Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults with chronic spinal cord injury who exhibit signs of sleep-disordered breathing.
✕Probably not a fit
Patients who are on continuous mechanical ventilation or have severe heart failure may not benefit from this study.

What this trial studies
This study investigates the effects of daily hypercapnia treatments on respiratory recovery in veterans with chronic spinal cord injuries. The researchers hypothesize that these treatments will improve respiratory symptoms and alleviate sleep apnea, which are common complications following spinal cord injuries. The pilot study will involve administering hypercapnia treatments over two weeks to assess their impact on respiratory function. The approach is based on previous findings that suggest respiratory muscle training can enhance recovery in patients with spinal cord injuries.
Why it matters
Potential benefit: If successful, this treatment could significantly improve respiratory function and quality of life for patients with spinal cord injuries.
How similar studies have gone: While the approach of using hypercapnia for respiratory recovery is novel, previous studies have shown promise in related areas of respiratory muscle training.
