Employing groundbreaking xenon gas therapy, the celebrated alpinist Lukas Furtenbach spearheaded a British expedition to achieve a remarkably swift ascent of Mount Everest, sparking considerable debate and prompting scrutiny from Nepalese mountaineering regulatory bodies concerning the unproven efficacy and potential ramifications of the treatment; the team, having departed London on May 16th, summited the peak on May 21st, and repatriated themselves a mere two days thereafter, while Furtenbach contends that this expedited approach, facilitated by rigorous pre-acclimatisation in hypoxia chambers and subsequent xenon gas infusions at a German medical facility, minimises ecological degradation, specifically curtailing the accumulation of human detritus, he vehemently maintains the safety of the procedure, clarifying that the xenon gas administration occurred extranepal and offering to substantiate its benign effects on climbers' physiological well-being.
