An analysis of the relationship between respired gases, mixed venous oxygen, and cardiac output

Thesis

The focus of this thesis is the estimation of cardiac output and mixed venous O2 saturation (S_v¯O₂) through the analysis of respired gases. Current methods for measuring these parameters are limited by invasiveness, inaccuracy, or impracticality. Computed cardiopulmonography (CCP) is a novel technique for the assessment of respiratory and cardiac function, where each of these limitations may be addressed. CCP combines a molecular flow sensor (MFS) with a comprehensive ca...
