根據美國統計,每年住進加護病房人數約400萬人,死亡率為百分之八至百分之二十左右,隨著醫療科技日新月異的進步,重症照護的設備也更加多元,有效的血液動力學監測,可預期病情發展,並提早控制病情。
然而單純的平均收縮壓與舒張壓不能直接對應任何病症,必須透過動態血壓波形計算出相關生理參數,推測受試者生理狀態。PiCCO則為最新型之血液動力學監測系統,與傳統非侵入式量測儀器不同在於,其屬微侵入式血壓量測系統,能透過注入食鹽水的水溫變化,對應波形面積計算出更多心臟相關參數。
本實驗取出PiCCO量測40隻豬隻施打藥物後各項生理參數的變化如收縮壓、舒張壓、平均血壓,並搭配篩選出有效可利用的血壓波形,利用量測到的全身血管阻力數值,與高解析度之連續血壓波波形變化相對應,將單一血壓波形進行數學式擬合,找出全身血管阻力與血壓波下降斜率的關係。最後透過量化分析中的相關分析與迴歸分析統計血壓下降指數與全身血管阻力的關係,並利用血管電路模型確立血壓下降與其他生理參數之間能利用數學式進行轉換對應。
According to the statistics in the U.S, about four million people stayed in the intensive care unit (ICU) andand the mortality rate is 8-20%, the intensity of the care provided in ICUs requires many monitoring devices. .With the advance of science and medical technology, critical care equipment become more diverse and precise.
Effective hemodynamic monitoring can expect the develop of disease and control the disease early.
However,the simple average systolic pressure and diastolic pressure cannot directly correspond to any disease.To predict the physiological status of the subject,it must calculate physiological parameters by analysising dynamic blood pressure waveform.PiCCO is the newest hemodynamic monitoring system for integrating a wide array of both static and dynamic haemodynamic data through a combination of trans-cardiopulmonary thermodilution and pulse contour analysis.
This study measured physiological parameters of 40 pigs administered variety of drugs,comparing parameters with feature points of BP waveform to screen effective and available BP waveform .Curve fitting for BP waveform to Generate fitting parameters,and use this parameters to find the relationship between falling slope of BP with Systemic Vascular Resistance (SVR).Finally,find the relationship between falling slope of BP with patients ' progress by using quantitative analysis
Including correlation analysis and regression analysis statistics.
