SYSTEMS AND METHODS FOR DETERMINING RESPIRATION INFORMATION USING FREQUENCY DEMODULATION |
摘要 |
A patient monitoring system may receive a physiological signal such as a photoplethysmograph (PPG) signal. The PPG signal may include a pulsatile component that functions as a carrier signal and a frequency modulation component that represents respiration information. The patient monitoring system may more the frequency modulation component to a baseline component of the PPG signal. Respiration information may be calculated based on the frequency modulation component. |
