NCT07451730

Brief Summary

In this randomized crossover trial, participants begin with chest compressions at a 30:2 ratio while a study team member provides ventilation. In Scenario A, participants perform two-person CPR and receive a prerecorded patient history after 30 seconds. In Scenario B, participants only listen to the patient's history without performing CPR or any concurrent task. To control for time-dependent memory decay, Scenario B includes a 3-minute delay before completing the questionnaire, matching the interval between information exposure and recall in Scenario A. After each scenario, participants complete the NASA-TLX workload assessment and a semi-open questionnaire on the patient's history. A modified Brown-Peterson task follows as a washout period: participants subtract 3 repeatedly from 309 for 1 minute, followed by 4 minutes of rest without phone use or conversation. Calculation performance is not analyzed.
