Rose,
I think it is a very wise choice to put you in the CICU where you will be monitored closely and the staff ratio to patient is lower. Septicemia is a serious infection so this would be normal to move you to a place that is a better fit to meet your needs at this time.
You can do this and I will say extra prayers for you to help you fight this infection. I believe in you so know you are never alone.
Gentle Hugs,
Kitt
