PURPOSE
To determine whether the HoMedics Model BPA-300 meets American Association for the Advancement of Medical Instrumentation (AAMI) accuracy standards.
METHOD
Simultaneous auscultatory measurements by two observers using a mercury manometer were obtained in participants during measurement with the HoMedics Model BPA-300. Triple measurements were obtained after a minimum of 5 min of rest and 1 min between readings.
RESULTS
In total, 132 participants had 396 nurse-measured blood pressures (BP) and 385 successful systolic and 383 diastolic monitor readings. The initial auscultation systolic BP was less than 100 mmHg in 17 participants (12.9%), between 100 and 160 mmHg in 108 participants (81.8%), and greater than 160 mmHg in seven (5.3%) of participants. The average difference between the observers and device was 0.6+/-4.3 mmHg for systolic and 0.5+/-4.3 mmHg for diastolic-measured BPs by AAMI method 1, which met this guideline. The average difference between observers and device by AAMI method 2 was 0.9+/-4.0 mmHg for systolic and 0.5+/-3.9 mmHg for diastolic-measured BP, which met this guideline.
CONCLUSION
The HoMedics Model BPA-300 meets AAMI accuracy standards using methods 1 and 2.
目的
确定HoMedics BPA - 300型号是否符合美国医学仪器促进协会（AAMI）的准确性标准。
方法
在使用HoMedics BPA - 300型号进行测量时，由两名观察者同时使用水银血压计对参与者进行听诊测量。在至少休息5分钟且每次读数间隔1分钟后进行三次测量。
结果
总共132名参与者进行了396次护士测量的血压（BP），以及385次成功的收缩压和383次舒张压监测读数。17名参与者（12.9%）的初始听诊收缩压低于100 mmHg，108名参与者（81.8%）的收缩压在100至160 mmHg之间，7名参与者（5.3%）的收缩压高于160 mmHg。根据AAMI方法1，观察者与设备之间收缩压测量的平均差异为0.6±4.3 mmHg，舒张压测量的平均差异为0.5±4.3 mmHg，符合该指南。根据AAMI方法2，观察者与设备之间收缩压测量的平均差异为0.9±4.0 mmHg，舒张压测量的平均差异为0.5±3.9 mmHg，符合该指南。
结论
HoMedics BPA - 300型号使用方法1和方法2符合AAMI准确性标准。
