Data are expressed as mean ± standard deviation (SD).

PEEP, Positive end-expiratory pressure; AIx, augmentation index; Ti, time to inflection point; LVET, Left Ventricular Ejection Time; DT, Diastolic time; SEVR, diastolic AUC divided by systolic-AUC (Buckberg index); PP, Pulse pressure; AP, Augmentation pressure; MSBP, Mean systolic blood pressure; MDBP, Mean diastolic blood pressure; ms: milliseconds.
