Brief summary
The purpose of this study is to determine if the position of the anesthesia machine affects the ability of anesthesiologists to manage a crisis situation and perform critical tasks. Participants will be asked to manage a simulated crisis situation using a manikin in the operating room. The anesthesia machine will be positioned either in an "optimal" or "awkward" manner for the anesthesiologist. The session will be video recorded and then analysed for various outcomes that reflect the anesthesiologist's performance. Participants will also perform a critical task, bag-valve-mask ventilation, on a manikin with the anesthesia machine in the optimal and awkward positions. The effectiveness of ventilation in each position will be compared. The results of this study may have implications for patient safety.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Crisis performance | Measured during the crisis scenario, average time is 5 minutes | A composite performance score defined as the mean of standardized MEPA checklist score and standardized time to scenario completion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time metrics | Measured during the crisis scenario, average time is 5 minutes | Time from change in vital signs to intervention |
| Case management score | Measured during the crisis scenario, average time is 5 minutes | Performance of predefined key tasks in the treatment of the simulated crisis |
| Ergonomic/motor metrics | Measured during the crisis scenario, average time is 5 minutes | 1. Number of times the hand(s) cross the midline and touches the machine or equipment 2. Number of times the anesthesiologist makes an adjustment to optimize BVM ventilation attempts: 3. Total number of degrees the anesthesiologist's head turns during the scenario 4. Total distance the anesthesiologist's hand travels during the scenario |
| Workload measurement metrics | Questionnaire is completed after the participation in the crisis scenario is completed. The questionnaire will take an average of 10 minutes to complete. | National Aeronautics and Space Administration Task Load questionnaire |
| Minute ventilation | Measured during the crisis scenario, average time is 5 minutes | Measurement of the minute ventilation during performance of bag-valve-mask ventilation on a manikin with the anesthesia machine in both the preferred and non-preferred positions. |
