Hi again TThomas,
It would be great if a phrenic nerve pacer, or diaphragm pacing system might work for Wyatt, but I'm encouraged by what you wrote above. To find out that he is eating, talking, and ready to go back to school, and excited about it, that is very encouraging.
Using the words quadriplegic, ventilator, and brain injury in the description of a recently injured human… often that combination of descriptive words is not followed with encouraging news. I'm glad for Wyatt and your family.
