The purpose of this study was to validate the use of a motion tolerant blood pressure monitor (CardioDyne NBP 2000, Luxtec, Worcester, MA) ) against standard manual auscultation at rest and during exercise.
Nineteen subjects (men, N = 9; women, N = 10) participated in the study (mean: age 21+/-1.2 yr; height 172.5+/-8 cm; mass 69.4+/-14.5 kg). Standard Bruce protocol treadmill exercise tests with 12-lead ECG and metabolic measures were administered to the subjects, with blood pressure measures taken at rest before, during, and after the exercise tests. Blood pressure by manual auscultatory sphygmomanometry and the CardioDyne NBP 2000 was recorded simultaneously in the same arm. Manual auscultatory blood pressure measures obtained by one experimenter were used as the criterion measure, and the data of two NBP 2000 audio reviewers were averaged for each data point recorded.
Systolic blood pressure (SBP) and diastolic blood pressure (DBP) via manual auscultation and the NBP 2000 "automatic" values were not significantly different and were highly correlated at rest and during exercise. Resting intraclass correlation SBP values were high (range 0.95 to 0.98), as were DBP intraclass correlation values (range 0.83 to 0.95). Exercise intraclass correlation SBP values ranged from 0.94 to 0.99, and DBP intraclass correlation values from 0.88 to 0.93.
We conclude that the NBP 2000 is simple to use at rest and during exercise stress testing and provides accurate and verifiable information.
本研究的目的是验证一种运动耐受型血压监测仪（CardioDyne NBP 2000，Luxtec，伍斯特，马萨诸塞州）在静息和运动期间相对于标准手动听诊法的使用情况。
19名受试者（男性，N = 9；女性，N = 10）参与了该研究（平均年龄：21±1.2岁；身高172.5±8厘米；体重69.4±14.5千克）。对受试者进行标准布鲁斯方案跑步机运动试验，同时进行12导联心电图和代谢指标测量，并在运动试验前、期间和之后的静息状态下测量血压。在同一手臂同时记录手动听诊血压计和CardioDyne NBP 2000测量的血压。由一名实验者获得的手动听诊血压测量值用作标准测量值，对两名NBP 2000音频审阅者的数据在每个记录的数据点进行平均。
通过手动听诊和NBP 2000“自动”测量得到的收缩压（SBP）和舒张压（DBP）在静息和运动期间无显著差异，且高度相关。静息时组内相关SBP值较高（范围为0.95至0.98），DBP组内相关值也较高（范围为0.83至0.95）。运动时组内相关SBP值范围为0.94至0.99，DBP组内相关值范围为0.88至0.93。
我们得出结论，NBP 2000在静息和运动应激测试中使用简便，可提供准确且可验证的信息。
