Continuation oft the Jena high altitude experiment in the high Alps





On the first weekend of October, 2014, a unusual experiment took place at the Berghaus Diavolezza in the Upper Engadine, Switzerland, at 3,000 meters altitude. 20 Doctors of the Jena University Hospital, including cardiologists, angiologists and rheumatologists wanted to collect insights into the adaptation of the organism at high altitude in a high altitude experiment. Under special observation was the adaptation of vascular regulation to the lower oxygen concentration. These regulatory mechanisms are important in pulmonary hypertension, a disease that can lead to significant problems of the cardiovascular system.In the centre of the studies was the question how does a medication that joins to an endothelin receptor influence the vessel reaction at high altitude. A station in the study protocol of the experiment was to measure the retinal vascular function with the Dynamic Vessel Analyzer (DVA) from IMEDOS Systems UG. The accompaniment of the demanding transport by cable car to 3,000 meters altitude and the construction of the apparatus were supported by Gerald Floßmann of IMEDOS. The data for the measurement of intraocular venous pressure by Michael Baertschi, Optometrist and an expert in the field of glaucoma research from the University of Basel, will help in the evaluation of the experiment to better understand the retinal circulation at high altitude. The results of this ambitious high altitude research project are currently being evaluated and will be reported.
