In that elevation you're not moving fast, and the 100 meters can take you hours to cross. Climbers are exposed under the seracs in the Bottleneck for about 100 meters. The seracs can release sporadically, wiping out an area the climbers have to walk along to reach the summit. On top of the physical and psychological effects of being in extreme elevation, K2 has a section of the climb called "The Bottleneck", a narrow couloir about 400 meters from the summit that is overhung by seracs (blocks of glacier ice) from an ice field east of the summit. Movement is severely slowed down, you can't digest food, you can't sleep, and your reaction times are slowed way down. Above 26,000 feet is often referred to as the "Death Zone". Think about using every ounce of energy you have not only to stand up straight in incredibly volatile weather, but also move forward, while maintaining your tried-and-true systems, safely.Įven with supplemental oxygen, the human body has a limited amount of time it can survive in that elevation. Imagine yourself on an incredibly cold, incredibly windy, super-exposed mountain ridge making decisions that will either keep you alive or not.and your brain is not functioning as an adult brain. Mumbling and moments of blacking out are common. I had the opportunity to be connected with Adrian and his guiding company, Alpenglow Expeditions, back in March and we talked a lot about his decision-making process when in high altitude. Lack of oxygen obviously has a huge impact on your brain. Adrian said that once he reaches a certain altitude, his cognitive ability reverts back to that of about a 2-year-old. (He has had far more successful Everest summits with oxygen.) In April, Carla became the first South American woman to summit Everest without supplemental oxygen. A fortunate weather window opened up yesterday and they went for it, and succeeded.Īdrian has previously summited Everest twice without supplemental oxygen. Sponsored by Eddie Bauer, Ballinger and Perez climbed the Cesen route, along with their teammates, photographer Esteban "Topo" Mena and Pemba Gelje and Palden Namgye all of who carried and used supplemental oxygen for safety. Separately, and shortly before their summit success, Nirmal Purja and his team of sherpas also summited K2, a huge win for his attempt to summit all 14 peaks above 8,000 meters in just 10 months. Consultations with the division’s board-certified physicians are offered in both English and Spanish throughout South Florida.Professional mountaineers Adrian Ballinger and Carla Perez just summited K2, the second-highest mountain in the world, and one of the most dangerous, without supplemental oxygen. The Inflammatory Bowel Disease (IBD) Center provides comprehensive support and management for children and young adults with Crohn’s disease and ulcerative colitis, while the Gastrointestinal (GI) Center offers nutritional assessment and counseling for overweight children, as well as those with dietary restrictions. The team employs a multidisciplinary approach that brings together an array of specialists to deliver personalized care to the patient and family. The Division of Pediatric Gastroenterology at Nicklaus Children’s Hospital is dedicated to the treatment of a wide variety of gastrointestinal problems in children and adolescents. Perez is employed by Nicklaus Children’s Pediatric Specialists, the multispecialty group practice of Nicklaus Children’s Health System. Her work has been published in peer-reviewed journals, she has authored textbook chapters and presented at medical conferences.ĭr. She is a member of the American Academy of Pediatrics and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. Perez is board certified in general pediatrics.
Her clinical interests include eosinophilic esophagitis, aerodigestive disorders and cholestatic liver diseases.ĭr.
She then pursued a fellowship in pediatric gastroenterology, hepatology and nutrition at Baylor College of Medicine/Texas Children’s Hospital in Houston. Perez completed a residency in pediatrics at Nicklaus Children’s Hospital in Miami. She earned her medical degree from the Loma Linda University School of Medicine in Loma Linda, California. Carla Perez is a pediatric gastroenterologist within the Division of Gastroenterology at Nicklaus Children’s Hospital.
