Researchers want to see if heart rate variability—the natural changes in how fast your heart beats—can help doctors figure out the best amount of high-flow nasal cannula support you need. High-flow nasal cannula is a breathing tube that delivers extra oxygen and air pressure to help your lungs. The study will gradually decrease your oxygen flow while monitoring your heart rhythm and lung function to see if heart rate changes warn doctors before you start having trouble breathing.
Right now, doctors don't have a good way to know when patients are ready for less breathing support—some people don't get enough help and their lungs struggle, while others stay on the machine longer than needed, which costs more and can slow recovery. This research explores whether watching your heart rate patterns could give doctors an earlier warning sign that it's time to adjust your treatment.

You will stay connected to heart rhythm and lung monitoring equipment while doctors slowly reduce the flow rate of your breathing support in stages, from high flow down to lower flow. Throughout this process, your oxygen levels will be adjusted to keep you safe, and doctors will continuously track your heart rate patterns and how your lungs are responding. The entire study procedure takes place during your ICU stay and doesn't require extra hospital visits.
