摘要：Apparatus for measuring the variability of cardiovascular parameters, having aphotoplethysmographic (PPG) probe, including a modulated first light source and aphotodetector, a demodulator connected to the photodetector for demodulating PPGsignals detected by the photodetector, an analog to digital converter for digitizing thedemodulated signals, and a processor for repeatedly analysing the PPG signals for apredetermined number of times. A method for measuring the variability of cardovascularparameters.
