British Services Dhaulagiri Medical Research Expedition

This was part of a much larger Joint Services expedition to the Dhaulagiri region, and involved the establishment of mechanisms associated with the development of Acute Mountain Sickness, and assessing the effectiveness of pre-acclimatisation strategies in reducing the occurrence of AMS. The occurrence of AMS among the military deployed at high altitude can affect military performance. A total of 129 personnel took part in the expedition, and were invited to consent to a variety of studies investigating adaptation to high altitude and diagnosis of altitude illness.
