We evaluated the automated system Blood Pressure Measuring System (BPMS) developed by NASA on 277 adult males who elected to have a treadmill test as part of their annual physical. The BPMS uses acoustic transduction with a computer-assisted ECG gating to detect nonsynchronous noise. The BPMS readings were compared to pressures simultaneously measured by trained technicians. For all stages of work, BPMS readings were higher for systolic and lower for diastolic than technician readings. At peak stages of work, BPMS systolic pressures were about 20 mmHg higher than technician readings. Within each 3-min workstage, BPMS readings were found to be more inconsistent than technician readings. The standard errors of measurement for BPMS were from two to three times higher than technician values. These data showed automated blood pressure readings were significantly different than technician values and subject to more random fluctuations. These findings demonstrate the need to view exercise blood pressure measured by automated systems with caution.
我们对美国国家航空航天局（NASA）研发的自动血压测量系统（BPMS）进行了评估，该系统应用于277名选择进行跑步机测试作为年度体检一部分的成年男性。BPMS利用声学传导和计算机辅助心电图门控来检测非同步噪声。将BPMS的读数与经过培训的技术人员同时测量的血压值进行比较。在所有工作阶段，BPMS测得的收缩压读数高于技术人员的测量值，舒张压读数低于技术人员的测量值。在工作的峰值阶段，BPMS的收缩压读数比技术人员的测量值高出约20毫米汞柱。在每个3分钟的工作阶段内，发现BPMS的读数比技术人员的读数更不稳定。BPMS测量的标准误差比技术人员测量值高出两到三倍。这些数据表明，自动测量的血压读数与技术人员测量的值有显著差异，并且更容易受到随机波动的影响。这些发现表明，对于自动系统测量的运动血压需要谨慎看待。
