System for continuous estimation and display of cardiac ejection fraction and end diastolic volume
Abstract
The invention is on a display (for example and heat) to the dilute model the parameter to redirect teat dip on the heart to the seedling to count (EF) to the central to prevent estimation. A are arranged at the central major is made with is arranged on the atrium/ventricle for example heater and display refillers and located at the central lower parts for example thermistor and display concentration detecting elements which a channel model. The basin model is a normal transmission function of lag, a of the output parameters of blood face display quantities of attenuation τ. The measuring are prepared heart rate. A EF=1-EXP (-60/(τ *HR))The continuous computation shoot the menstruation to count (EF). The basin algorithm based on lag normal transmission function of zero-frequency gain, the model can also estimate for cardiac value of measuring pump (CO). Diastole end of the period coil (EDV) and CO, HR and EF function, a continuous computation the obtain. The display concentration detecting element of the reaction for display is slow, advanced determined detecting element (function Hs, wherein the parameter preservation of the storage device, a transmission function data for measuring steps of the bedstead, triangular is Hs first, to enhance the EF measuring accuracy.
