o实战培训implementation, a plethysmographic signal is filtered relative to a Mayer Wave frequency to provide an output related to low frequency blood volume variability. In another implementation, the photoplethysmographic signal is first procesd to obtain a heart rate signal and the heart rate signal is in turn procesd to obtain information regarding low frequency heart rate variability. In either ca, a Mayer Wave effect having potential diagnostic significance can be monitored using a photoplethysmographic instrument such as a pul oximeter.
