British doctor drops trousers on Everest
At 27,559ft in winds blowing above 20-knots a British doctor drops his trousers not out of any sexual need to expose his privates to the elements on the highest mountain in the world but in the name of medical science.
Blood was taken and he was found to have the lowest ever blood oxygen level ever recorded.
The doctor was part of a team trying to find better treatments for patients with amongst other diseases, acute respiratory distress syndrome, cystic fibrosis and blue baby syndrome.
It may have been -25C, but one mountaineering doctor dropped his trousers on Everest and measured his blood oxygen level to find new treatments for his patients.
Anaesthetist Daniel Martin, who had a sample taken from his leg artery just 400m from the summit of the world's highest peak, was found to have the lowest blood oxygen level ever recorded.
His bloody oxygen measurement was previously thought to be incompatible with life, but despite this Dr Martin was walking and able to take samples from his nine mountaineering colleagues.
