End-stage renal disease typically requires haemodialysis to help replace kidney function. However, changes in oxygen uptake during haemodialysis have been linked to increased all-cause mortality. This complication of haemodialysis is linked to decreasing fluid volume, compromising perfusion and leukostasis within pulmonary tissue. However, an alternative cause of reduced oxygen availability (hypoxia) during haemodialysis is acute alkalosis. Alkalosis during haemodialysis can cause hypoxia via dysregulated ventilation and impaired ability for tissue to extract oxygen. Despite strong rationale for these mechanisms, few studies have fully explored causes of hypoxia during haemodialysis. Greater understanding may help to mitigate risk associated with this vital treatment option.
