Fig. 3 — Plots showing the interaction between chest compression depth and chest compression waveform on blood pressures and EtCO₂ that were measured in these experiments. All data are reported as mmHg. The number sign symbol indicates statistical significance (p < 0.05) between waveforms. The ampersand 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 pressure, b right atrial pressure, c coronary perfusion pressure and d end tidal carbon dioxide
