  1. Any suggestions for patients whose nostrils are too small (i.e. it occludes >50% of nostril)?

  2. Great question! The manufacturer recommends keeping nasal occlusion under 50% to allow excess air to escape around the cannula. I only had two sizes on hand for the video, but more are available—just be sure they’re compatible with your specific high-flow unit, as these aren’t usually interchangeable. If you can’t find a small enough cannula for your patient, it may be safer to opt for another oxygen delivery method, like an oxygen chamber, standard low-flow oxygen, or intubation if needed.

  3. Are you able to trim the nasal cannulas to better fit the patients? We struggle with the cannulas being too long and occluding up against nasal tissue.
