This application provides a clinical method, system, device, and medium for detecting bowel and bladder movements. First, raw pulse rate time-series data of the patient is collected. The raw pulse rate time-series data undergoes quality verification and signal cleaning to obtain effective pulse rate time-series data. Based on the effective pulse rate time-series data, the mean pulse rate within the current detection window is calculated, and a pre-determined individualized resting pulse rate baseline value is obtained. The difference between the mean pulse rate within the current detection window and the individualized resting pulse rate baseline value is determined as the dynamic pulse rate offset. The dynamic pulse rate offset is judged using predefined bowel and bladder behavior detection rules, and the event confidence level for the current time period is output. The event confidence level is compared with a preset clinical decision threshold. If the event confidence level exceeds the clinical decision threshold, a graded early warning signal is generated and pushed to the clinical nursing system. The above scheme can achieve non-invasive detection of clinical bowel and bladder events.

A method for deriving a measure of PPG variability which is indicative of fluid responsiveness. The PPG signal is processed with an adaptive re-sampling algorithm which re-samples the signal with a sampling density which is a function of instantaneous pulse rate. When the PPG signal is subsequently transformed with a discrete frequency-domain transform such as an FFT, the resulting frequency spectrum reflects a variability of the sample in which the FM contribution is largely eliminated. This provides variability information which is more reflective of the AM contribution which is the dominant contribution associated with respiration.
