The first microprocessor-based dual thermistor
cardiac output computer was developed at Southwest Research Institute
(SwRI) from concept to manufacturing.

Cardiac Output Computer |
Conventional cardiac output computers measure the injectate temperature
externally, or outside the body, before it is injected into the
catheter. As part of this product, SwRI software engineers developed an
algorithm for a cardiac output computer that determines cardiac output
based on pulmonary artery blood temperature distribution and injectate
temperature, measured within the right atrium using a second temperature
thermistor.
Building on our experience in cardiovascular monitoring, SwRI's computer
scientists developed an inexpensive, noninvasive, patented method for
measuring continuous cardiac output, combining sophisticated signal
processing techniques with commonly available patient data to measure
the heart's pumping ability.
