Cardiac arrest in the operating room is a rare but potentially catastrophic event with mortality rates greater than 50%. Recent CPR guidelines published by the American Heart Association (AHA) and the Heart and Stroke Foundation of Canada (HSFC) describe how high quality CPR improves survival rates and neurological outcomes from cardiac arrest. Despite CPR training, adherence rates with performance guidelines are alarmingly low in many pediatric hospitals . In addition to performance errors, medication errors have been reported to be as high as 50% during cardiopulmonary arrest. This can be attributed to many factors, including distractions and poor communication among team members. Previous studies suggested that loud noise in the operating room caused poor communication and impaired surgical performance. To understand more about simulation awareness during peri-operative cardiac arrest, the investigators are planning on conducting a prospective observational study, using a simulated perioperative cardiac arrest scenario in pediatric hospital.The investigators are aiming for a convenient sample of 20 simulation sessions. Each session will have a team of CPR providers (2 participants and 4 confederates). The 2 participants will include one anesthesiologist and one operating room nurse. The participants will be randomized into two group; group A will work in a noise environment of 85 dBA ( as per recommendation by the National Institute for Occupational Safety and Health (NIOSH), and group B will work in a noise environment of 100 dBA. Participants will be wearing eye tracking devices during the scenario (Tobii Pro GlassesTM) designed to capture areas of interest (AOI) / visual fixation. The investigators hypothesize that CC and medication errors are frequently left undetected and uncorrected, and that the less noise distractions during resuscitation improves but does not eliminate this pattern of inattentional blindness in resuscitation teams during simulated perioperative pediatric cardiac arrest. They also hypothesize that "look but not act" events are a frequent occurrence during simulated pediatric cardiac arrest, and that healthcare providers will have varying reasons that explain the occurrence of "look but not act" events.
