"As Anaesthetists the ultimate goal of almost all of our interventions and monitoring is to support cell energy production to provide mitochondria with the oxygen and the fuel they need to produce enough adenosine triphosphate (ATP) to power cell function and integrity".

How human cells produce energy, how this changes in response to stress and how this may influence survival; this piece focuses what we know about how our bodies get the fuel they need to survive surgery and thrive as a result, providing a positive long term outcome. This is not a piece about nutrition, it's a provocative session exploring concepts designed to provide food for thought.

Presented by Helen McKenna, is in the final year of her PhD at University College London, investigating bioenergetic and redox function in critically ill patients.
