The ultimate goal is to improve disease management to achieve optimal quality of life and exercise capacity in this group of patients. <strong>Materials and Methods: </strong>Through a cross-sectional design, the current study enrolled 46 dialysis patients by simple sampling between Jan 2019 and Jan 2020. Some CPET parameters such as AT, VO<sub>2</sub>, VO<sub>2</sub>/kg, SPO<sub>2</sub>, minute ventilation CO<sub>2</sub> production/O<sub>2</sub> consumption ratios (VE/VCO<sub>2</sub> and VE/VO<sub>2</sub>, respectively), O<sub>2</sub> pulse, heart rate reserve (HRR), breathing reserve (BR) and end-tidal carbon dioxide pressure (PETCO<sub>2</sub>) were focused. <strong>Results: </strong>Although a limited sample size, the current study showed that VO<sub>2</sub>/Kg, VE/VCO<sub>2</sub>, PETCO<sub>2</sub>, and SPO<sub>2</sub> are the main parameters affected by dialysis as expected. <strong>Conclusion: </strong>The current study suggests using cardiopulmonary rehabilitation for all chronic medical conditions such as chronic kidney disease and end-stage renal disease that increase the rate of metabolic acidosis.
