Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This trial is testing a new approach to oxygen therapy for people having a sudden, severe flare-up of COPD (a chronic lung disease). Instead of the standard treatment of 100% oxygen, paramedics will either give you carefully adjusted oxygen levels aimed at keeping your blood oxygen in a specific safe range (88–92%), or standard high-concentration oxygen. The goal is to see if the adjusted approach helps more people survive and recover better.
Doctors have long wondered whether the standard high-concentration oxygen given during COPD flare-ups might actually harm some patients by making their blood too acidic and worsening their breathing. This trial exists to find out whether carefully adjusting oxygen levels could save more lives and prevent serious complications.

When paramedics arrive, you will be randomly assigned to receive either adjusted oxygen or standard high-concentration oxygen while they treat your flare-up. If you're in the adjusted group, paramedics will use a special monitor to measure your blood oxygen and carbon dioxide levels, adjusting oxygen as needed to keep you in the target range. You will be followed for 30 days after treatment to track your recovery, hospital stay, and overall health outcomes.
