To compare accuracy of blood pressure measurements using a live subject and a simulator arm, and to determine students' preferences regarding measurement.
This was a crossover study comparing blood pressure measurements from a live subject and a simulator arm. Students completed an anonymous survey instrument defining opinions on ease of measurement.
Fifty-seven students completed blood pressure measurements on live subjects while 72 students completed blood pressure measurements using the simulator arm. There were no significant systematic differences between the 2 measurement techniques. Systolic blood pressure measurements from a live subject arm were less likely to be within 4 mm Hg compared with measurements of a simulator arm. Diastolic blood pressure measurements were not significantly different between the 2 techniques.
Accuracy of student measurement of blood pressure using a simulator arm was similar to the accuracy with a live subject. There was no difference in students' preferences regarding measurement techniques.
比较使用真人手臂和模拟手臂测量血压的准确性，并确定学生对测量方法的偏好。
这是一项交叉研究，比较了真人手臂和模拟手臂测量血压的结果。学生们完成了一份匿名调查工具，对测量的易用性表达了自己的看法。
57 名学生对真人手臂进行了血压测量，72 名学生使用模拟器手臂进行了血压测量。这两种测量技术之间没有显著的系统差异。与模拟手臂相比，来自真人手臂的收缩压测量值更有可能低于 4mmHg。两种技术的舒张压测量值无显著差异。
学生使用模拟器手臂测量血压的准确性与使用真人手臂相似。学生对测量技术的偏好没有差异。
