Clinical Evaluation of Subcutaneous Lactate Measurement in Patients after Major Cardiac Surgery
Figure 1
(a) Clinical evaluation of absolute lactate levels from
subcutaneous adipose tissue (satLAC)
on the -axis versus reference measurements from arterial blood (artLAC) on the -axis. Clinical lactate
grid as described in the method section is indicated as hatched areas. (b) 6-hour lactate trend analysis with respective clinically
acceptable and unacceptable ranges as described in the method section. Relative
6-hour lactate trend of reference arterial blood lactate readings (artLAC) and calibrated subcutaneous lactate readings (satLAC) are indicated on -axis and
-axis, respectively. Upper and lower thick lines represent limits for
acceptable lactate trend identification from subcutaneous adipose tissue measurements.
Vertical-hatched lines indicate thresholds for decreasing and increasing
reference lactate concentrations.
