Reliance on Technology Among Climbers on Mount Rainier

Upper-air model of summer balance on Mount Rainier, USA

In 2003–07 summer balance was measured at altitudes between 1700 and 3382ma.s.l. on two glaciers onMount Rainier, Washington State, USA (46.85◦N, 121.72◦W; 4400ma.s.l.): south-facing Nisqually Glacier and east-northeast-facing Emmons Glacier. Upper-air temperatures at the nearest gridpoint in the NCEP/NCAR reanalysis database are used in a distributed (over altitude) positive-degreeday (PDD) mo...

Understanding Human Over-reliance on Technology

An older adult was admitted to hospital with a diagnosis of new-onset seizures. Admission orders included initiation of the anticonvulsant phenytoin (handwritten using the brand name Dilantin), 300 mg orally every evening. Before the pharmacy closed, a pharmacy staff member who was new to the clinical area entered the Dilantin order into the pharmacy computer system, so that the medication coul...

A Chronology of Late Holocene Glacier Fluctuations on Mount Rainier, Washington

Lichenometric studies permit close dating for the timing of stabilization of the late Holocene moraines built by North Mowich, Carbon, Winthrop, Cowlitz, and Ohanapecosh glaciers on Mount Rainier. The moraine chronologies indicate synchronous responses among these glaciers during the past 200 yr. Periods of glacier recession began between 1768-1777, 1823-1830, 1857-1863, 1880-1885, 1902-1903, 1...

Mental Strategies of Elite High Altitude Climbers: Overcoming Adversity on Mount Everest

The physiologic cipher at altitude: telemedicine and real-time monitoring of climbers on Mount Everest.

Advanced wearable biosensors for vital-signs monitoring (physiologic cipher) are available to improve quality of healthcare in hospital, nursing home, and remote environments. The objective of this study was to determine reliability of vital-signs monitoring systems in extreme environments. Three climbers were monitored 24 hours while climbing through Khumbu Icefall. Data were transmitted to Ev...
