondary:   Survival to 365 Days   [ Time Frame: 365 days following cardiac arrest ]

9.  Secondary:   Neurological Recovery at Hospital Discharge, 30 Days, 90 Days, and 1 Year [Measured by Cerebral Performance Category (CPC), Overall Performance Category (OPC), and Health Utilities Index Mark 3 (HUI3); Cognitive Abilities Screening Instrument (CASI)]   [ Time Frame: Various: hospital discharge through 1-year survival ]
