摘要： Disclosed herein is a new and improved non-invasive bed sensing system for detecting and monitoring physiological movements such as heartbeat and respiration. The system may employ a hydraulic fluid to transduce the physiological pressures to an integrated pressure sensor and a new and improved signal processing method to identify individual cardiac pulses from the electronic signals generated by the hydraulic transducer. The system provides increased sensitivity capable of capturing quantitative pulse and respiration rates with subtle changes, ability to distinguish between instances of low pulse rate and shallow breathing, and improved comfort over existing systems.
