Effect of Hypercapnia Treatment on Respiratory Recovery After Spinal Cord Injury
VA Office of Research and Development
Summary
It is estimated that 1,275,000 people in the United States alone live with spinal cord injury, including around 100,000 Veterans with spinal cord injury, making the V.A. the largest integrated health care system in the world for spinal cord injuries injury care. New therapies are needed to prevent the morbidities and mortalities associated with the high prevalence of respiratory disorders in Veterans with spinal cord injury. The current research project and future studies would set the base for developing innovative therapies for this disorder. This proposal addresses a new therapeutic intervention for sleep apnea in spinal cord injury. The investigators hypothesized that daily hypercapnia treatments improve respiratory symptoms and alleviate sleep apnea in patients with chronic spinal cord injury. The investigators will perform a pilot study to examine the impact of daily hypercapnia treatments for-two week durations among Veterans with spinal cord injury. The investigators believe that this novel approach to treating sleep apnea and will yield significant new knowledge that improves the health and quality of life of these patients.
Description
One of the most devastating consequences of cervical spinal cord injury (SCI) is damage to the phrenic motor network, controlling the diaphragm (primary muscle of breathing). Subsequent diaphragm paralysis or paresis results in life-threatening impairments in breathing and can necessitate a need for ventilator assistance. Respiratory and cardiovascular complications are the most common causes of death in the first year post-injury (51% combined). Thus, there is an urgent need to develop strategies for improving function for people with acute and chronic spinal cord injury. Currently, treatment…
