Supplementary Table S2: Absolute changes in cardiopulmonary hemodynamics following sternotomy and pericardiotomy

Absolute differences in cardiopulmonary variables at baseline with closed cest and closed pericardium to conditions after sternotomy with open chest but closed pericardium and after pericardiotomy with open chest and open pericardium. Data are presented as mean±SD or median [interquartile range] where appropriate. Groups are compared with one-way ANOVA or Friedman test with Turkey’s or Dunn’s multiple comparison post-hoc test where appropriate. Statistical analyses were performed on the absolute values and not on the differences. n=7 for all unless stated otherwise. <br> Abbreviations: MAP, mean arterial pressure; RV, right ventricular; CO, cardiac output; SV, stroke volume; mPAP, mean pulmonary arterial pressure; CVP, central venous pressure; PCWP, pulmonary capillary wedge pressure; PVR, pulmonary vascular resistance; SVR, systemic vascular resistance; PaCO2, partial pressure of arterial CO2; PaO2, partial pressure of arterial O2; FiO2, fraction of inhaled O2; PvCO2, partial pressure of mixed venous CO2; PvO2, partial pressure of mixed venous O2; EtCO2, end-tidal CO2; Ppeak, peak airway pressure; Pmean, mean airway pressure; LV, left ventricular; ESP, end-systolic pressure; EDP, end-diastolic pressure; ESV, end-systolic volume; EDV, end-diastolic volume; EF, ejection fraction; Ea, arterial elastance; SW, stroke work; dP/dt, derivative of pressure over time; Ees, end-systolic elastance; Eed, end-diastolic elastance; PRSW, preload recruitable stroke work; PVA, pressure-volume area. <br>
