Sphygmomanometer (thanks AP).

Be doo, be doo be.

On another note, I took my 'When you're a stranger' photo this morning of a lovely member of UCHG catering staff called Stacey. Stacey is from Galway, doing teacher training in Limerick during the week and then working in the hospital at weekends. She was happy to pose for me so I hope the photo works out ok. Not used to these disposable cameras!!
