Summary

The aim of the project "High Altitude Medical Research Expedition Himlung 2013" (HiReach2013) is to comprehensively investigate the cerebral, cardiovascular and pulmonary adaptation and the reactions of the human immune system during an ascent to extreme altitudes of over 7000 m. A total of 44 healthy and trained volunteers will be included in the study after written informed consent has been obtained.Baseline sea level clinical examination will be performed in Bern, Switzerland (BE1) at 550 m 8 to 4 weeks before departure. High altitude research facilities will be available at the altitudes of 5000m, 6100m and 6900m. Post-expedition examination will be performed within 2 to 6 weeks after the end of the expedition in Bern. In the context of 3 sub-projects specific measurements and examinations are performed.

These include: cMRI before and after the climb and neurovascular doppler examination during the climb; blood sampling for coagulation studies, cardiac and thoracic ultrasound, stress tests for assessment of cardiovascular performance.
