本研究旨在調查侵入性動脈血壓（直接法）和自動非侵入性間接血壓（間接法）測量所得的血壓值之間的相關性。研究樣本取自於南部某醫學中心加護病房已放置侵入性動脈導管，而且手臂能測量非侵入性間接血壓值的患者，共收案144位病患，每位病患最多測30量次，最少測量1次，共測得1186人次血壓值。本研究六位測量員先進行前趨研究測試，取得測量員間一致性達97%。資料分析以Excel建檔，再以EPI-INFO軟體（6.01版）進行描述性分析，並運用SAS統計軟體之GEE進行重複測量分析，比較直接法與間接法的相關性及相關性之強弱。研究結果顯示：侵入性動脈血壓和自動非侵入性間接血壓測量所得的血壓值具有顯著相關；即非侵入性間接收縮壓、舒張壓、平均血壓分別爲歸零前侵入性動脈收縮壓、舒張壓、平均血壓之62%+31.6、78.3%+.72、70.6%+8.8。非侵入性間接收縮壓、舒張壓、平均血壓分別爲歸零後侵入性動脈收縮壓、舒張壓、平均血壓之62%+31.2、86%-2.9、73.37%+6.3。故建議對於已放置侵入性動脈導管的病患，即可直接採用侵入性動脈血壓測量值來監測及處置病人的病情變化，不需同時測量兩種血壓值。

The purpose of this study was to investigate the relevance between the invasive arterial pressure measurement value and noninvasive blood pressure measurement value. A total of 1,186 blood pressure values from 144 patients were obtained. The statistical procedures applied in data management (by Excel) were descriptive statistics from EPI-INFO (6.01 edition). Repeat measurement analysis used Generalized Estimating Equations (GEE). The result indicated that there was significant relevance between these two kinds of blood pressure measuring methods. It indicated that the systolic, diastolic and mean blood pressure value of noninvasive blood pressure were equal to the systolic, diastolic and mean blood pressure value of invasive arterial pressure's 62 percent+31.6; 78.3 percent+0.72; 70.6 percent+8.8 before the monitor of invasive arterial pressure returned to zero. We therefore suggest that patients who already set the invasive arterial pressure line do not need to measure two kinds of blood pressure at the same time.
