Incidence of a low tissue oxygen saturation in a mixed population of critically ill patients
Critical Care volume 14, Article number: P151 (2010)
StO2 was measured on the thenar eminence (InSpectra StO2 Monitor Model 650; Hutchinson Technology) of all patients present in the ICU during 1 week. All patients were measured only once (on Monday when already admitted, or on the day of admission). Data are presented as mean ± SD unless otherwise specified.
Forty-one patients (age 53 ± 19 years; 63% males) were included. Fifty-nine percent of the patients were admitted following surgery. Median StO2 was 83% (IQR: 75 to 88) (Figure 1). No relationship was found between day of admission and measured StO2 (Figure 2). Thirty-one patients (76%) had StO2 below normal (Figure 2, top line). Twelve (29%) patients had StO2 ≤75% (Figure 2, dotted line). Seven patients had StO2 <70; mortality of these patients was 29% vs 9% in patients with StO2 >70% (NS).
The incidence of an abnormal StO2 in critically ill patients is high. Also very low StO2 values are frequently found and may be associated with increased mortality.
