The present invention relates to a method for estimating central aortic blood pressures. An oscillometric waveform is derived from a pressure cuff. An aortic-to-brachial (A2B) pressure waveforms generalized transfer function is established. An aortic pressure waveform is reconstructed by the generalized transfer function according to the oscillometric waveform. Therefore, aortic blood pressures are obtained by the aortic pressure waveform. The present invention also relates to an apparatus capable of estimating central aortic blood pressures by using the foregoing method.本發明係有關於一種中央動脈血壓估計方法。該方法包含:擷取壓脈帶內一壓力振盪波形;建立一中央動脈對上臂動脈血壓波形之廣義轉換函數;根據該壓力振盪波形並使用該廣義轉換函數產生一中央動脈壓力波形;以及根據該中央動脈壓力波形得到中央動脈之壓力值。本發明亦有關於一種使用上述方法以估計中央動脈血壓之裝置。S21,S22,S23,S24‧‧‧步驟
