At some point everyone reaches his or her limits. That’s true for healthy people and ventilation patients alike. But where exactly are those limits? In the head, the body or the world outside? Is there really nothing more beyond the limits? We seldom know for sure and have to venture forth and test ourselves. This Website tells the stories of Lars, Bianca and Mia, people who always go beyond their limits. And the story of LUISA, the new, high-performance ventilator that accompanies them. If necessary, to the heavy metal festival in Wacken – or to Antartica.
