Cerebral oximetry is a medical technology used to monitor the oxygen levels in the brain.
A non-invasive procedure that uses light to measure the saturation of oxygen in the blood vessels of the brain.
Provides real-time information about the oxygenation status of the brain, which can be useful in monitoring patients during surgery, in intensive care units, or in emergency situations.
Cerebral oximetry is typically done using a device a near-infrared spectroscopy (NIRS) monitor.
The NIRS monitor uses a special light sensor that is placed on the patient’s forehead.
The device then sends a beam of light into the brain tissue, and the light that is reflected back is analyzed to determine the oxygen levels.
It measures the amount of oxygenated and deoxygenated hemoglobin in the blood vessels of the brain.
The results are displayed on a screen, typically as a percentage, with normal cerebral oxygen saturation levels are typically between 60% and 80%.
Any reading below 50% is considered to be critical.
