DDmom, that's not good the way his care is being handled. You should have at least been notified that his Coordinator is not there. Where is your transplant center? I wouldn't say this is normal. Members of my transplant team have called and returned calls in a very prompt manner, both to my home phone and cell phone. I have no complaints at all about any of them...except maybe that my hepatologist doesn't want to answer questions or discuss anything without seeing me face-to-face...but I understand the reasons for that.
Perhaps his C-Pap machine needs to have its settings adjusted again.
Be sure you get in touch with someone on Mon.
Hugs,
Connie
