Method and system for monitoring intracranial pressure
First Claim
1. A method for monitoring intracranial pressure, comprising:
- emitting an electromagnetic wavelength into forehead tissue of a patient;
detecting characteristics of the electromagnetic wavelength after the electromagnetic wavelength has been scattered by the tissue, wherein the characteristics include variations in the electromagnetic wavelength corresponding to a pulse;
analyzing the variations to identify venous pulsations; and
determining whether intracranial pressure is elevated in the patient based on a correlation between the venous pulsations and levels of intracranial pressure.
