  • Title: [Diagnostic importance of the alveolar-arterial oxygen gradient].
    Author: Weinans MA, Drost-de Klerck AM, ter Maaten JC.
    Journal: Ned Tijdschr Geneeskd; 2012; 156(21):A4482. PubMed ID: 22617069.
    Abstract:
    BACKGROUND: The alveolar-arterial (A-a) oxygen gradient is the difference between the partial pressure of oxygen in the alveoli and the partial pressure of arterial oxygen and can be elevated in the case of pulmonary disease. CASE DESCRIPTION: We describe a 41-year-old patient with pneumonia who presented with abdominal pain, in whom calculation of the A-a gradient could have led to earlier diagnosis. CONCLUSION: The A-a oxygen gradient is mainly of diagnostic importance and the presented nomogram allows easy and quick interpretation. This might lead to a more frequent use of the A-a oxygen gradient in the future.
