SwRI Biomedical Engineering: Cardiovascular Research

 
 

SwRI engineers developed mathematical models of the conduction pathways in the heart and software that correlates the models with intracardiac electrograms and electrocardiograms. The software will allow physicians to quickly identify the location(s) of abnormal conduction pathways.

Several studies have been completed and numerous products have been developed at Southwest Research Institute (SwRI) to further advance cardiovascular health.


Sensors have been developed at SwRI to measure the following:

  • Noninvasive blood pressure (NIBP)

  • Phonocardiogram (PCG)

  • Pulsewave velocity (PWV)

  • Hemodynamic flow

  • Blood gases

  • Electrical conduction pathways

  • Cardiac output

Noninvasive Blood Pressure Monitoring

SwRI is a recognized leader in the development of new blood pressure monitoring systems. In the 1970s, we were the first to develop an automatic blood pressure monitor by transferring technology used to noninvasively measure baboon blood pressure.

 

Our engineers developed other monitors, including:

  • One of the first ambulatory blood pressure monitors

  • Stress test blood pressure monitor

  • Continuous noninvasive blood pressure monitor

Continuing Cardiovascular Research

Today, SwRI is developing new techniques for monitoring, analyzing, and modeling blood pressure waveforms. Our innovative engineers have made significant contributions to the field of tonometry including automatic localization of the artery, novel multisensor arrays, and waveform calibration.

 

Using mathematical models of the cardiovascular system to correct radial blood pressure signals, SwRI has developed unique methods to produce accurate, continuous estimates of central aortic blood pressure. Our recent work in the area of pulsewave velocity has resulted in significant intellectual property for our clients.
