12 facts about what happens to you in the open space within 90 seconds
Shot from X / movie "Total Recall", 1990
If all of a sudden, by some miracle, you suddenly find yourself in an almost vacuum of outer space, it will stay alive for about 90 seconds. That is what will happen at this time to your body:
1. For the first 10-15 seconds you remain awake and feel as the moisture evaporates from the tongue. The same happens with the entire surface of the body - as in heavy sweating. Therefore, in the vacuum of space one feels icy cold.
2. There are nausea and vomiting, as gases from the stomach and intestines rapidly pushed out. (Note: before the spacewalk from soda and hot sauces is better to abstain).
3. If the eustachian tubes in the ears are clogged by earwax, or something else, there may be problems with the inner ear, if not - okay.
4. The heart rate increases rapidly, then gradually falls, as well as blood pressure. Venous pressure is growing steadily as the formation of gas bubbles in the body.
5. The body can swell up to the size, twice the usual, the skin is stretched, of course, if you do not wear tight elastic suit.
6. According to the "Collection of data on space biology," precisely fitted elastic garment can completely prevent the formation of gas bubbles when the pressure to 15 Torr (mm Hg). For comparison, normal atmospheric pressure - 760 Torr, and the pressure on the moon - about 10-11 torr. The blood boils at 47 torr. The body is inflated due to the fact that the fluid in the soft tissues passes into the gaseous state. However, the skin is strong enough to withstand this pressure. So, you do not tear apart, you just razduetes like a balloon.
7. As soon as the body pushes steam through the nose and mouth, and the content of fluid in the body decreases, you feel all the more cold. Mouth and tongue become icy.
8. If you find yourself with all this and more in direct sunlight (without special protective equipment), you get a severe sunburn.
9. Due to the lack of oxygen the skin becomes bluish-purple hue, known as cyanosis.
10. The brain and heart remain in the relative order of about 90 seconds. When the blood pressure falls to 47 Torr, the blood begins to boil and the heart gradually stops. Then you nothing will.
11. However, if the pressure is restored in time, the body gradually back to normal. True, for a while you lose eyesight and ability to move. But over time, the two functions will be restored. In addition, a few days you will not feel the taste of food.
12. On the other hand, if you hold your breath or try to interfere with the free passage of air during sudden decompression otherwise, the "increase in intrapulmonary pressure will lead to such a strong expansion of the chest that can cause breaks in the and the destruction of lung capillaries. Withholding the air squeezed out of the lungs in the chest, and through the damaged blood vessels penetrate directly into the bloodstream. And through the bloodstream air bubbles already spread throughout the body and can easily get to vital organs such as the heart and brain. " Something similar could happen during decompression on board the aircraft flying at high altitude. If that happens - remember, hold your breath in any case can not be.
