| Abstract: | 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. |
