Central blood pressure waveform estimation device and peripheral blood pressure waveform detection device

摘要

A central blood pressure waveform estimation device has a pulse wave detection section, a transfer function storage section, and a central blood pressure waveform calculation section. The pulse wave detection section non-invasively detects a peripheral pulse wave. The transfer function storage section stores a transfer function calculated in advance based on a peripheral pulse waveform detected by the pulse wave detection section and a central blood pressure waveform invasively measured. The central blood pressure waveform calculation section calculates a central blood pressure waveform based on a peripheral pulse waveform newly detected by the pulse wave detection section and the transfer function stored in the transfer function storage section.
