title: A system for analysis of arterial blood pressure waveforms in humans.
abstract: Recent developments in arterial hemodynamics have indicated that the human arterial pressure waveform contains more information than is available from conventional sphygmomanometry. This information includes indices describing left ventricular systolic function and arterial properties. A cheap and reliable system was designed and implemented using readily available hardware for recording, analysis, and storage of arterial pressure waveforms. The system embodies an online technique for synthesizing ascending aortic pressure waveform from recordings made at different peripheral sites of the human arterial system. Eighteen indices are then derived from arterial pressure waveforms. This system can be used in an outpatient clinic for assisting in current pharmacological management of cardiovascular disease. It can also be extended to the critical care area, where the extra information provided aid in assessing the patient's condition.
