Development and Testing of Screen-Based and Psychometric Instruments for Assessing Resident Performance in an Operating Room Simulator

Figure 3

Plot showing the changes to relevant parameters in the “hypovolemia” scenario. Near the beginning, heart rate gradually increases over 5 minutes but does not surpass the alarm threshold. Later in the scenario, a low blood pressure is measured and the appropriate alarm sound enunciated. All parameters normalize and revert back to baseline levels before the end of the scenario.
