Jarle was accompanied by another Norwegian team comprising Lars Oma Erichsrud and Petter Lindén Nyquist, who reach the top 22nd May.
There are reports of climbers in trouble being helped down on both sides, with the most serious case being that of Jarle Traa, reported to be found in a critical condition on the North side ABC.
Over 8000 metres there is 30 % lower volume oxygen than by the ocean level. So it`s incredlible that Jarle made it to the top without extra supply of oxygen.
Jarle Trå has now arrived a hospital in Nepal and will be threaten there, according to Norwegian media (TV2 and Nettavisen).

A Sherpa named Babu has climbed Mount Everest 7 times without oxygen.
Advice from the international expedition portal ExplorersWeb:
Do not attempt Everest without oxygen, unless you are an experienced +8000-meter/26000 ft climber, with at least one previous experience at 8500-meters/28000 ft without oz. Your sherpa should carry a spare oxygen bottle for emergency. And remember to drink plenty of fluids. Link for more information on ExplorersWeb`s website: http://www.mounteverest.net/expguide/wwoz.htm
