Oxygen utilization coefficient
WebApr 6, 2024 · RQ stands for respiratory quotient and it is the ratio of the volume of carbon dioxide released to the volume of oxygen used in cellular respiration. It is estimated per unit time per unit weight at standard temperature and pressure. The respiratory quotient of protein is known to be 0.9. 2. WebJan 1, 1988 · The ventilation-perfusion index (VQI), an estimate of venous admixture, and the oxygen extraction index (O 2 EI), an estimate of tissue oxygen utilization coefficient, previously described, were calculated on-line from arterial and mixed venous oxyhemoglobin saturations using a computer. Effective monitoring was accomplished 85% of the total time.
