Overview of pulmonary vasculitis and diffuse alveolar hemorrhage
Pulmonary vasculitis can present in the ICU in various ways, including diffuse alveolar hemorrhage. Common manifestations include coughing up blood or respiratory failure. Renal failure is another reason for ICU admission, and some patients may have both pulmonary and renal involvement. The most common type of pulmonary vasculitis is ANC-associated vasculitis, with granulomatosis with polyangiitis and microscopic polyangiitis being the primary subtypes. The key is to recognize the similar manifestations of these diseases and treat them accordingly.
