Physical Training and Medical Info
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,
-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
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):
Sleeping pills (acetazolamide is the sleeping tablet of choice at altitude)
Narcotic pain medications in more than modest doses
The group of disorders is characterized by:
> Headache in 96% of cases.
> Insomnia in 70% of cases.
> Loss of appetite in 38% of cases.
> Nausea in 35% of cases.
> Difficulty breathing, dry cough, and vertigo are also frequent.
This poor adaptation can in the same way translate into localized edemas in the eyes, face, hands, and ankles. Some affected people also produce less urine (oliguria). Recognizing this problem early and making a early diagnosis avoids grave complications. As soon as some simple symptoms are recognized, one can know how much they have been affected by the altitude and what action to take.
First, verify if you suffer from any of the symptoms, and then use the following table to know how much you have been effected by Acute Altitude sickness.
Altitude sickness is a complex syndrome, described in the Andean plateaus as "The sickness of the plateaus" by José de Acosta in 1590. Over 100 years ago Paul Bert demonstrated the importance of hypoxia in its beginning stages.
As you ascend, the air becomes scarce and the global barometric pressure, as well as the partial pressure, of oxygen and water vapor, diminish. For this reason, the hypobaria associated with hypoxia and dryness appear.
The climb to the mountain heights unleashes a cascade of biophysical actions:
There is a progressive cooling of 1 degree Celsius for every 200 meters climbed, which diminishes the protective effects of the atmosphere, which increases the intensity of solar radiation during the day, while the lower levels of irradiation cause the nights to be more cold, resulting in the increase in intensity of the atmospheric phenomenons.
In the mountain heights, because of hypobaria, it is common for the nasal sinuses to drain, characterized by the uncomfortable obstruction of the nostrils. This situation obliges us to breathe through the mouth, which in turn increases the sensation of shortness of breath, which is complicated by the increased feeling of thirst, a product of the drying of the upper respiratory mucose membranes. On the other hand, because of the swelling of the bases in the digestive tube (aerogastria and aerocolia), dyspepsia and loss of appetite are added to the discomfort.
The dryness causes intense thirst and difficulty in swallowing.
The skin is also affected as it loses its elasticity and is made more sensitive to scratches, sunburn and radiation, and cold. There is a progressive cooling of 1 degree Celsius for every 200 meters climbed, which diminishes the protective effects of the atmosphere, which increases the intensity of solar radiation during the day, while the lower levels of irradiation cause the nights to be colder, resulting ina deepening in intensity of the atmospheric phenomenona.
The most notable symptoms of altitude sickness are created by hypoxia.
The organism reacts reflexively, activating the central nervous system and increasing the consumption of energy.
Shortness of breath and increased heart rate appear, which have their physiological limit; in the heart, this limit is discovered to be around the frequency of the equivalent of 200 below the age in years, because above this value the efficiency of pumping is lost.
Even more complex and interesting is the result ofshortness of breath; in the beginning it allows for the increased amount of air to arrive to the lung alveoli, which assures the correct oxygenation of the blood, but as the frequency of breathing increases, it produces hyperventilation and a depletion of CO2 (Carbon Dioxide). In this way, the ambient hypoxia (due to lack of oxygen in the air) tries to be compensated by an alveolar hypocapnia (in the lungs).
On the other hand, the lowering of partial pressure of carbon dioxide deprives the respiratory system of the physiological stimulus, with the final result being the necessity of voluntary respiration, even more fatiguing than the habitual reflexive breathing, which aggravates the prevailing feeling of shortness of breath; on top of that, the difficulty of maintaining voluntary respiration produces a strange form of insomnia.
The climber wakes up various times while sleeping due to dizzy spells created by momentary lack of respiration. In these conditions, the prescription of tranquilizers doesn't have any effect on the actual causes of insomnia and, on the contrary, can convert these night-time labored breathing spells to a grave crisis of apnea.
