The FORE-SIGHT® Oximeter, Model MC-2000 Series is indicated for the continuous noninvasive monitoring of regional hemoglobin oxygen saturation of blood in the brain and skeletal muscle. It is intended for use in any individual at risk for reduced-flow or no-flow ischemic states.
When used with Large sensors, the FORE-SIGHT Oximeter is indicated for use on the brain of adults and children over 40 kg. When used with Medium sensors, the FORE-SIGHT Oximeter is indicated for use on the brain of small adults and children between 4 and 80 kg. When used with Small sensors, the FORE-SIGHT Oximeter is indicated for use on the brain of infants and neonates ≤ 8 kg.
When used with Medium sensors, the FORE-SIGHT Oximeter is indicated for use on skeletal muscle of infants, children and adolescents between 5 and 50 kg.
The prospective clinical value of data from the FORE-SIGHT Oximeter has not been demonstrated in disease states and these data should not be used as a sole basis for diagnosis or therapy.
Indications for use as stated in the FDA summary.
