[Methods for increasing the reliability and noise protection of arterial pressure measurement channel]
Abstract:
Noninvasive measurement of arterial blood pressure is an important function of modem monitoring systems. Presently, most arterial pressure measurement channels implement oscillometric method. This method is based on detection of small-amplitude pulsation of limb volume below occlusion cuff during compression/decompression. The main goal of the upgrade to the oscillometric method is to increase the accuracy, reliability, and noise protection of detection of arterial pressure parameters. This work describes a possible approach to improvement of reliability of the oscillographic method based on synchronous detection of several signals (e.g., volume signal, tachosignal and its derivatives with simultaneous correction of signal processing data on the bases of a priori information about signal, and processing adaptation of data processing algorithm to given signal realization).

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.
