Pascal Zellner has been an emergency physician since 1994. In 2005, he and Emmanuel Cauchy founded Ifremmont, the mountain medicine research institute based in Chamonix-Mont-Blanc. With their teams, they revolutionized telemedicine for patients in isolated environments. At the time, there was only one solution: a large suitcase from the European Space Agency... They are developing research, prevention and treatments linked in particular to high-mountain pathologies, whether hypoxia (rarefied oxygen) or cold.
At Secret Planet, we've been partners with Ifremmont for many years. As such, we offer several services in conjunction with this world-renowned institute, from medical teleconsultation and personalized medical advice before setting off, to hypoxia testing and preparation, travel medical hotline, guide training and preparation of our participants for our most emblematic treks and expeditions.
In our interview, Eric Bonnem talks to Pascal Zellner, one of the leading field specialists on these subjects, about the origins and medical services offered by Ifremmont, on high-altitude pathologies, acute mountain sickness (AMS) and frostbite, in particular.
Discover our high-mountain expeditions over 7,000 meters and 8,000 meters.
