Clinicians sometimes gather the evidence of hypovolemic and septic shocks by looking at patient’s central ve**us oxygen saturation (ScvO2) from blood samples taken from the*central internal jugular vein. This procedure is invasive for patients and cumbersome for clinicians. **w researchers at the*University of Electronic Science and Tech**logy of China are reporting on a new **n-invasive optical probe that can measure continuous tissue blood oxygen saturation (StO2) jst over the jugular vein area.
The device consists of two near-infrared detectors and LED illumination that produces light at three different wavelengths. It*is placed on the skin just above an*internal jugular vein with the help of ultrasound guidance.
The researchers tested the tech**logy on real patients with shock, comparing the readings taken with the near infrared probe against the standard of care ScvO2, demonstrating considerable correlation between the two and pointing to **n-invasive blood monitoring for shock as being the way to do it in the future.
