To determine the accuracy of the SpaceLabs 90207 ambulatory blood pressure monitor in pregnant women.
Prospective observational study.
Queen Charlotte's and Chelsea Hospital for Women.
One hundred and twenty-two pregnant women from the antenatal population of Queen Charlotte's Hospital.
Evaluation was carried out according to the British Hypertension Society (BHS) Protocol.
The mean difference between observer and device for systolic blood pressure was 3 (SD 4) mmHg. For diastolic blood pressure the difference was 5 (SD 6) mmHg for Phase IV (muffling of Korotkoff sound), and 4 (SD 4) mmHg for Phase V (disappearance of Korotkoff sound). According to the BHS grading criteria, the device reached a B grading for systolic blood pressure. B grading was also reached for diastolic blood pressure (Phase V) but grade C for diastolic blood pressure (Phase IV). The accuracy criteria stipulated by the Association for the Advancement of Medical Instrumentation (AAMI) were also met for both systolic and diastolic blood pressure.
The SpaceLabs 90207, when compared with trained observers, is accurate in determining both systolic and diastolic blood pressure for clinical purposes, as judged by the BHS Protocol in pregnancy.
确定太空实验室90207动态血压监测仪在孕妇中的准确性。
前瞻性观察性研究。
夏洛特女王与切尔西妇女医院。
来自夏洛特女王医院产前人群的122名孕妇。
根据英国高血压学会（BHS）方案进行评估。
观察者与仪器测量的收缩压平均差值为3（标准差4）mmHg。舒张压方面，在第四期（柯氏音减弱）差值为5（标准差6）mmHg，在第五期（柯氏音消失）差值为4（标准差4）mmHg。根据BHS分级标准，该仪器收缩压达到B级。舒张压（第五期）也达到B级，但舒张压（第四期）为C级。收缩压和舒张压均符合美国医疗仪器促进协会（AAMI）规定的准确性标准。
根据孕期BHS方案判断，与经过培训的观察者相比，太空实验室90207在临床应用中测定收缩压和舒张压时具有准确性。
