Average chest compression quality during the resuscitation (scatter plot). a, c Mean compression depth of the resuscitations. The points indicate one resuscitation each, where no correction of the compression depth was applied. A triangle mark shows the average compression depth of the resuscitation after the participant corrected the tutor. b, d Average compression rates. The triangle indicate that a correction of the compression rate has been applied and the average was calculated based on this correction. a Ethics: Median (Q25–Q75) 37.0 (31.0–39.0) mm; CRM: 34.0 (31.0–37.00 mm) b Ethics: 142.0 (137.0–145.0) bpm; CRM: 141.0 (137.25–146.75) bpm c Ethics: 36.0 (33.5–41.5) mm; CRM: 37.5 (33.0–54.25) mm d Ethics 143.0 (133.5–150.0) bpm; CRM: 137.5 (115.0–146.5) bpm
