Fig. 2

Plots showing the interaction between chest compression depth and chest compression waveform on the six blood flows that were measured in these experiments. All data are reported as liters per compression. The number sign symbol indicates statistical significance (p < 0.05) between waveforms. The asterisk symbol indicates statistical significance (p < 0.05) between chest compression depths. The ampersand symbol indicates statistical significance (p < 0.05) for interactions between the chest compression depth and the compression release time. a Aortic flow, b IVC flow, c carotid flow, d jugular flow, e renal artery flow and f renal vein flow
