Design outcomes

Primary

Measure	Time frame
Chest compression depth, measured continously via the pc skillmeter software of the Resusci® Anne skillmeter	—

Secondary

Measure	Time frame
1. Quality of ECC defined as number of percent of adequately achieved compression depth, continously assesed via skillmeter pc 2. Time to measurable decay in chest compression depth, continously assesed via skillmeter pc 3. Frequency of chest compression, continously assesed via skillmeter pc 4. Correct recoiling of the manikin's chest, continously assesed via skillmeter pc 5. Heart rate/systolic blood pressure ratio reflecting physical strain, measured before and immediately after chest compression 6. BORG rate of perceived exertion measured at 2nd, 4th, 6th and 10th minute of chest compressions 7. Systolic and diastolic blood pressure, measured before and immediately after chest compression 8. Nine Hole Peg Test, measured before and immediately after chest compression	—
