Table 2 Levels of severity of illness and baseline resuscitation variables in 40 patients with severe community-acquired pneumonia according to basal brachioradialis muscle rSO2

From: The prognostic value of muscle regional oxygen saturation index in severe community-acquired pneumonia: a prospective observational study

Variable rSO2 < 60 % (n = 14) rSO2 ≥ 60 % (n = 26) p value

SOFA score, median (IQR 25–75) 4,5 (3–5,5) 4 (3–5) 0,73
MAP (mmHg), median (IQR 25–75) 84 (69,7–93) 75 (71,7–94,7) 0,64
SL (mM/L), mean (SD) 4,2 (4,8) 2,3 (1,5) 0,17
BD, mean (SD) −1,7 (6,7) −4,4 (3,9) 0,11
Catecholamines (μg/kg/min), mean (SD) 0,39 (1,5) 0,32 (0,32) 0,66
Fluid balance at 24 h (mL), mean (SD) 2130 (2200) 1450 (759) 0.18
Need for MV, n (%) 8 (57) 13 (50) 0,58
ICU mortality rate, n (%) 7 (50) 1 (3,8) 0,001
