Abstract 4146800: A Retrospective Analysis of Measured Versus Estimated Resting Oxygen Uptake for Derivation of Fick Cardiac Output in Patients in the Cardiac Intensive Care Unitdoi:10.1161/circ.150.suppl_1.4146800Acute heart failureOxygen uptake
Cardiac output (CO) was determined with a modification of the Fick method using estimated, instead of measured, oxygen consumption values. This avoids several possible sources of error in connection with air sampling and oxygen content analysis, thus a relaxed, steady state is obtained more easily...
