KATHMANDU, Nepal — An American climber who fulfilled his dream of climbing the highest mountains on each of the seven continents died of probable altitude sickness on the way down from Mount Everest, mountaineering officials said.
Don Cash became ill at the summit and was treated there by his two Sherpa guides, Pasang Tenje Sherpa, head of Pioneer Adventure, which provided the guides, said Friday.
"When he was on the top he just fell. The two Sherpas who were with him gave CPR and massages," he said. "After that he woke up, then near Hillary Step he fell down again in the same manner, which means he got high altitude sickness."
Altitude sickness is caused by low amounts of oxygen at high elevation and can cause headaches, vomiting, shortness of breath and mental confusion.
The Press Trust of India news agency reported Friday that two more Indian climbers died on Mount Everest together with an Austrian while descending from the summit this week.
Also, the U.K.-based climbing company 360 Expeditions said that an Irish climber died Friday while attempting to climb Everest.
They were part of hundreds of foreigners and their Sherpa guides attempting to scale Everest and other Himalayan peaks during the popular spring climbing season, when only a few windows of good weather each May allow them the best chance of success.
Cash, 55, from Utah, had a long-held dream to climb the seven summits — the highest mountains on the seven continents — his daughter Danielle Cook posted on Facebook on Wednesday.
