Abstract:
This study proposes additional steps to evaluate and interpret oscillometric blood pressure monitors. 4-quadrant and Bland-Altman plots were created using mean arterial pressures (MAP) obtained every 2 min from 40 dogs from a previous study. New plots were created using values grouped every 10-min intervals instead of individual measurement. Using intervals improved the range of change in MAP assessed in 4-quadrant plots and the concordance between monitors and reduced the limits of agreement in Bland-Altman plots. Interpreting oscillometric MAP values over intervals rather than individual values may be a useful addition to traditional method-comparison studies and to clinical monitoring.

Prepare for the Procedure:
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.

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...
