Ysbyty Gwynedd, Bangor early warning screen - how it works

It looks like a large plasma TV in your living room, but this screen in a hospital in north Wales is already helping to save lives.

It is the face of an electronic early warning system which is alerting nurses and doctors to sudden changes in patients' conditions quicker.

The "scoreboard" in two wards at Ysbyty Gwynedd in Bangor records vital signs such as heart and respiratory rates.

A 80% drop in cardiac arrests was recorded under the new system.
