Cardiopulmonary Exercise Test Parameters among Dialysis Patients with End-Stage Renal Disease.

Abstract

Background: The current study aimed to assess some parameters of the cardiopulmonary exercise test (CPET) among end-stage renal disease patients who underwent dialysis. The ultimate goal is to improve disease management to achieve optimal quality of life and exercise capacity in this group of patients.

Materials and methods: 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, VO₂, VO₂/kg, SPO₂, minute ventilation CO₂ production/O₂ consumption ratios (VE/VCO₂ and VE/VO₂, respectively), O₂ pulse, heart rate reserve (HRR), breathing reserve (BR) and end-tidal carbon dioxide pressure (PETCO₂) were focused.

Results: Although a limited sample size, the current study showed that VO₂/Kg, VE/VCO₂, PETCO₂, and SPO₂ are the main parameters affected by dialysis as expected.

Conclusion: 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.
