Apparatus and method for electrocardiogram-assisted blood pressure measurement

摘要: Apparatus, method, and software for electrocardiogram-assisted non-invasive arterial blood pressure d stiffness measurement is disclosed including brachial cuff with flexible electrodes, control box rigid associated hardware/software. Cuff wrapped around upper arm while electrodes on device are touched fingers of other hand. Device acquires simultaneous ECG/oscillometric data during deflation. Processing unit determines ECG R-peak positions to isolate pulses calculate pulse transit time. Change in amplitude as function used constructing oscillometric envelope calculating using empirical coefficients. time independently envelopes finding with/without Fusion algorithm combines results robust vessel evaluation. sends physiological information personal computer/smartphone wirelessly, further analysis. Computer/smartphone transmits third party patient management.
