摘　　要：目的探讨有创血压监测值与无创血压监测值之间的线性关系，为临床血压监测提供参考。方法选取ICU监测无创血压与有创血压的患者32例，采取自身对照的方法，同时监测患者有创血压及无创血压值，采集数据资料进行比较，并进行线性关系分析。结果采集有效数据98对，所得数据有创血压收缩压及舒张压值分别为（146．93±21．426），（71．32±13．152）mmHg，均高于无创血压值的（124．02±19．417），（68．86±15．251）mmHg，差异均有统计学意义（t分别为15．301，3．363；P〈0．05）；有创血压与无创血压存在线性关系（r=0．880，P〈0．05）。结论有创血压与无创血压所得监测值之间有差异，不可相互替代，可使用无创血压监测值推导计算有创血压监测值。Objective To investigate the linear relationship between invasive blood pressure and noninvasive blood pressure, providing references for clinical blood pressure monitoring. Methods Totals of 32 ICU patients were chosen, and their invasive blood pressure and non-invasive blood pressure were monitored at the same time by self-reflection methods. The data were collected and compared, and linear correlation was analyzed. Results Totals of 98 pairs of valid date were collected. The invasive systolic and diastolic blood pressure were respectively （146. 93 ±21. 426） and （71.32 ± 13. 152） mm Hg, higher than the non-invasive systolic and diastolic blood pressure which were （ 124. 02 ± 19. 417） and （68.86 ±15. 251 ） mm Hg, and the differences were statistically significant （ t = 15.301,3. 363, respectively; P 〈 0.05 ）. And there was a linear relation between invasive blood pressure and non-invasive blood pressure （ r = 0. 880, P 〈 0. 05 ）. Conclusions There is statistically significant difference between invasive blood pressure and non-invasive blood pressure, which are not substitutable for each other. And non-invasive blood pressure monitoring values can be used to deduce and calculate theinvasive blood pressure monitoring values.
