Chuck had a couple more "episodes" this evening. His heart did not stop, but he was not able to breath well on the vent. He kept throwing mucus plugs. When they took Chuck off the vent and bagged him, he breathed easier. Christe and Shea sent me home around 6:45 while they stayed to make sure Chuck stabilized.
The decision was made to try a new trache. This one is larger in diameter with a longer shaft. Thus far, it has worked beautifully.
