Could brief Low-Oxygen breathing help hearts after spinal cord injury?
NCT ID NCT06691165
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether short, controlled sessions of breathing lower oxygen (called low oxygen therapy) can help stabilize 24-hour blood pressure in people with chronic cervical spinal cord injury. Ten participants will undergo 4 days of treatment, with blood pressure and heart function measured before and after. The goal is to see if this simple approach can reduce cardiovascular risk in this population.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- low oxygen therapy (intermittent hypoxia)
- What this could lead to
- If it works, this could point toward a non-drug way to improve blood pressure stability and reduce heart disease risk in people with spinal cord injury.
- What could go wrong
- This is a very small early-phase trial with only 10 participants, so results may not apply widely. The therapy involves controlled low-oxygen breathing, which may not be safe for everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Are between the ages of 19-65 * Living with a chronic cervical (at or above T1) spinal cord injury of at least one year * Are fluent in english Exclusion Criteria: * High-cervical injuries requiring ventilator assistance to breathe will be excluded on account of the necessity of the facemask for the delivery of hypoxia * Unhealed fracture, contracture, or pressure sore that might interfere with participants' ability to complete the protocol * Additional concurrent neurological conditions (e.g., multiple sclerosis, Parkinson disease, stroke or brain injury) * Uncontrolled cardiovascular or pulmonary disease * Severe neuropathic pain * Severe recurrent autonomic dysreflexia * History of seizure disorders * Known pregnancy
