Cardiac Arrest (CA)
Conditions
Brief summary
The purpose of this study is to compare the effectiveness of two defibrillator pad placements, one where pads are placed on the front of the chest and back (anterior-posterior \[AP\]) and one where the pads are placed on the front and side of the chest (anterior-lateral \[AL\]), for the treatment of cardiac arrest. Both pad placement locations are recommended for use by the American Heart Association (AHA) and International Liaison Committee on Resuscitation (ILCOR) and are used in standard treatment. The investigators are hoping to find out if one pad position is more effective than the other in the treatment of cardiac arrest.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post-Shock Return of Spontaneous Circulation (ROSC) | day 1 | Any palpable pulse documented at any time after the first EMS shock |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to first rhythm analysis | day 1 | Time from EMS arrival on-scene for non-EMS witnessed arrests and first rhythm analysis by the defibrillator |
| Time to initial shock | day 1 | Time from EMS arrival on-scene for non-EMS witnessed arrests and initial shock by EMS |
| Total EMS shocks | day 1 | Total shocks given by EMS |
| Time to ROSC | day 1 | Time to ROSC from initial shock with competing risks (e.g. termination of resuscitation, pad change, double sequential external defibrillation use) |
| Survival to hospital admission | day 1 | Survival to hospital admission |
| Survival to hospital discharge | through study completion, an average of 7 days | Survival to hospital discharge |
| Survival to hospital discharge with favorable outcome | through study completion, an average of 7 days | Survival to hospital discharge with a Cerebral Performance Category score of 1-2 |
