HIFAE: Home High Flow Oxygen to Reduce Acute Exacerbation of COPD
Study Details
Study Description
Brief Summary
The objective of the study is to evaluate the efficacy of home High Flow Oxygen for the reduction of severe exacerbation following admission for a severe exacerbation of COPD or death against standard oxygen therapy.

|---|---|
| Experimental: High Flow Oxygen Therapy

Other: High Flow Oxygen Therapy
HFOT will be delivered validated medical devices and established as follow:
Patient will be acclimatized to HFOT which will aim to achieve a flow of air of 30L/min at a temperature of 34°C using dedicated nasal canula.
Once patient acclimatized, oxygen will be entrained in the HFOT device at a flow that will aim to achieve a saturation > 90%. An arterial blood gas will be performed with such oxygen delivery, flowrate and temperature to ensure a PaO2 ≥ 8kPa

| Other: Long-Term Oxygen Therapy Control arm |
Other: Long-term oxygen therapy
LTOT delivery will be performed according to French guidelines
