Hi just had a call to say she may be moved to ICU as she is on high levels of oxygen what does this mean? How serious is this? What are her chances? I have read online but need more. I'm at home tonight after being there all day she is talking and positive doctors are just telling me facts that I don't understand on a scale of 1-10! I'm home now and not sure if I should be going to work tomorrow or going to stay at hospital my mum is my best friend please help shed some light.
