Intracranial pressure estimation method and intracranial pressure estimation apparatus

摘要

The intracranial pressure estimation method includes an acquisition step (S10) of acquiring time series data of a subject's ear canal pressure pulse wave, and analyzing the ear canal pressure pulse wave data obtained by digitizing the time series data of the ear canal pressure pulse wave. An analysis step (S12) for calculating the first formant frequency of the pulse wave data, a correction step (S13) for calculating the correction value by correcting the calculated first formant frequency based on the personal information of the subject, and the calculated correction value And an estimation step (S14) for calculating an estimated value of the intracranial pressure based on the above.
