Positioning The Inspectra Sto Sensor; Data Display - Hutchinson Technology InSpectra StO2 Tissue Oxygenation Monitor 650 Gebrauchsanleitung

Positioning the InSpectra
cautIoN:
• S evere bends and kinks in the sensor cable or optical cable
can distort the InSpectra
bend radius tighter than 25mm or 1 inch is not acceptable.
See figure 18.1.
• E xcessive patient motion can cause transient
InSpectra StO Measurements.

• I naccurate measurements can result from:
– Contaminating the window on the adhesive side of the InSpectra StO
– Placing the InSpectra StO
– Indocyanine green and methylene blue dyes present in the blood (they absorb in the same wavelength
region as used by the InSpectra StO
– Methemoglobin, carboxy-hemoglobin and other dyshemoglobins present in the blood.
