I’ve gotten a lot of questions about Fick CO calculation recently, so let’s go over it: Not my favorite way to get a cardiac output, but if you’re using the Fick method, here’s how to do it right: 1. Choose one calculator. MDCalc works well. 2. Use an ABG for your SaO2. Don’t rely on the pulse ox. 3. Get a true SvO2 from a PA catheter. Central line samples give you ScvO2, which will overestimate. 4. Enter hemoglobin, heart rate, and age to get your numbers. You’ll get cardiac output, cardiac ind

Estimated Fick vs. Thermodilution: Which One Do You Trust? 🤔 When measuring cardiac output (CO), we often rely on either the Estimated Fick method (which uses assumed VO2 and calculated variables) or Thermodilution (which directly measures CO using injectate and temperature changes). Key differences: -Estimated Fick: Can be less accurate in critically ill patients due to reliance on assumed values. -Thermodilution: More reliable but affected by arrhythmias, tricuspid regurg, and injectate techn
