Use of Xenon gas, believed to help prevent altitude sickness, reduce low-oxygen effects, stirs debate in mountaineering community - Anadolu Ajansı

A British climber who scaled Mount Everest for the 19th time, breaking his own record for the most ascents of the world’s highest peak by a non-Sherpa guide, says he is already planning his next attempt.

Four British climbers became the first to scale Mount Everest on Wednesday using Xenon gas, which helped them save several weeks that mountaineers need to get used to high altitudes, an official of their expedition organising company said.
