Pulmonary gas exchange during hemodialysis: a comparison of subjects with and without COPD on bicarbonate hemodialysis.

Little is known about the effect of hemodialysis (HD) on gas exchange in subjects with chronic obstructive pulmonary disease (COPD). The purpose of this study was to examine blood gases and pH in COPD patients undergoing HD with bicarbonate dialysate. We studied thirteen subjects with COPD and thirteen controls (CON).
