摘　　要：利用光电容积脉搏波描记法(PhotoPlethysmoGraphy,PPG)测量人体生理参数具有操作简单、性能稳定和适应性强等优点。采用反射式光电测量法获得桡动脉PPG信号,对PPG信号做快速傅里叶变换,分析频域实现人体心率和呼吸频率的检测。实验结果表明利用快速傅里叶变换获得的心率和呼吸频率与监护仪获得的相应数据之间有良好的相关性。基于快速傅里叶变换的生理参数测量仪可便携、快速、准确的测量心率和呼吸频率,适用于医院或家庭的日常监护。PhotoPlethysmoGraphy（PPG）is used to measure the human physiological parameters because it is simple,stable and strong adaptability.The human heart rate and respiration rate is detected in frequency domain of the PPG signal which is computed by Fourier transform.The PPG signal of the radial artery is obtained based on reflecting photoelectric mode established.The corresponding date of heart and respiration rates obtained by Fast Fourier transform of PPG good agree with the results detected by medical monitor.The method of Fast Fourier transform can realize to measure human heart and respiration rates quickly and accurately.A portable device can be made by this method and can be used in hospital or daily life care.
