They note that even if people are generally well prepared, they sometimes struggle to calculate the difficulty and measure the effort. “With the boom in the indoor starment, mountaineering has become very democratic,” notes Grégory. But it is not the same as to make a long way, to manage your effort over time with changing weather conditions. We must increasingly evacuate climbers stuck in a wall. ” Generally people are grateful to see the rescuers arrive. But the two guides note an evolution: “For some, mobilizing a helicopter, a whole rescue team and that we sometimes risk our lives seems completely normal to them. As a due. It questions… ”

Part of the work of a first aid is also the expectation. Between two interventions, the teams can relax. “We discuss, we laugh, we eat together,” explains Pierre-Alexandre ISOZ, paramedic. “But that remains very important. It’s a teamwork. We must know the people with whom we go on a mission. We must be able to count on each other. ”
It is also an opportunity to debrief and empty your bag. “Some rescues can be difficult to live. We have psychological support. But sometimes, it’s easier to tell someone you know about it. ” The rest of the time there is still work. Make administrative, prepare the equipment, look at the weather situation … “I am a bit do everythingsmiles the paramedic Friborg.
