Association Between Fluid Status and Small Airway Dysfunction in Hemodialysis Patients: A Prospective Paired Study

Key Points

• This research aims to explore how fluid status affects small airway function in hemodialysis patients.
• Prospective study design with paired assessments during dialysis.
• Utilized Impulse Oscillometry System (IOS) to evaluate airway function post-dialysis.
• Assessed the relationship between fluid overload and airway function improvement.
• IOS detected significant improvements in small airway function post-dialysis linked to reduced extracellular water.
• Spirometry did not show similar post-dialysis improvements as IOS.
• Findings indicate the potential of IOS in fluid optimization monitoring for hemodialysis patients.
