New treatment option for Work of Breathing
Official title The Role of Heliox in Respiratory Control
ClinicalTrials.gov ID: NCT07424014
What this study is testing
What is Heliox inspirate?
Heliox inspirate is an investigational medicine, being studied as a potential treatment for work of breathing.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- Warfighters are frequently exposed to environments and life-support systems that increase breathing resistance and the work of breathing (WOB), such as aircraft on-board oxygen generation systems and underwater breathing apparatuses. Elevated WOB increases the perception of breathing difficulty (dyspnea) and has been associated with impaired cognitive performance, including slower reaction time and reduced accuracy during attention-demanding tasks.
- Phase 4: studies an already-approved treatment
