NG replaces OG. Low flow with smaller cannulae.

When I visited Jac tonight, his OG (oral gastric) feeding line had been replaced by a NG (nasal gastric) line, the nasal cannulae from Denver was replaced by a smaller one; and the high-flow was discontinued, replaced by low-flow from the hospital wall oxygen outlet. He is now at 0.02 liter/minute of oxygen via the cannulae.

Earlier in the day, before the switchover, Jac apparently had some A's & B's. Since the switch, he's been doing fine -- he only had one quick desat, and it went away before the nurse got to him.

At home on Sunday night, I turned on my CPAP machine on "slow start" so that there would be less noise for Taj as we went to sleep. When I do that, it's a little more difficult for me to breathe. It dawned on me that the same phenomena was happening to Jac as he was getting weaned off the oxygen at Denver.

I think Jac was having problems with his low-flow because the cannulae was too big and effectively coupled his nose directly to the air supply; and, as they dialed down his airflow to wean him, he was not getting enough total air volume, and couldn't inhale enough through his nose. We never got a chance to discuss this suspicion with the attending at TCH before Jac moved out.

So, maybe, Jac was ready to breathe completely on his own, and we just missed it. We'll know more in the next few days!

With the OG tube out of his mouth, Jac seemed much happier. His mouth has a cute baby-mouth look, and he was occasionally letting his tongue poke out of his mouth, much to his father's delight! On top of that, he kept making motions to suck his thumb -- he would have succeeded, too, if he would just figure out that his thumb should not be held in his fist!
