Device that allows patient brain monitoring by a noninvasive method, permanently measuring oxygen in brain blood.


Oximetry is a common method for analyzing saturation in O2 and frac components of the blood. Non-invasive cerebral oximetry uses infrared spectroscopy (NIRS) for O2 saturation in a small region of cerebral cortical vasculature.

Cerebral / somatic oximetry INVOS has the following features: continuous monitoring, immediate alarm, easy use technique, improvement of postoperative results through continuous intraoperative monitoring it provides, is the only oximeter that delivers cerebral and somatic regional oximetry simultaneously, is noninvasive, , provides immediate feedback and can consistently indicate regional oxygen saturation (rSO2) values in the brain and other regions of the body at the same time.

The INVOS system technology is based on infrared light spectroscopy. The infrared light passes through the skin, the skull and dura mater, reaching the gray matter of the cortex. Then the NIRS light scatters and a portion of the light is reflected by the erythrocytes passing through the capillary circulation and is measured at 30-40 mm by the LEDs. Most commonly, the measurement area of cerebral oximetry is the cerebral cortex.
