Xtreme Everest Comes To Radio 4

Among the record numbers of mountaineers on Everest this spring were a team of medics studying the effects of low oxygen levels on the body in one of the world's most icy and precarious science labs.

The team summitted the big E, carrying out a spot of 8000m plus medical research on route, and the good news is that you can find out how they fared in a documentary on radio 4 next Wednesday 1st August.

The hour-long programme is the second of a two-part series, and although the first aired earlier this week, you can still listen to it on the website if you missed out - just follow this link.

Programme one followed the progress of the two hundred research volunteers who trekked to Everest base camp and also pedalled a mile or three on some of the world's most bizarrely positioned exercise bikes. We don't reckon the Exercise Bikes Superstore includes Everest Base Camp in its free delivery offer, but where there's a will there's a way, and the team managed to hoist them up there.

Programme two, airing next week, focuses on the team of medical experts higher up the mountain, including the summit bid, and there's a spot of drama on the bill too - prepare for another Everest rescue.

The experiments were designed to test a new theory about how our organs and cells cope - or don't cope - with oxygen starvation, in the hope of providing better treatment for patients in intensive care in the future.

Hear what the experts have to say about it, along with interviews from the medics and volunteers themselves, next Wednesday at 9pm.
