Hi Hope this isnt too late but i've not long qualified and had my elective at the CardioThoracic Centre in Liverpool.
Plenty of patients to see, and in addition the amount of in-service training is second-to-none...it was almost daily when i was there in April 2005!!
They will also help you see particular things you want to if you ask.
Maggie or Jay are the two people to speak to in the Respiratory Physio Department.
Hope this helps
Paul
