Outcome Measures
Primary Outcomes (1)
Fraction of subjects surviving with good neurologic outcome(modified Rankin Score (mRS) ≤ 3) at 90 days after out-of-hospital cardiac arrest.
at 90 days after out-of-hospital cardiac arrest
Secondary Outcomes (23)
Treatment Success: 1. proportion of subjects that can be therapeutically cooled to randomly allocated target temperature ±0.3°C (as measured by the temperature probe)
24 hours
Treatment Success: 2. proportion of time at randomly allocated target temperature ±0.3°C during first 24 hours after initiation of induction of hypothermia
24 hours
Treatment Success: 3. time to randomly allocated target temperature, from call to 911, sustained restoration of circulation and initiation of induction of hypothermia
26 hours
Treatment Success: 4. rate of cooling in °C per hour
Per hour
Treatment Success: 5. rate of rewarming in °C per hour

Eligibility Criteria
You may qualify if:
- Signed informed consent (obtained from their legal representative)
- years of age or older and less than 80 years old.
- Witnessed OHCA of presumed cardiac cause
- Sustained ROSC (when chest compressions have not been required for 20 consecutive minutes and signs of circulation persist)
- Initial shockable cardiac rhythm (documented by ECG or AED)
- Interval from collapse to advance life support \< 20 minutes
- Interval from collapse to ROSC \< 60 minutes
- Lack of meaningful response to verbal commands upon arrival to hospital after suffering non-traumatic cardiac arrest in an out-of-hospital setting
- Systolic blood pressure of \>90 maintained for a least 30 minutes post-ROSC without pressors, or with a stable dose of pressors
You may not qualify if:
- Traumatic cardiac arrest
- Toxicological etiology
- Known or suspected pregnancy
- Do Not Attempt to Resuscitate order in force
- Unwitnessed arrest
- In-Hospital arrest
- Anatomy, previous surgery or disease state contraindicating femoral venous access
- Received neuromuscular blocking agents prior to assessing level of consciousness following ROSC
- Neurological evaluation insufficient/incomplete after ROSC but prior to randomization.
- Body core temperature \< 34ºC at randomization
- Current Inferior Vena Cava (IVC) filter
- Known history of acute neurological illness or severe functional disabilities prior to arrest (e.g., seizures, traumatic brain injury, increased intracranial pressures, intra-cerebral hemorrhage, etc).
- Known hypersensitivity to hypothermia including a history of Raynaud's disease
- Suspected or confirmed acute intracranial bleeding
- Suspected or confirmed acute stroke
- +3 more criteria
