Oxygen Consumption (VO₂): Measured using a metabolic cart, the patient's oxygen consumption was determined to be 250 mL/min. Arterial Blood Gas Analysis: Blood samples were taken to assess arterial oxygen content. The results showed: <br>- Hemoglobin (Hb): 15 g/dL<br>- Arterial Oxygen Saturation (SaO₂): 92%<br>- Arterial Oxygen Content (CaO₂) was calculated using the formula:<br>\[<br> CaO_2 = (Hb \times 1.34 \times SaO_2) + (0.003 \times PaO_2)<br> \]<br>Assuming a PaO₂ of 60 mmHg, CaO₂ was calculated to be approximately 19.1 mL O₂/dL bloo<br><br>Therefore, while the Fick Formula provides a useful framework, it is often necessary to incorporate additional factors for a complete understanding of diffusion in complex systems.
