Late in the day on Tuesday, June 4th, visitors found a 29-year-old man in severe distress on the North Kaibab Trail. The hiker reportedly drank large amounts of water, but had eaten very little food. This, coupled with the expected increased perspiration while hiking in hot temperatures, lead rangers to believe this visitor was suffering from a potentially life-threatening condition due to low blood sodium levels known as hyponatremia. Responding via helicopter, ranger/medic Brian Bloom utilized a portable blood chemistry instrument (iStat) to confirm his suspicions and begin appropriate field treatment. Due to the serious nature of the man’s condition and the lack of nearby landing zones, he was helicopter short-hauled with Bloom from switchbacks in the Redwall to the North Rim helibase. He was then placed inside the helicopter, flown to the South Rim, and taken from there to Flagstaff Medical Center. Heis expected to recover.
