A research team led by investigators at Mayo Clinic in Florida has found that a small device worn on a patient's brow can be useful in monitoring stroke patients in the hospital. The device measures blood oxygen, similar to a pulse oximeter, which is clipped onto a finger.

The tool, known as frontal near-infrared spectroscopy (NIRS), could offer hospital physicians a safe and cost-effective way to monitor patients who are being treated for a stroke, in real time. The device sticks like an adhesive bandage onto each of the patient's eyebrows and works like the pulse oximeter that is usually used on a patient's finger to monitor health or brain perfusion during surgery.

If the device is successfully tested in upcoming studies and miniaturized, the NIRS might also be useful in military settings to assess and monitor blood functioning due to brain injuries.
