Objective:
To compare readings obtained using two automated blood pressure (BP) recording devices, BpTRU and Omron 907, in a clinical setting.
Methods:
Two series of 50 patients attending a hypertension unit for 24-h ambulatory BP monitoring had BP recorded either every 1 or every 2 min using BpTRU and Omron 907 devices with the order of the measurements being randomized.
Results:
No significant differences for systolic BP between the mean readings taken using the BpTRU or Omron 907 recorders at either 1 or 2 min were observed. Diastolic BP readings were similar using the 1-min interval setting but were 5.0 mmHg lower for the Omron 907 (P<0.001) when readings were taken at 2-min intervals.
Conclusion:
BP measurements can be made in the clinical setting using either the BpTRU or Omron 907 automated sphygmomanometers.

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.
