Figure 1

The configuration of the simulator script. The angular grey boxes represent simulator states that are passed through automatically according to the fulfilling of the conditions (arrows). The round white boxes are the states that have to be marked by the observer ("marker state") as soon as their content is performed by the trainees. After each marker state, the simulator returns into the state "no chest compressions". The state "exit" permits full simulator control to the observer immediately. Abbreviations: ASY = asystole, CC = chest compression, CF-LV = contractility factor left ventricle, CF-RV = contractility factor right ventricle, CRO = cardiac rhythm override, cVF = coarse ventricular fibrillation, IIS, ischemic index sensitivity, LLV = left lung volume, pVT = pulseless ventricular tachycardia, SBP = systolic blood pressure, SR = sinus rhythm, t = time in state
