  • 8,000 feet
  • Descents are part of normal procedures, but also occur during emergencies, such as rapid or explosive decompression, forcing an emergency descent to below 10,000 feet (3,000 m) and preferably below 8,000 feet (2,400 m), respectively the maximum temporary safe altitude for an unpressurized aircraft and the maximum safe altitude for extended duration. (wikipedia.org)

  • diver
  • the reduction of ambient pressure on underwater divers after hyperbaric exposure and the elimination of dissolved gases from the diver's tissues The decompression of a diver is the reduction in ambient pressure experienced during ascent from depth. (wikipedia.org)
  • Decompression in the context of diving derives from the reduction in ambient pressure experienced by the diver during the ascent at the end of a dive or hyperbaric exposure and refers to both the reduction in pressure and the process of allowing dissolved inert gases to be eliminated from the tissues during this reduction in pressure. (wikipedia.org)
  • ascent Part of the dive profile where the diver is moving upwards towards the surface. (wikipedia.org)
  • An ascent may be interrupted by stops (q.v.), when the diver maintains a functionally constant depth for the purpose of decompression, and pulls (q.v.), during which periods there is consistently upwards movement (minor variations in the scale of a few seconds are generally ignored). (wikipedia.org)
  • exposures
  • The descent, bottom time and ascent are sectors common to all dives and hyperbaric exposures. (wikipedia.org)
  • Fortunately he was using a photographic telescope, and was able to obtain some 500 exposures, as results from more traditional visual methods (meridian line or micrometre measurements) would have been far less conclusive. (wikipedia.org)
  • bubbles

  • 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)
  • occupants
  • 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)
  • 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)
  • caisson
  • 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)
  • acclimatise
  • There are various preventative measures, the most important being slow ascent so that your body can adjust to conditions at the right pace (acclimatise). (patient.info)
  • After a few days, your body starts to adjust (acclimatise) to the higher level of altitude that you are at. (patient.info)
  • climb
  • This climb, initiated by Horace-Bénédict de Saussure, who gave a reward for the successful ascent, traditionally marks the start of modern mountaineering. (wikipedia.org)
  • A descent during air travel is any portion where an aircraft decreases altitude, and is the opposite of an ascent or climb. (wikipedia.org)
  • exposure
  • Its potential severity has driven much research to prevent it and divers almost universally use dive tables or dive computers to limit their exposure and to control their ascent speed. (wikipedia.org)
  • descend
  • This is particularly the case if the signs are not recognised and the person does not move down (descend) to a lower altitude. (patient.info)
  • If your symptoms are severe, do not improve, or they are getting worse, you need to descend to a lower altitude. (patient.info)
  • symptoms
  • For most people, it causes mild symptoms that improve with rest and time spent getting used to altitude. (patient.info)
  • The most important treatment if you develop symptoms of altitude sickness is to stop your ascent and rest. (patient.info)
  • Because of these changes in your body, there are some 'normal' symptoms that you will notice at higher altitudes while your body is acclimatising and adjusting to the reduced availability of oxygen. (patient.info)
  • stops
  • 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)
  • 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)
  • Staged decompression may include deep stops depending on the theoretical model used for calculating the ascent schedule. (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)
  • 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)

  • gases
  • 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 Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km (500 mi) arc from east to west and is 200 km (120 mi) in width. (wikipedia.org)
  • particularly
  • 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)
  • The approach to the mountain from both Nepal and Tibet is easy, and the ascent through Tibet is not particularly difficult. (nepaltrekkingpass.com)
  • 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.
