“…The hybrid sphygmomanometer has the potential to become a replacement for mercury, because it combines some of the best features of both mercury and electronic devices at any rate until the latter become accurate enough to be used without individual validation. 41 …”

Abstract-Accurate measurement of blood pressure is essential to classify individuals, to ascertain blood pressure-related risk, and to guide management. The auscultatory technique with a trained observer and mercury sphygmomanometer continues to be the method of choice for measurement in the office, using the first and fifth phases of the Korotkoff sounds, including in pregnant women. The use of mercury is declining, and alternatives are needed. Aneroid devices are suitable, but they require frequent calibration. Hybrid devices that use electronic transducers instead of mercury have promise. The oscillometric method can be used for office measurement, but only devices independently validated according to standard protocols should be used, and individual calibration is recommended. They have the advantage of being able to take multiple measurements. Proper training of observers, positioning of the patient, and selection of cuff size are all essential. It is increasingly recognized that office measurements correlate poorly with blood pressure measured in other settings, and that they can be supplemented by self-measured readings taken with validated devices at home. There is increasing evidence that home readings predict cardiovascular events and are particularly useful for monitoring the effects of treatment. Twenty-four-hour ambulatory monitoring gives a better prediction of risk than office measurements and is useful for diagnosing white-coat hypertension. There is increasing evidence that a failure of blood pressure to fall during the night may be associated with increased risk. In obese patients and children, the use of an appropriate cuff size is of paramount importance.

“…Auscultatory systolic and diastolic pressures (SBP and DBP) were measured from the left arm with a clinically validated electronic non-mercury sphygmomanometer, Accoson Greenlight 300 (AC Cossor & Son (Surgical) Ltd, Harlow, UK) 15 and a stethoscope. The cuff pressure was automatically deflated from B200 to 10 mm Hg at a rate of 2-3 mm Hg s À1 .…”

It is accepted that accuracy of auscultatory blood pressure (BP) measurement is influenced by measurement conditions. However, there is little comparative quantitative clinical data. The aim of this study was to provide these data. Auscultatory systolic and diastolic BPs (SBPs and DBPs) were measured in 111 healthy subjects under five different conditions (resting, deeper breathing, talking, head and arm movement). The measurement sequence was randomized, and repeated three times. BPs and their within-subject variabilities were compared with resting values. SBP and DBP changed significantly in comparison with the resting condition: decreasing by 4.4 and 4.8 mm Hg, respectively, with deeper breathing (both Po0.001), increasing by 3.7 and 5.0 mm Hg with opposite arm movement, and increasing by 5.3 and 6.2 mm Hg with talking (all Po0.001). The mean differences between deeper breathing and talking were 9.7 and 11.0 mm Hg for SBP and DBP. The within-subject variability for repeat measurement of SBP and DBP under resting condition were 3.7 and 3.2 mm Hg and increased for non-resting conditions (all Po0.05, except for DBP while talking). We have shown that measurement conditions significantly influence manual auscultatory BPs and their measurement variabilities, and we provide quantitative data to allow comparison of the effects.

“…6 This decision is justified by the results of two recent validation studies of electronic auscultatory devices 14 that used the ESH-IP, but with simultaneous measurements and reported similar findings as in validation studies of the same devices using the ESH-IP with sequential measurements. 15,16 The accuracy of at least four mercury-free electronic auscultatory devices has been tested using the ESH-IP protocol, using sequential [15][16][17][18] or simultaneous measurements. 14 The Accoson Greenlight device (Accoson Works, Harlow Business Park, Harlow, Essex, UK), which has a LED scale display similar to an aneroid device, was shown to have 84 of the systolic and 74 of the diastolic BP measurements (out of 99) within 5 mm Hg from those obtained by a mercury sphygmomanometer using sequential measurements, 15 and 81 and 87, respectively, using simultaneous measurements.…”

This study validated a hybrid mercury-free device as a replacement of the mercury sphygmomanometer for professional use, and also as a standard for future validations. A validation study was performed according to the European Society of Hypertension International Protocol 2010 (ESH-IP) in 33 subjects using simultaneous blood pressure (BP) measurements. A total of six BP measurements were taken per participant simultaneously by a supervisor (S; hybrid auscultatory device Nissei DM3000) and two observers (A and B; mercury sphygmomanometers). ESH-IP analysis (99 BP readings): mean device-observer systolic/diastolic BP difference 0.2±2.0/0.1±2.0 mm Hg; systolic BP differences p5/10/15 mm Hg in 97/99/99 readings, respectively (diastolic 98/99/99). All 33 subjects had 2 of 3 BP differences p5 mm Hg and none without a difference p5 mm Hg. Further analysis (198 BP readings): mean differences S-A 0.1 ± 2.4/0.2 ± 2.4 mm Hg (systolic/diastolic), S-B 0.3 ± 2.1/0.2 ± 2.2, A-B 0.2 ± 2.4/0.0 ± 2.3; differences p2 mm Hg S-A in 88/84% (systolic/diastolic), S-B 87/85%, A-B 87/86% and p4 mm Hg S-A 95/ 96%, S-B 95/96%, A-B 95/98%. In conclusion, a hybrid mercury-free auscultatory BP monitor comfortably passed the ESH-IP 2010 requirements and has the same level of accuracy as the mercury sphygmomanometer. This device appears to be a reliable alternative to the mercury sphygmomanometer for professional use and also as a standard for future validations.
