Abstract：
UNASSIGNED: Mercury sphygmomanometer (MS) has now been less and less used and no new devices have been manufactured (according to Minamata convention 2013). The application of the electronic sphygmomanometer (ES) in clinical practice has become increasingly common. However, reliable evidence for the use of the ES in high-altitude areas remains scarce. The purpose of this study was to validate the applicability of the ES in high altitude areas.
UNASSIGNED: In Luhuo County, Sichuan Province, China, 3,400 m above the sea level, two trained physicians measured the blood pressure (BP) of participants using both the mercury sphygmomanometer and the ES. Pearson correlation analysis and paired T-test, respectively, were used to compare the correlation and the difference between the BP values measured by the two devices. The applicability of the ES in high-altitude areas was evaluated according to the validation standards of the 2018 Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Collaboration Statement.
UNASSIGNED: In this study, 257 participants were included. There was a strong correlation between BP values measured by the two devices, with correlation coefficients for systolic blood pressure (SBP) and diastolic blood pressure (DBP) of 0.97 and 0.93, respectively. Compared with the MS, the ES tended to measure the subjects\' DBP (76.21 ± 13.29 mmHg vs. 76.53 ± 14.07 mmHg; P = 0.557) accurately, but overestimate the SBP of the subjects (123.32 ± 22.25 mmHg vs. 121.34 ± 22.88 mmHg; P < 0.001) to some extent. The consistency of the two devices in the classification of normal BP, prehypertension, and hypertension was 88.9%, 80.7%, and 89.2%, respectively.
UNASSIGNED: In general, the utilization of ES at 3,400 m altitude successfully met the validation standards of the AAMI/ESH/ISO Collaboration Statement. The use of ES can be recommended at a high altitude, including up to 3,400 m. In addition, because the ES tended to overestimate SBP, we speculate that it may need to be calibrated in high-altitude areas.

摘要：
■水银血压计（MS）现在已经越来越少地使用，并且没有制造新的设备（根据Minamata公约2013）。电子血压计（ES）在临床实践中的应用已变得越来越普遍。然而,在高海拔地区使用ES的可靠证据仍然很少。本研究的目的是验证ES在高海拔地区的适用性。
■在卢霍县，四川省,中国,海拔3400米,两名训练有素的医师使用水银血压计和ES测量参与者的血压(BP).Pearson相关分析和配对T检验，分别,用于比较由两个设备测量的BP值之间的相关性和差异。根据2018年医疗器械促进协会/欧洲高血压学会/国际标准化组织（AAMI/ESH/ISO）合作声明的验证标准，评估了ES在高海拔地区的适用性。
■在这项研究中，包括257名参与者。这两个设备测得的BP值之间存在很强的相关性，收缩压（SBP）和舒张压（DBP）的相关系数分别为0.97和0.93。与MS相比,ES倾向于测量受试者的DBP(76.21±13.29mmHg与76.53±14.07mmHg；P=0.557）准确，但高估了受试者的SBP（123.32±22.25mmHg与121.34±22.88mmHg；P<0.001）在一定程度上。两种设备在正常BP分类中的一致性，高血压前期,高血压占88.9%,80.7%,和89.2%，分别。
■一般来说，在3,400m高度使用ES成功达到AAMI/ESH/ISO合作声明的验证标准。建议在高海拔地区使用ES,包括高达3,400米。此外，因为ES倾向于高估SBP，我们推测它可能需要在高海拔地区进行校准。
