Provide disaster relief and prevent and cure indispensable general knowledge of altitude sickness in cajaput antidetonation of Qinghai
Wired the expert: Wang Hai, the doctor of medicine, researcher, 3 grades of professional techniques, military chief of hygiene environmental medicine research institute of academy of medical sciences, doctoral supervisor. Obtain the national natural science 1 second prize, army and 5 items of first prize of scientific and technological progress at provincial and ministerial levels, authorize 18 of patent for invention, win the intersection of General Logistics Department and scientific and technological the Venus, the entire PLA loves the smart military model of the army, it is rewarded that national Seeking Truth is remarkable and young.
Background: Cajaput seismic zone over 4493 meters above the sea level on average, oxygen content have the intersection of plain and 55% of area only, acute morbidity of altitude sickness can up to 60% or more. On one hand, the team providing disaster relief from plain has not taken the precautionary measures, the radical plateau by air, the organism does not have sufficient time to suit to the hypoxia. On the other hand, the local temperature is very low, with the sleet weather, it is flexible fast to rescue the team, the work load is large, it is overtired, does not have enough sleep that appear, the organism immunity is low, apt to catch a cold, and cold is the important inducement of serious disease and acute altitude sickness. So, how to avoid and positive effectively should be the important topic instantly to acute altitude sickness. Today, staff reporter the intersection of telephone and special visit provide disaster relief a gleam of researcher Wang Hai fighting bravely the intersection of cajaput and antidetonation.
Reporter: After coming from all parts of the country's rescuing radical Qinghai-Tibet Plateau of strength and participating in cajaput antidetonation and providing disaster relief, what changes will the organism which rescues team members have?
Wang Hai: The air of seismic zone of the cajaput is thin, average annual temperature is 2.9 , it is the typical plateau puna. At present, the team providing disaster relief of antidetonation is in initial stage of being concentrated the plateau fast by the plain, because plateau hypoxia, drying, gale,etc. influence, the changes of eight respects will happen in physiological functions of the organism organ.
First, the respiratory rate is accelerated. Because the air is thin, the oxygen content is reduced, enables thereupon reducing of partial pressure of oxygen in people's alveolus partial pressure of oxygen and arterial blood. The human body is in order to get enough oxygen from the external world, must realize through increasing the keeping in touch with amount of lung. Mainly shown as the respiratory rate is accelerated, breathed and strengthened, in order to meet normal physiological demand of the organism, after adapting to the environment, the respiratory rate can prone to resuming.
Second, the heartbeat is accelerated. The heartbeat of normal people is 60- 80 times every minute, garrison in the highland rapidly, the heartbeat is accelerated, about 100 times every minute, and increase fast with high-level rising above sea level. Persons who reach the plateau for the first time, make adequate preparations, appropriate rest, guarantee the sufficient sleep and have meal normally, homework movements should do things within the limits of one's own resources, avoid moving about vigorously, try hard to reduce physical power and mental labour, do the activity of deeplying breathe at the uniform velocity, practise the clothes to plateau environment with the organism, the heart rate will resume and take a favorable turn gradually.
Third, abdominal distension and indigestion. Because the atmosphere pressure in the plateau is reduced, the pressure within the organism is thereupon reducing, cause the stomach to empty time to lengthen, form the bloated air of gastrointestinal tract. So, the persons who enter the plateau of the majority for the first time often feel abdominal distension of chest is full and uncomfortable, the appetite fails, indigestion is weak, disgusting, vomit, even suffer from diarrhoea etc.. After practising the clothes the plateau of about one week generally, will lighten and disappear gradually.
