Go with the flow (low-flow that is)

Tyler is doing great! Today at rounds we decided to try moving from hi-flow to low-flow for his respiratory assistance. In recent days he has been really starting to swing his Oxygen saturation. We were concerned that this may be related to the pressure in his head, but on closer inspection we think it was the humidity from his high-flow condensing and flowing up into his nose. I don't know about you but I have a hard time breathing when I get water up my nose.

Most of the time he is doing really well but the swings were starting to become a concern. Low-flow is 100% O2 at a much lower volume. He was getting 1 Liter per minute of 21%(room-air) on high-flow, now he's getting 100% but at a much smaller rate (25 cc/min). Without the humidity he seems to be doing just fine.

I just did the math and Tyler has made so much progress that he has now reduced his oxygen intake more than you or I would going from sea-level to the top of Mt Everest (without supplemental Oxygen). He started at 42%, he is now at 25%
