While working as a Peace Corps Response Volunteer in El Salvador in 2007, I was assisting a Salvadoran NGO in first aid instruction to rural community rescue brigades. During one such demonstration word came from another community further up the road that a young man had been injured by a machete while working in the fields. Since we had the first aid materials in the class, my students and I were able to provide a clean field dressing to the wound before the young man was taken to a clinic about two hours away down a rural, winding dirt road.
