Abstract
Devices and methods for monitoring intracranial hemodynamic parameters, such as intracranial pressure, cerebral blood volume, cerebral blood flow, and cerebral perfusion pressure are disclosed. In one aspect, the devices and methods may involve receiving at least one impedance plethysmography signal. Waveforms may be extracted from the impedance plethysmography signals and used for estimating the intracranial hemodynamic parameters. Various characteristics may be determined from the waveforms to aid in the estimation of intracranial hemodynamic parameters.
