Background: The intermittent hemodialysis (IHD) has been a useful renal replacement therapy for critically ill patients.Pulmonary dysfunction in end-stage kidney disease has been seen as a straight effect of circulating uremic toxins or a secondary effect of volume overload, anemia, immune suppression, premature airway closure, ventilationperfusion mismatching, severe mechanical loading, gas transfer defects, malnutrition, electrolyte disorders, and/or acid/base imbalances. Aim of the study: To study effect of Hemodialysis on pulmonary function in patients with end stage renal disease.
