Abstract:
This article introduces a measuring method for invasive blood pressure based on SecWave technology and a testing method of effectiveness based on IBP database and simulator. Besides, quantified indexes are set out for the accuracy evaluation, such as static pressure accuracy, accuracy of dynamic pressure pulse wave recognition, pulse rate and the response time, so as to provide an important reference method of effectively objective evaluation for invasive blood pressure measurements.

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.
