Objective:
The aim of this study was to validate the TM-2441 ambulatory blood pressure monitoring (ABPM) device using the ISO 81060-2:2013 standard.
Participants And Methods:
Participants were healthy individuals aged more than 12 years who were recruited from among the outpatients and volunteers of Jichi Medical University (Tochigi, Japan). The same-arm sequence protocol (clinical validation) and the opposite-limb simultaneous method (ambulatory validation) from the ISO 81060-2:2013 standard were used.
Results:
One hundred and seven participants were enrolled; 85 participated in the clinical validation and 35 participated in the ambulatory validation (13 participants were included in both validation protocols). The TM-2441 device performed well against the standard in both the clinical and ambulatory validations; the mean and SD values for the differences between device and observed systolic and diastolic blood pressure values in both tests fulfilled criterion 1 and criterion 2 of the standard. The Bland-Altman plots did not show any systematic variation in the error.
Conclusion:
The TM-2441 ABPM device was accurate and fulfilled all ISO 81060-2:2013 standard requirements for ABPM determination in adults. It is therefore suitable for use for ABPM in adults with hypertension.

Measurement of Blood Pressure
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...
Special considerations while measuring blood pressure
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.

Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...
