30.2 rSO2 Safety Information
CAUTION
• rSO
2
monitoring is intended for use in individuals greater than 2.5 kg at risk for reduced-flow or no-
flow ischemic states.
• Do not use the rSO
2
value as the sole basis for making decisions regarding diagnosis or therapy
because the rSO
2
values represent a small volume of tissue beneath the sensor and may not reflect
oxygenation disturbances that occur elsewhere.
• Use only recommended or provided accessories. Use any other sensor will compromise accuracy.
• Use of an electrosurgical instrument in the vicinity of the monitor may interfere with the signal and
result in inaccurate rSO
2
measurement.
NOTE
• Environments with excessive ambient light such as bright sunlight or strong operating room
lighting may require loosely covering the area of the sensor with an opaque drape.
