Abstract

A computer-based automated data acquisition and analysis system to help determine cardiac output using a one-step CO2 rebreathing technique is presented. The technique generates all the data required to solve the Fick equation for CO2 by continuously monitoring expired CO2 concentrations at the mouth during a 20-25 s rebreathing maneuver. Through use of digital signal processing techniques, the data points required are automatically determined. Computer-generated cardiac output determinations agreed well with those of an experienced laboratory technician.
