  • Validation of the Omron HEM-7201 upper arm blood pressure monitor, for self-measurement in a high altitude environment, according to the European Society of Hypertension International Protocol revision 2010
    2016
    Co-Authors: Kawing Cho, Xingshan Zhao, Maoyi Tian, Ph. D, Yonghao Lan, Lijing L. Yan
    Abstract:

    Few studies have been conducted on blood pressure monitors and their use at high altitude. This study is the first to evaluate an automated blood pressure device at high altitude following a standard validation protocol. The Omron HEM-7201 upper arm automatic blood pressure monitor was tested for accuracy in Lhasa, Tibet, China (3650 m above sea level) according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP2). Thirty-three participants received 9–10 sequential blood pressure measurements alternating from a Mercury Sphygmomanometer and the device. The mean device-observer measurement difference was 1.0 ± 5.9 mmHg for systolic blood pressure (SBP) and −3.1 ± 4.6 mmHg for diastolic blood pressure (DBP). Of the 99 measurement pairs analyzed, 72, 90, and 97 device readings were within 5, 10, and 15 mmHg, respectively, of the observer measurements for SBP, and 68, 92, and 99 readings for DBP. The number of participants with at least two out of three measurements within 5mmHg was 27 for SBP and 25 for DBP. Three participants had no measurements within 5 mmHg for SBP or DBP. The Omron HEM-7201 passes the ESH-IP2 validation criteria and can therefore be recommended for use in adults in this setting

This study is the first to evaluate the accuracy of an automatic blood pressure monitor in a high-altitude environment following a standard validation protocol. The Omron HEM-7201 upper arm blood pressure monitor was tested for accuracy in Lhasa, Tibet, China (3650 m above sea level) according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP2). Thirty-three participants received 9–10 sequential blood pressure measurements alternating between a Mercury Sphygmomanometer and the device. The mean device-observer measurement difference was 1.0±5.9 mm Hg for systolic blood pressure (SBP) and −3.1±4.6 mm Hg for diastolic blood pressure (DBP). Of the 99 measurement pairs analyzed, 72, 90 and 97 device readings were within 5, 10 and 15 mm Hg, respectively, of the observer measurements for SBP, and 68, 92 and 99 readings for DBP. The number of participants with at least two out of three measurements within 5 mm Hg was 27 for SBP and 25 for DBP. Three participants had no measurements within 5 mm Hg for either SBP or DBP. As a result, the Omron HEM-7201 passes the ESH-IP2 validation criteria and can therefore be recommended for use in adults in this setting.

  • comparison of the automated non invasive oscillometric blood pressure monitor bptru with the auscultatory Mercury Sphygmomanometer in a paediatric population
    Blood Pressure Monitoring, 2004
    Co-Authors: Gurdial S Mattu, Alraj S Hera, James M Wrigh
    Abstract:

    Background To directly compare the accuracy of the BpTRU™ (an automated oscillometric blood pressure device) with standard auscultatory Mercury sphygmomanometry in a pediatric population. Design The BpTRU™ was connected in parallel with a standard Mercury Sphygmomanometer. Two observers measured the blood pressures at the same time as it was being measured by the BpTRU™. The observers and the BpTRU™ were all blinded from each other. Methods For each of the demographic data—subject age, sex and arm sizes—the mean, standard deviation (SD) and range was calculated. The difference between the mean BpTRU™ and the standard reference measurements (observer average) was calculated with SD and ranges. The percentage of measurements within 5, 10 and 15 mmHg agreement was expressed. Results From the 36 subjects recruited aged 3–18 years, 162 pairs of sitting blood pressures were included. The difference between the mean BpTRU™ readings and the reference standard measurements (as determined by the observers) was 1.45±5.67 mmHg for systolic blood pressures, and –3.24±7.39 mmHg for diastolic pressure and 0.20±2.47 bpm for heart rate. Conclusion The BpTRU™ is of similar accuracy in measuring blood pressure in children as it was in an adult population.

  • comparison of the oscillometric blood pressure monitor bpm 100 beta with the auscultatory Mercury Sphygmomanometer
    Blood Pressure Monitoring, 2001
    Co-Authors: Gurdial S Mattu, Thomas L Perry, James M Wrigh
    Abstract:

    BACKGROUND: To compare directly the accuracy of the BPM-100(Beta) monitor (an automated oscillometric blood pressure device) with standard auscultatory Mercury sphygmomanometry. DESIGN: The BPM-100(Beta) was connected in parallel via a T-tube to a Mercury Sphygmomanometer. The BPM-100(Beta) and two trained observers (blinded from each other and from the BPM-100(Beta)) measured the sitting blood pressure simultaneously. METHODS: Means, standard deviations and ranges were calculated for all the demographic data: age, arm size, heart rate and blood pressure. The agreement between the BPM-100(Beta) and the mean of two observers (the reference) was determined and expressed as the mean +/- SD, as well as the percentage of differences falling within 5, 10 and 15 mmHg. RESULTS: Of the 92 subjects recruited, 85 (92.4%) met the inclusion criteria, and 391 sets of sitting blood pressure and heart rate measurements were available for analysis. The mean difference between the BPM-100(Beta) monitor and the reference was -0.62 +/- 6.96 mmHg for systolic blood pressure, -1.48 +/- 4.80 mmHg for diastolic blood pressure and 0.14 +/- 1.86 beats/min for heart rate. The only limitation of the device was its tendency to underestimate higher systolic blood pressures. This problem has been addressed by a minor change in the algorithm (see the companion publication, Blood Press Monit, 6, 161-165, 2001). CONCLUSION: The BPM-100(Beta) is an accurate blood pressure monitor for the office setting, meeting all requirements of the Association for the Advancement of Medical Instrumentation and achieving an 'A' grade according to the British Hypertension Society protocol.
