We will perform in situ high-fidelity simulation of two critical children's emergency resuscitation scenarios using the current standard of care with existing cognitive aids.

We will perform in situ high-fidelity simulation of two critical children's emergency resuscitation scenarios using a linear cognitive aid

Key features of this tool include:

• Minimal input: Teams input the patient's age and clinical scenario (e.g. arrest, childbirth, or trauma).
• Linear logic: Based on initial simple input, the tool provides straightforward guidance without requiring multiple Y/N input or advanced decision-making.
• Guidance based on individual characteristics: The tool tailors AHA guidance for the specific emergency scenario to the individual patient's size (estimated by age), emphasizing key interventions for the individual scenario and giving appropriate size-based guidance regarding choice of equipment, medication dosage, and resuscitation technique (e.g., chest compression depth).
• Time-based and on-demand guidance: Based on the time elapsed from the start of the resuscitation, the app will provide audio guidance regarding the next key steps.

Time stamps for achieving completion of clinically recommended steps according to AHA guidance in minutes and seconds over a total 10 min simulation session. Less time taken is better performance.

Teamwork will be evaluated in real time using the validated Clinical Teamwork Scale (CTS™) over each 10 minute simulation. The scale ranges from 0 to 10, with 0 being "unacceptable" and 10 being "perfect."
