Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | iA-CPR | Integrated Mechanical CPR with AutoPulse All subjects initially receive manual chest compressions. After randomization, subjects randomized to iA-CPR are moved to the device once it is ready and from thereon receive mechanical chest compressions.~AutoPulse: Mechanical device that provides chest compression | 196 | 2,094 | OG000 |
| Group 2 | M-CPR | Manual CPR All subjects initially receive manual chest compressions. After randomization, subjects randomized to M-CPR continue to receive manual chest compressions.~Manual: Manual chest compression | 233 | 2,125 | OG001 |
