Mel Brown has just come to the end of her shift as clinical lead nurse for the trauma care and resuscitation team.
She says the past two days - on course to be the busiest in the unit's short history - show what strain the hospital could be under this summer.
"And it's not even the holidays yet," she adds.
The combination of GP referrals and patients coming straight to A&E with the expectation of a quick fix only adds to the pressure on resources.
"In some ways we're a victim of our own success," says Mel.
And the build up of major trauma patients arriving in the last few hours means the night shift will be even busier.
