How to Calculate Classic Shunt
Classic Shunt Equation: Qs/Qt = ((CcO2 – CaO2) / (CcO2 – CvO2)) * 100
Indicator or efficiency of pulmonary system:
- < 10% = normal lungs
- 10-20% = minimal effect
- 20-30% = significant pulmonary disease
- > 30% = life-threatening
| CcO2: Capillary oxygen content in Vol% (mL O2/dL blood): | |
| CaO2: Arterial oxygen content in Vol% (mL O2/dL blood): | |
| CvO2: Mixed venous oxygen content in Vol% (mL O2/dL blood). | |
| Shunt % |
Qs/Qt normal less than 10%
