Design and Validation of an Arterial Pulse Wave Analysis Device

[摘要] Arterial pulse wave analysis studies the wave shape of the blood pressure pulse.The pulse wave provides more information than the extreme systolic and dia-stolic pressures, measured with a cuff sphygmomanometer. The aim of theresearch is to investigate the design issues in a pulse wave analysis system,and to compare these to a commercially available system. The system wascompared and validated by measuring the pulse wave at the radial artery(wrist) using the non-invasive technique of arterial tonometry. The designconformed to the IEC-601 safety standard to ensure patient safety. The datawas compared against the data from the commercial system and analysis wasperformed in the time and frequency domain. The performance of the designsuggests that, in some respects, the design was comparable to the commer-cial system, however, a number of performance characteristics fell short of thecommercial system. Suggestions have been made to address these problems infurther research.
