  1. Results of performance data for the different study groups in the three evaluations. Data in x = n and percentage of respective group size or in absolute numbers ± standard deviation.
  2. Time to start CPR in seconds. Compression without faults: adequate compression depth and correct chest well decompression. Significant differences between groups are indicated bold.
  3. Significant differences between time-points:
  4. * baseline = > 1 week: p < 0.0001; $ baseline = > 1 week: p = 0.0003; † baseline = > 1 week: p = 0.0089;
