A new device known as NIRS uses light to non-invasively monitor blood oxygenation in the brains of stroke patients

Approximately one third of stroke patients experience another stroke while they’re still in the hospital. Nurses therefore keep a close eye on them, and arrange for them to be taken for tests if a subsequent stroke is suspected. Unfortunately these tests can be invasive, and in some cases are even potentially harmful to the patient. A new device being developed at the Mayo Clinic in Florida, however, could watch for strokes simply by shining light onto a patient’s forehead.
