Getting ready for my heart assessment

They put these 'nasal prongs' up my nose last night to get me ready for my trip to see the heart specialist in Newcastle.
I wasn't very impressed with the nurse (and I told her as much) but she still insisted on shoving those tubes up my nose!
They tell me that if the specialist is happy with my heart I can come out of this incubator and go into a cot, so that will be a new experience...
