Values represent median (IQR)
MAP mean arterial blood pressure, ScvO2 central venous oxygen saturation, PaO2 partial pressure of arterial oxygen, PaCO2 partial pressure of arterial carbon dioxide
P values were calculated with the use of (a) Mann–Whitney U test and (b) Independent t-test. * Systemic hemodynamic variables were recorded at the time of study inclusion, simultaneously with the evaluation of the peripheral perfusion parameters
#Arterial blood gas analyses were recorded from the closer time of inclusion in the study
