More Information
Summary:The invention provides methods and systems for continuous noninvasive measurement of vital signs such as blood pressure (cNIBP) based on pulse arrival time (PAT). The invention uses a body-worn monitor that recursively determines an estimated PEP for use in correcting PAT measurements by detecting low frequency vibrations created during a cardiac cycle, and a state estimator algorithm to identify signals indicative of aortic valve opening in those measured vibrations. 本发明提供了用于基于脉搏到达时间(PAT)连续无创地测量生命体征(诸如血压(cNIBP))的方法和系统。本发明使用通过检测心动周期期间产生的低频振动递归地确定估计的PEP用于校正PAT测量的身体佩带式监测器且使用状态估计器算法以识别指示所述测量的振动中的主动脉瓣打开的信号。
