The noninvasive FORE-SIGHT ELITE Module Tissue Oximeter is intended for use as an adjunct monitor of absolute regional hemoglobin oxygen saturation of blood under the sensors in individuals at risk for reduced flow or no-flow ischemic states. The FORE-SIGHT ELITE Module Tissue Oximeter is intended to allow for the display of StO2 on a third party display/patient monitor. The FORE-SIGHT ELITE Module Tissue Oximeter when used with large sensors, is indicated for use on adults and transitional adolescents ≥40 kg. When used with Medium Sensors, the FORE-SIGHT ELITE Module Tissue Oximeter is indicated for use on pediatric subjects ≥3 kg. When used with Small Sensors, the FORE-SIGHT ELITE Module Tissue Oximeter is indicated for cerebral use on pediatric subjects <8 kg and non-cerebral use on pediatric subjects <5kg.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
