Do the QardioArm and Omron M6 Comfort blood pressure devices meet the accuracy requirements of the ESH-IP Revision 2010 compared to mercury standard readings?
The QardioArm and Omron M6 Comfort blood pressure devices are accurate and suitable for self-measurement in the general population and type II diabetic patients, respectively.
Background: Following the European Society of Hypertension International Protocol (ESH-IP) Revision 2010, QardioArm ® and Omron M6 Comfort IT ® oscillometric devices were evaluated in the general population and in patients with type II diabetes, respectively, for self-blood pressure (BP) measurement. Methods: Both devices, QardioArm ® and Omron M6 Comfort ® , measure BP at the brachial level. The ESH-IP Revision 2010 includes a total number of 33 subjects. For each measure, the difference between observer and device BP values was calculated. In all, 99 pairs of BP differences are classified into three categories (≤5, ≤10, and ≤15 mmHg). The protocol procedures were followed precisely. Results: QardioArm® and Omron M6 Comfort ® fulfilled the requirements of the ESH-IP and passed the validation process successfully. For QardioArm ® , a total of 69 out of 99 comparisons for systolic blood pressure (SBP) showed an absolute difference within 5 mmHg and 82 out of 99 for diastolic blood pressure (DBP). As for Omron M6 Comfort ® , a total of 83 out of 99 comparisons for SBP showed an absolute difference within 5 mmHg and 77 out of 99 for DBP. The mean differences between the device and mercury readings were 0.7±5.9 mmHg for SBP and 0.3±4.1 mmHg for DBP for QardioArm ® and −1.4±4.7 mmHg for SBP and −2.1±4.3 mmHg for DBP for Omron M6 Comfort ® . With regard to part 2 of ESH-IP 2010, 27 out of 33 subjects had a minimum of two out of three measurements within 5 mmHg difference for SBP and 31 out of 33 subjects for DBP for the QardioArm ® , and 29 out of 33 patients had a minimum of two out of three measurements within 5 mmHg difference for SBP and 26 out of 33 patients for DBP for Omron M6 Comfort ® . Conclusion: QardioArm ® and Omron M6 Comfort ® readings differing from the mercury standard by <5, 10, and 15 mmHg fulfill the ESH-IP Revision 2010 requirements. Consequently, these two devices are suitable for use in the general population and non-insulin-dependent type II diabetic patients, respectively.

Chahine et al. (Fri,) conducted a observational in General population and type II diabetes (n=33). QardioArm and Omron M6 Comfort oscillometric devices vs. Mercury standard was evaluated on Difference between observer and device BP values. QardioArm and Omron M6 Comfort devices fulfilled ESH-IP validation requirements, with mean differences from mercury readings of 0.7±5.9/0.3±4.1 mmHg and -1.4±4.7/-2.1±4.3 mmHg, respectively.
