Pulmonary gas exchange during hemodialysis and peritoneal dialysis: interaction between respiration and metabolism.

This review concerns the alterations in pulmonary gas exchange during hemodialysis and peritoneal dialysis. The occurrence of hypoxemia during hemodialysis has led to numerous studies that now provide sufficient data to explain this complex phenomenon. The role of substrate metabolism during hemodialysis and peritoneal dialysis are explored as it relates to alterations in ventilation. Comparison to similar types of ventilatory changes occurring during total parenteral nutrition are discussed. The effect of peritoneal dialysis on pulmonary function is also described.
