There are few suitable methods for monitoring blood pressure continuously (or intermittently) for research in adult stroke patients, who are ill but do not justify invasive intensive care monitoring.
We tested a neonatal arm blood pressure in adults by placing it on the forefinger ("finger cuff"). We compared the repeatability of the finger cuff with blood pressure measured by a standard adult arm cuff using the oscillometric technique in 168 ambulatory outpatients attending a cerebrovascular disease clinic.
The mean difference between sequential mean blood pressure readings with the finger cuff was 0.55 mm Hg (95% confidence interval (CI) -14.36 to 15.47 mm Hg), and for the arm cuff was 3.31 mm Hg (95% CI -23.33 to 16.71 mm Hg). Measurements made with the arm cuff were shown to affect subsequent arm cuff readings made within a few minutes of the first. The mean difference between the finger cuff and arm cuff mean blood pressure readings was 0.03 mm Hg (95% CI -26.07 to 26.14 mm Hg) and agreement was better when the blood pressure was measured with the finger cuff first rather than the arm cuff. However, although there was no difference in the mean blood pressure recordings both systolic and diastolic blood pressure measurements differed systematically between arm and finger cuff.
The reproducibility of sequential blood pressure measurements made with the finger cuff was better than with the arm cuff. The performance of the finger cuff compared with that of the arm cuff was sufficiently good to encourage use of the finger cuff in research involving automatic intermittent monitoring to observe sequential blood pressures over time in stroke patients. However, measurements of systolic and diastolic pressure were not the same with the two cuffs and further work on calibration of the finger cuff would be useful.
对于成年中风患者的研究而言，几乎没有适用于连续（或间歇）监测血压的方法，这些患者虽患病，但无需进行侵入性重症监护监测。
我们通过将新生儿手臂血压测量设备置于食指上（“指套”）来测试其在成人中的适用性。我们在一家脑血管疾病门诊的168名门诊患者中，使用示波技术比较了指套与标准成人手臂袖带测量血压的重复性。
使用指套连续测量的平均血压读数之间的平均差异为0.55毫米汞柱（95%置信区间（CI）-14.36至15.47毫米汞柱），而使用手臂袖带的平均差异为3.31毫米汞柱（95%CI -23.33至16.71毫米汞柱）。结果显示，使用手臂袖带进行的测量会影响随后几分钟内进行的首次手臂袖带读数。指套与手臂袖带平均血压读数之间的平均差异为0.03毫米汞柱（95%CI -26.07至26.14毫米汞柱），且先使用指套测量血压时一致性更好。然而，尽管平均血压记录没有差异，但手臂袖带和指套之间的收缩压和舒张压测量存在系统性差异。
使用指套连续测量血压的可重复性优于手臂袖带。与手臂袖带相比，指套的性能足够好，足以鼓励在涉及自动间歇监测以观察中风患者随时间变化的连续血压的研究中使用指套。然而，两种袖带测量的收缩压和舒张压并不相同，进一步校准指套的工作将很有帮助。
