Validation of three professional devices measuring office blood pressure according to three different methods: the Omron BP10, the Omron HBP T105 and the Pic Indolor Professional.

Objective: Three professional devices for office blood pressure (BP) measurement, using three different algorithms to determine BP, were evaluated according to the International Protocol of the European Society of Hypertension. The Omron BP10 uses the oscillometric method, the Omron HBP T105 (module HBP-M3600) uses the smart inflation mode and high-speed measurement and the Pic Indolor Professional check is a hybrid sphygmomanometer.

Methods: The International Protocol of the European Society of Hypertension is divided into two phases and includes a total number of 33 participants on whom the validation is performed. In each study and for each participant, four BP measurements were performed simultaneously by two observers using mercury sphygmomanometers alternately with three measurements by the tested device. The difference between the observers and the device BP values was calculated for each measure. The 99 pairs BP differences were classified into three categories (
Results: All three tested devices passed the first and the second phase of the validation process. The mean differences between the device and mercury readings were -0.02 +/- 3.7 and -2.2 +/- 3.9 mmHg for SBP and DBP, respectively, for the Omron BP10 device; 1.5 +/- 5.7 and -0.6 +/- 3.8 mmHg for the Omron HBP T105 device; and -0.6 +/- 1.7 and -0.4 +/- 1.5 mmHg for the Pic Indolor Professional device.

Conclusion: Readings of the Omron BP10, the Omron HBP T105 and the Pic Professional check, fulfill the criteria of the International Protocol of the European Society of Hypertension. Therefore, these devices can be used in the clinic.
