- The duration of the scenario was 300 seconds. Values are the mean ± standard deviation. The Philips HS1 asks the rescuer to press an “info button” for detailed information about chest compressions and ventilations after each rhythm analysis. The scenario was run 3 times when pressing the info button§ and 3 times without pressing the button*. A lack of statistical significance (p > 0.01) in comparison with a specific model is indicated by the identifying letter (A) – (I). +p < 0.01 against the respective parameter in the scenarios with an optimized sequence of actions.
