• 1500
  • During our approach to basecamp at "Plaza de Mulas", we gradually ascend 1500 metres/5000 feet, over 3 days. (summitclimb.com)
  • The trail then descends approximately 1000 metres including an irregular staircase of approximately 1500 steps, some of which were carved into solid granite. (wikipedia.org)
  • bubbles
  • arterial bubble model Decompression model in which the filtering capacity of the lung is assumed to have a threshold radius of the size of a red blood cell and sufficiently small decompression bubbles can pass to the arterial side, especially during the initial phase of ascent. (wikipedia.org)
  • occupants
  • In the case of underwater diving and compressed air work, this mostly involves ambient pressures greater than the local surface pressure-but astronauts, high altitude mountaineers, and occupants of unpressurized aircraft, are exposed to ambient pressures less than standard sea level atmospheric pressure. (wikipedia.org)
  • The primary means to ensure occupant survivability rests in quickly bringing the occupants to a cabin pressure where they can survive (i.e., a lower cabin pressure altitude as given in the table below). (wikipedia.org)
  • Airplane DAH should use design features that facilitate rapid airplane descent from high altitudes to ensure that the occupants will not be subjected to pressure altitudes for durations longer than those given in the following table. (wikipedia.org)
  • Everest
  • While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, and wind, as well as significant hazards from avalanches and the Khumbu Icefall. (wikipedia.org)
  • Tenzing Norgay and Edmund Hillary made the first official ascent of Everest in 1953, using the southeast ridge route. (wikipedia.org)
  • Peaks, Cho Oyu is the second only to Everest in both the number of Expeditions successful ascents for more than 1600 climbers climbed till to spring 2009. (nepaltrekkingpass.com)
  • 1] Cho Oyu was the fifth 8000 meter peak to be climbed, after Annapurna in June 1950, Mount Everest in May 1953, Nanga Parbat in July 1953 and K2 in July 1954. (nepaltrekkingpass.com)
  • Nepal has the elevation of 8848 meters, which is Mt. Everest, and regions which has elevation of 60 meters squeezed into 500 kilometers making it culturally, geographically and naturally diverse. (wikitravel.org)
  • peak
  • The Chinese mountaineering team of Wang Fuzhou, Gonpo, and Qu Yinhua made the first reported ascent of the peak from the north ridge on 25 May 1960. (wikipedia.org)
  • In 1997, a re-survey using satellite technology established its summit (known as Low's Peak) height at 4,095 metres (13,435 ft) above sea level, which is some 6 metres (20 ft) less than the previously thought and hitherto published figure of 4,101 metres (13,455 ft). (wikipedia.org)
  • aircraft
  • The aircraft would then dive at a 60-90° angle, holding a constant speed of 500 to 600 kilometres per hour (310 to 370 mph), until it had gone some 90% of the way to the ground, releasing its bombs at a minimum height of 450 metres (1,480 ft). (wikipedia.org)
  • DCS most commonly refers to problems arising from underwater diving decompression (i.e., during ascent), but may be experienced in other depressurisation events such as emerging from a caisson, flying in an unpressurised aircraft at altitude, and extravehicular activity from spacecraft. (wikipedia.org)
  • meters
  • Kalinchowk is located northeast direction from Katmandu lie at an altitude of 3579 meters one can get excellent view of Annapurna, Lamjung, Manaslu, Ganesh Himal, Shishapanga, Langtang, Dorjee Lakpa, Jugal Himal and Gauri Shanker. (nepaltrekkingpass.com)
  • ambient pressure
  • During ascent, the ambient pressure is reduced, and at some stage the inert gases dissolved in any given tissue will be at a higher concentration than the equilibrium state and start to diffuse out again. (wikipedia.org)
  • The ambient pressure underwater increases by 1 standard atmosphere (100 kPa) for every 10 metres (33 ft) of depth. (wikipedia.org)
  • known
  • What is commonly known as no-decompression diving, or more accurately no-stop decompression, relies on limiting ascent rate for avoidance of excessive bubble formation. (wikipedia.org)

  • elimination
  • A staged decompression is interrupted by decompression stops at calculated depth intervals, but the entire ascent is actually part of the decompression and the ascent rate is critical to harmless elimination of inert gas. (wikipedia.org)
  • rate
  • A no-decompression dive, or more accurately, a dive with no-stop decompression, relies on limiting the ascent rate for avoidance of excessive bubble formation. (wikipedia.org)
  • For example, tables using Bühlmann's algorithm define bottom time as the elapsed time between leaving the surface and the start of the final ascent at 10 metres per minute, and if the ascent rate is slower, then the whole of the ascent time needs to be considered part of the bottom time for the algorithm to remain safe. (wikipedia.org)
  • Intentional descents might be undertaken to land, avoid other air traffic or poor flight conditions (turbulence, icing conditions, or bad weather), clouds (particularly under visual flight rules), to see something lower, to enter warmer air (see adiabatic lapse rate), or to take advantage of wind direction of a different altitude, particularly with balloons. (wikipedia.org)
  • maximum
  • A maximum of 500 people are allowed on the trail each day, of which only 200 are trekkers, the rest being guides and porters. (wikipedia.org)
  • usually
  • Nevertheless, all currently popular decompression procedures advise a 'safety stop' additional to any stops required by the algorithm, usually of about three to five minutes at 3 to 6 metres (10 to 20 ft), even on an otherwise continuous no-stop ascent. (wikipedia.org)
  • condition
  • The recent reports by the media on two Singaporeans - 66-year-old man and a 61-year-old woman who died of altitude sickness at Mt Kailash - have generated tremendous interest and awareness of this condition. (ezyhealth.com)
