Key result
Inspiratory muscle training linked to ~2.6-point reduction in mMRC dyspnea score in pulmonary edema.
Why the study?
Patients with CKD frequently develop cardiogenic pulmonary edema with respiratory muscle weakness and impaired respiratory function, and the effectiveness of inspiratory muscle training in this population was examined.
Does inspiratory muscle training improve dyspnea, oxygenation, and chest expansion in patients with chronic kidney disease and cardiogenic pulmonary edema?
Does inspiratory muscle training improve dyspnea, oxygenation, and chest expansion in patients with chronic kidney disease and cardiogenic pulmonary edema?

A two-week supervised inspiratory muscle training program significantly improved dyspnea, oxygen saturation, and chest expansion in patients with CKD and cardiogenic pulmonary edema.
Hypothesis-generating for inspiratory muscle training in CKD with cardiogenic pulmonary edema; prospective randomized trials needed before clinical adoption.
Background: Patients with chronic kidney disease (CKD) frequently develop cardiogenic pulmonary edema and associated respiratory muscle weakness, reduced chest expansion, increased dyspnea and reduced quality of life. Inspiratory muscle training (IMT) may help improve respiratory mechanics, oxygenation and patient reported outcomes in this population. Context and Purpose of Study: To examine the effectiveness of supervised IMT in CKD patients with cardiogenic pulmonary edema using chest expansion, mMRC dyspnea, and SpO₂. Results: The study showed significant improvements in all measured outcomes following the intervention. The average mMRC dyspnea score was reduced from 3.60 ± 0.55 to 1.00 ± 0.00 (p < 0.001), while mean SpO₂ increased from 91.80 ± 1.30% to 98.00 ± 1.00% (p = 0.001). Chest expansion also improved in all participants, indicating enhanced respiratory function. Overall, these findings demonstrate meaningful enhancements in respiratory function and clinical status. Conclusion: The study found that IMT helped reduce dyspnea and improve oxygenation and chest expansion in CKD patients with cardiogenic pulmonary edema.

Nair et al. (2026) studied Chronic Kidney Disease (CKD) with Cardiogenic Pulmonary Edema (n=5). Inspiratory Muscle Training (IMT) vs. Pre-intervention baseline was evaluated on mMRC dyspnea score (MD 2.60, p=<0.001). A two-week inspiratory muscle training program significantly reduced the average mMRC dyspnea score by 2.60 points (p < 0.001) and improved oxygen saturation in patients with CKD and cardiogenic pulmonary edema.
