Abstract:
The aim of this study was to evaluate the accuracy of the JAMR upper-arm blood pressure monitor B23 in the general population according to the AAMI/ESH/ISO Universal Standard (ISO 81060-2 : 2018/AMD 1 : 2020). The study recruited participants who met the criteria of the AAMI/ESH/ISO Universal Standard in terms of their number, sex, age, limb size, and blood pressure (BP) distribution. The study involved measuring BP, including both SBP and DBP, using both the test device and a standard mercury sphygmomanometer in sequential measurements. Of 90 participants, 85 qualified participants were analyzed. A total of 255 sets of comparison data (three sets for each subject) were obtained and analyzed. For the validation criterion 1, the mean ± SD of the differences between the JAMR B23 and mercury sphygmomanometer BP readings was -0.24 ± 6.52/-2.67 ± 5.6 mmHg (SBP/DBP). For criterion 2, the SD of the averaged BP (SBP/DBP) differences between the JAMR B23 and reference BP (SBP/DBP) per participant was 5.61/5.13 mmHg (the requirement was ≤6.95/6.43 mmHg by calculation). The JAMR B23 passed all the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2 : 2018/AMD 1 : 2020) and can be recommended for clinical and self/home use in the general population.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
