Objective:
The evaluation of automated office blood pressure (AOBP) measurement compared to 24-hour ambulatory BP monitoring (ABPM), Home BP measurement and manual BP.
Patients And Methodology:
A total of 123 hypertensive patients were included. Overall, 68 completed the 4 measurement: Manual BP in the office (Omron 705 CP 3 measurements), ABPM (Spacelab of 96 measurement/per 24hours), Home BP (18 measurement during 3 days), AOBP using the SPRINT methodology: lying patient, isolated with an automatic measurement (Dinamap) every minutes during 8minutes (average of the last 3 measurement). Twenty-two out of 123 patients (26%) did not complete the Home BP measurement.
Results:
The average of AOBP measurement using SPRINT is 132±12/69±9mmHg, of ABPM 134±13/79±9, of Home BP: 135±13/70±13 and of manual BP: 138±13/72±11mmHg The Bland & Altman method highlight that the AOBP, the ABPM and home BP measurement are 3 substitutable methods. The confidence interval is smaller between the ABPM and the AOBP than with the home BP.
Conclusion:
The automated office blood pressure, as the Home BP measurement, can be considered a reliable substitute for the ABPM, when the later is not accessible, and when a repeated therapeutic evaluation is needed, or when the home BP measurement is not done. These results encourage us to use it more frequently as the Canadian Hypertension Education Program recommend it.

01:30Equipments 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.

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...
