Altitude by liaoqinmei


       Guinness Book of World
   The highest town in the world is
    Wenzhuan, which was founded in 1955 on
    the Qinghai-Tibet road north of the Tangla
    mountain range. It is 16,730 feet above
    sea level.
   The highest capital in the world is Lhasa,
    the former capital of Tibet, with an
    elevation of 12,087 feet above sea level.
             Altitude Dangerous?
   The pressures of altitude and the oxygen
    deficiency in the air, make working at altitudes a
    dangerous place for construction.
   Some symptoms that result from this type of
       Fatigue
       Difficulty Breathing
       Coughing
       Headache
       Drowsiness
       Dizziness
       Nausea
                               Degrees of Altitude

   Mountain medicine recognizes three altitude regions:[4]
   High altitude = 5000 – 11,500 ft
   Very High altitude = 11,500 – 18,000 ft
   Extreme altitude = 18,000 ft – above
   Travel to high altitudes can lead to medical problems, from the mild symptoms of
    acute mountain sickness to the potentially fatal high altitude pulmonary edema
    (HAPE) and high altitude cerebral edema (HACE). These conditions are caused
    by the profound hypoxia associated with travel to high altitudes.[5]
               Altitude Sickness
   Also known as acute mountain sickness (AMS),
    altitude illness, hypobaropathy, or soroche
   It commonly occurs at 8000 feet above sea level, and
    some feel the effects at as low as 6500 feet.
   Symptoms can be experienced 6-10 hours after ascent
    and generally subside in the first 2 days, but they
    occasionally develop into the more serious conditions.
               Altitude Sickness
   Altitude sickness can affect many areas that can
    affect jobsite performance and safety, three main
    areas affected are:
     Mental health
     Physical health

     Sleep habits including sleep deprivation
    High Altitude Pulmonary Edema
 The causes for this disorder result from high blood
  pressure in the lungs, which force fluid into the lung
  tissue, slowing the passage of oxygen from moving
  through the alveoli to the blood.
 Women are of lower risk than men; while teenagers
  and children are more susceptible.
      High Altitude Cerebral Edema
   Is more serious than acute mountain sickness
    but progresses to loss of balance, difficulties
    with walking, clouding of consciousness,
    irrational behavior and coma.
   It occurs rarely to a degree where fluid leaks out
    of capillaries into the brain tissue.
   Respirators may be needed in certain
    circumstances if symptoms persist
   If respirators are needed training is
    necessary for the handling and use of the
    systems in order to comply with OSHA
    and to mitigate dangers associated with
    the systems.
    Symptoms of Altitude Affecting
   Adverse changes in mood states
   Impairment in mental performance
   Fatigue
   Panting
   Dizziness
   Drowsiness
   Nausea
   Weakness
   Headaches
   Persistent dry cough
   Fever
   Vomiting
      Safety Measures at Altitude
   Acclimate before working at higher altitude
   Reduce work pace at higher altitudes
   Avoid smoking
   Avoid drug use of any kind including
   Eat light meals
   Maintain hydration by drinking plenty of
   It may help some people to speed up the
    acclimatization process when taken before
    arriving at altitude
   It can treat mild cases of altitude sickness.
    A typical dose is 250 mg twice daily
    starting the day before moving to altitude.
