HOW DOES THE FORE-SIGHT™ CEREBRAL OXIMETER WORK?
The FORE-SIGHT™ Cerebral Oximeter is a non-invasive device that incorporates CAS Medical System’s exclusive LASER-SIGHT™ technology to project harmless near infrared light through the scalp and skull and into the brain via a disposable sensor on the patient’s forehead. The FORE-SIGHT™ Cerebral Oximeter operates based on the principle that blood contains hemoglobin in two primary forms, oxygenated hemoglobin (HbO2) and de-oxygenated hemoglobin (Hb). These two forms of hemoglobin absorb light in different, measurable ways. Cerebral tissue oxygen saturation (SctO2) levels are found by determining the ratio of oxygenated hemoglobin to total hemoglobin at the microvascular level (arterioles, venules and capillaries) in the region of the brain that is interrogated. The FORE-SIGHT™ Cerebral Oximeter continuously monitors cerebral tissue oxygen saturation SctO2 which is a mixed oxygen saturation parameter and reflects a proportional mix of arterial (~30%) and venous (~70%) blood in the outlyin
