Methods: We will videotape both good quality CPR and poor quality CPR in a simulated resuscitation. We will record 4 videos, one depicting high quality CPR, and 3 depicting the most common mistakes made when performing chest compressions, and these will be videotaped from the foot, head and side of the patient. Pediatric acute care professionals will be recruited to watch a randomized set of all 12 video clips, and fill out a brief and simple questionnaire on their assessment of the quality of the CPR being performed.
