Cardiac Output Calculator
Professional Cardiac Output Calculator using Fick principle. Accurately measures blood circulation efficiency with VO₂, CaO₂, and CvO₂ inputs. Essential medical tool.
About Cardiac Output Calculator
This Cardiac Output Calculator implements the Fick principle - the gold standard for measuring how effectively the heart pumps blood throughout the body. Designed for medical professionals and physiology students, it provides precise calculations of cardiac output (CO) and cardiac index (CI), critical parameters in cardiovascular assessment. The calculator uses oxygen consumption and arterial/venous oxygen content differences to determine heart performance.
How to Use
Enter Parameters:
- Oxygen Consumption (VO₂): Typical resting value 250 mL/min
- Arterial O₂ Content (CaO₂): Normal range 18-20 mL/dL
- Venous O₂ Content (CvO₂): Normal range 12-15 mL/dL
Click Calculate:
- Instantly computes Cardiac Output (L/min)
- Automatically calculates Cardiac Index (L/min/m²)
Interpret Results:
- Normal CO: 4-8 L/min at rest
- Normal CI: 2.5-4.0 L/min/m²
- Values outside ranges may indicate cardiac issues
Clinical Significance
This tool helps evaluate:
- Heart failure severity
- Response to cardiac medications
- Pre/post-operative cardiac function
- Exercise physiology measurements
