Blood Circulation of the Forearm Obstructed by Arm Cuff

Caption

Stroke, one of the leading causes of death worldwide, is normally caused by poor blood flow to the brain, or cerebral ischemia. This condition must be diagnosed within the first few hours of the stroke for treatment to be effective. Researchers have developed a device that uses near-infrared light to monitor blood flow. The hybrid instrument, which relies on the combination of two light measurement techniques, could be used to quickly and noninvasively diagnose cerebral ischemia. In the experiment, the blood circulation of the forearm was obstructed by the arm cuff for three minutes.
