HOW ACCURATE IS THE FORE-SIGHT™ CEREBRAL OXIMETER?
FORE-SIGHT™ Cerebral Oximeter readings have been confirmed in both animal and human studies. In a recent human validation study conducted at Duke University looking at 253 samples, the FORE-SIGHT™ Cerebral Oximeter determined absolute cerebral tissue oxygen saturation values (SctO2) showed a strong correlation with the reference SctO2 over a wide range of pulse oxygen saturation values (SpO2). The bias and precision (1 standard deviation) for the FORE-SIGHT™ Cerebral Oximeter SctO2, compared to reference SctO2, (derived from co-oximetry of arterial and jugular bulb blood samples) was 0.07 ± 3.699 (The absolute root mean are accurate to within 3.69 points). The high level of accuracy obtained by the FORE-SIGHT™ Cerebral Oximeter is achieved by compensating for the influence of background light absorbing and scattering elements in the blood and tissue not associated with hemoglobin. This is accomplished by a three-pronged technological approach: interrogation via a laser light source wit
