Kashiwagi Y, et al. - Researchers determined the predictors of oxygenation impairment in patients with type B acute aortic dissection (AAD). Blood samples taken from patients with type B AAD who had been medically treated and underwent computed tomography were analyzed for markers of inflammation, such as the C-reactive protein (CRP) levels and white blood cell count. The severity of respiratory failure was determined via assessing the arterial partial pressure of oxygen/fraction of inspired oxygen ratio (PaO₂/FiO₂). They found a correlation of oxygenation impairment with younger age and a higher peak CRP level in this patient populace.
