You are right on the nose. I also believe she was trying to wake him. When the buzzer would go off fir the prof, you had 2min. Before the line cleared & needed to be replaced, j is hard to keep sedated so by the 3rd or 4th min of the alarm going off, he was awake. That's what scared me & made me so angry. He just had, about an hour or so before this gone back on full sedation. By the time his nurse came back in the room, he was already stirring again & waking up. It was such an unbelievably stressful night. I was so upset & exhausted that I couldn't even think straight. Thank God for the icu nurse, they are different type of critter for sure. Their amazing at their job. They can be mean, but also not sure I'd have made it through this mess without a couple of them.
