Southampton scientists climb Everest for study

Scientists and medical staff from Southampton are tackling one of the harshest environments in the world to study the impact of low oxygen levels on the human body.

The University of Southampton team has travelled to Nepal to carry out vital research into hypoxia - which is a common problem for patients in intensive care.

They are climbing to base camp of Mount Everest.

The scientists hope the expedition will give them a better understanding of why the condition can lead to death.
