Overview
There is no established system for the classification of hepatopulmonary syndrome.
Classification
There is no established system for the classification of hepatopulmonary syndrome (HPS).[1]
HPS can be classified in term of severity based on atrial blood gas analysis, as follows:
- Mild: Alveolar-arterial oxygen gradient above, or equal to<math>\geq</math> 15mmHg, partial pressure of oxygen <math>\geq</math> 80mmHg.
- Moderate: Alveolar-arterial oxygen gradient <math>\geq</math>15mmHg, partial pressure of oxygen <math>\geq</math> 60 up to 80mmHg.
- Severe: Alveolar-arterial oxygen gradient <math>\geq</math> 15mmHg, partial pressure of oxygen <math>\geq</math> 50 up to 60mmHg.
- Very severe: Alveolar-arterial oxygen gradient <math>\geq</math>15mmHg, partial pressure of oxygen below 50 mmHg (< 300mmHg while the patient is breathing 100% oxygen).[2]
