UGLEKISLOTA. Coal acid anhydride (Acidum carbonicum anhydricum;

      Ñàrbonei dioxydum): CO 2.

     Gas colourless and odourless. In January, five times heavier air. With 60 atm pressure can be turned into liquid at normal temperatures. Liquid coal anhydride is sold in steel cylinders.

     Carbon dioxide has formed in the tissues in the body's metabolism and plays an important role in the regulation of breathing and blood circulation. It has a direct and eucalyptus (through karotidnye klubochki) effect on the respiratory center and is a special agent.

     Inhalation of small concentrations of carbon (3 - 5-7%) is increasing and deepening of the respiratory movement and increase in pulmonary ventilation; Both brought sosudodvigatelnye points, which is narrow blood vessels and increasing blood pressure.

     High Carbon Dioxide is a strong disorders, fatigue, convulsions and paralysis of respiratory center.

     Using carbon dioxide with oxygen in the respiratory center of oppression: the poisoning of volatile funds for anaesthesia, the oxides of carbon, hydrogen sulphide, and newborn asphyxia, etc.

     Earlier in the surgical practice of using general anesthesia during and after surgery to stimulate breathing, for the prevention of lung atelectasis and pneumonia. Inhalation dioxide in the past also used in vascular collapse.

     In sharp weakening of breathing carbon should be made with caution as a result of inadequate ventilation, it can accumulate in the body in excessive quantities. In these cases might aggravate the same as in the application of carbon in high concentrations.

     Liquid carbon dioxide produced from the cylinder, placed downstream valve away from the terms room temperature and normal pressure, evaporates quickly, and absorbed so much heat that it is becoming a firm white snegoobraznuyu mass. This is in the freezing of tissues for histological sections. If mixed solid coal anhydride with air, the temperature drops to 80 'S. "Carbon Snow" is used in treating skin diseases (with red lupus, leproznyh knots, warts, etc.). In education carbon snow, collect it in special bags and then drawing in the moulds of cardboard or glass Bea and put to skin sites to be destroyed. There is evidence of the effectiveness of skin lesions pockets of freezing (cryotherapy) at neyrodermitah.

     Drinks containing dissolved in the form of carbon dioxide (carbonated mineral water, carbonated beverages), cause blood mucosa, and increased secretory, vsasyvatelnuyu motor activity and the gastrointestinal tract.

     Carbon dioxide contained in natural mineral water used for therapeutic baths (eg narzannye baths) can have complex effects on the body, causing a centralization impulses from the skin receptors and the emergence of good changes in the cardiovascular system and other organs, as well as change trofiki tissue.
