Machu Picchu Safety Your safety is our top priority. On the mountain, your Leader will carry an expedition first aid kit, a satellite phone and have two-way radio contact with all of our guides at all times. They will also carry a pulse-oximeter to monitor your oxygen levels regularly. In the event of an emergency, helicopter rescue is available and - if your travel insurance covers medical evacuations up to 6,000 meters above sea level - your insurance company should cover your costs. We also carry an emergency supply of supplementary oxygen.
