Hepatopulmonary syndrome classification
Introduction
Overview
Overview
There is no established system for the classification of hepatopulmonary syndrome. Nevertheless, HPS can be classified in term of severity based on arterial blood gas analysis.
Classification
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]
