A simulator for oscillometric blood-pressure signals to test automated noninvasive sphygmomanometers
Abstract:
A device was developed allowing to generate simulated human blood pressure signals for the purpose of testing the performance of automated noninvasive sphygmomanometers. The apparatus reproducibly generates blood-pressure oscillations synthesized from prerecorded measurements on human subjects. These real-life data allow for a much better evaluation of the accuracy of blood-pressure measurements than the existing simulators using artificial and thus less realistic waveforms. To assess the performance of a given sphygmomanometer under both stable and varying conditions, generated signals can be repeated in their original shape or distorted by well-defined artifacts. In comparison to clinical tests, the procedural influences on the performance testing of sphygmomanometers are largely reduced when the simulator is used.

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...
