Figure 2From: Monitoring trauma and intensive care unit resuscitation with tissue hemoglobin oxygen saturationShock resuscitation variables during shock resuscitation (first 24 hours) and the following 12 hours. (a) Tissue hemoglobin oxygen saturation (StO2), deltoid skeletal muscle and subcutaneous StO2 saturation, monitored non-invasively using a prototype near-infrared spectrometer (Biospectrometer-NB Oximeter; Hutchinson Technology, Inc., Hutchinson, MN, USA). Do2 I, systemic oxygen delivery index. (b) Mixed venous hemoglobin oxygen saturation (SvO2) monitored invasively using a pulmonary artery catheter with fiberoptic oximetry capability. BD, base deficit; lactate, serum lactate concentration. Reproduced with permission from [8].Back to article page
