For the sportsmen that comes from the plain or of places no much height, it’s advisable to be for 2 to 3 days in Puente del Inca.
During the permanence in that zone it could be effected walks and climbs to the neighbouring hills, in order to contributes to a better be accustomed to climate and height. Other alternative, very advisable is dispatch the great charge by means of mules until the encampment base and then the team carry out the distance on foot. To moderate march a walk requires that could take place comfortably in two journeys: the first until Confluencia (Horcones Inferior), and the second until Plaza de Mulas.
After the encampment base is installed, it will be proceeded to perform practices of [aclimatación] and visits to the glaciers of the Horcones Superior and walks for the surroundings. According to the conditions physics could be attempted the ascension of the Cathedral or Cuerno hills; in their defect could move the load to the encampments of height and return to Plaza de Mulas. This practices of ascending and descend to less height benefits notably the [acclimatacion]
According to scientists reports, the period of [acclimatization] change according to the people, the youths are acclimatized worse; the better age is between the 30 and 40 or 45 years old. The nervous equilibrium is very important in the [acclimatization]. Other problem to consider is the descent. If you fall asleep wrong recovers wrong. One must administer very soft [somniferos] If the [acclimatization] is a phenomenon that corrector of the elements on test and always compatible with the life, the adaptation is a hard discipline of the organism that searches for until balance the limits of the possible, the incompatible element with the life: the [rarefaction] of the air, the atmospheric pressure decrease, the cold, the dryness, the [alkalosis], [etc] To superior heights to 6.500 mts. (zone of maximal [acclimatization]), the individual lives only of their reservations, there the necessity of interrupting the stay in on high levels descending to the points where could recover. In this way with the frequent sway, will get and determine the time of maximal permanence in that height without that appears the phenomenons of deterioration, grave sign of alarm.
The “wrong of mountain” is accustomed to manifesting through the following symptoms:
Malestar of headache, nauseates, vomits, decline and sensation of illness.
Brain edema with intense headache, insecure march, mental and visual disorders, nauseates, comma, [etc], pulmonary edema, manifested through respiratory difficulties, [cyanosis], [tachycardia], cough, [restlessness], [etc].
These signs and symptoms are superimposed of like manner that are accustomed to introducing combined. They are stages of a same process and they possess a common nominator: the decrease of the oxygenates in the air.
All these manifestations could be prevented and overcome by means of an adequate [acclimatization]. The knowledge of the signs and symptoms of the “wrong of height“, will permit to the sportsman prevent severe trastorns, included the death, that can ensue in a very brief lapse.
The patient that descends rapidly to minor heights, achieves in general a good recuperation, that which doesn’t occur with that which doesn’t do it on time.
The conduct recommended in such cases is descend to less height upon advising the minimal symptom of illness.

Acute Mountain Sickness (AMS)
Represents the body’s intolerance of the hypoxic (low oxygen) environment at one’s current elevation. Who can get AMS? Anyone who goes to altitude. It is primarily related to rate of ascent. No way been found to predict who is likely to get sick at altitude. In the context of a recent ascent, a headache, with any one or more of the following symptoms above 2500 meters (8000 feet) qualifies you for the diagnosis of AMS:

  • Loss of appetite, nausea, or vomiting
  • Fatigue or weakness
  • Dizziness or light-headedness
  • Difficulty sleeping
  • Confusion

Staggering gait It is remarkable how many people mistakenly believe that a headache at altitude is “normal” when it is actually AMS. Be willing to admit that you have altitude illness. The key to avoiding AMS is a rational ascent that gives your body time to acclimatize.

Things to Avoid
Respiratory depression (the slowing down of breathing) can be caused by various medications, and may be a problem at altitude. The following medications can do this, and should never be used by someone who has symptoms of altitude illness (these may be safe in non-ill persons, although this remains controversial):

  • Alcohol
  • Sleeping pills (acetazolamide is the sleeping tablet of choice at altitude)
  • Narcotic pain medications in more than modest doses
