Ornim Medical, out of Lod, Israel, just received FDA approval for its non-invasive cerebral oxygen monitor for use during surgeries. Back in January, we’ve profiled OrNim’s Targeted Oximetry as a potential diagnostic modality not just for the brain, but for monitoring oxygenation of other organs, such as viscera or extremities.
From Globes Online:
OrNim’s Ultrasound Tagged Light technology – UTLight, transmits a beam of light through tissue to measure the absorption of light by oxygenated and deoxygenated hemoglobin. The system tags the light with ultrasound beams enabling to bypass superficial tissue, and measure absolute oxygen saturation levels within the monitored tissue.
Shechter explains, “If the blood in the area marked by the ultrasound is red and oxygen-rich, it absorbs more tagged light. If the area is light and oxygen-poor, more tagged light is reflected back to us. In this way, we can precisely measure oxygen levels.”
