Answer

Pulmonary complications have been reported in approximately 54% of patients with AKI and are the single most significant risk factor for death in patients with AKI. In addition, diseases exist that commonly present with simultaneous pulmonary and renal involvement, including the following:

  • Goodpasture syndrome
  • Granulomatosis with polyangiitis (Wegener granulomatosis)
  • Polyarteritis nodosa
  • Cryoglobulinemia
  • Sarcoidosis

Hypoxia commonly occurs during hemodialysis and can be particularly significant in the patient with pulmonary disease. This dialysis-related hypoxia is thought to occur secondary to white blood cell (WBC) lung sequestration and alveolar hypoventilation.
