3.+Survival+Tips

__Medicine:__

1. Breathing Problems
Any one of the following can cause airway obstruction, resulting in stopped breathing:
 * Foreign matter in mouth of throat that obstructs the opening to the trachea.
 * Face or neck injuries.
 * Inflammation and swelling of mouth and throat caused by inhaling smoke, flames, and irritating vapors or by an allergic reaction.

2. Control Bleeding
In a survival situation, you must control serious bleeding immediately because replacement fluids normally are not available and the victim can die within a matter of minutes. External bleeding falls into the following classifications (according to its source): You can control external bleeding by direct pressure, indirect (pressure points) pressure, elevation, digital ligation, or tourniquet.
 * Arterial. Blood vessels called arteries carry blood away from the heart and through the body. A cut artery issues //bright red// blood from the wound in //distinct spurts// or pulses that correspond to the rhythm of the heartbeat. Because the blood in the arteries is under high pressure, an individual can lose a large volume of blood in a short period when damage to an artery of significant size occurs. Therefore, arterial bleeding is the most serious type of bleeding. If not controlled promptly, it can be fatal.
 * Venous. Venous blood is blood that is returning to the heart through blood vessels called veins. A steady flow of //dark red, maroon, or bluish// //blood// characterizes bleeding from a vein. You can usually control venous bleeding more easily than arterial bleeding.
 * Capillary. The capillaries are the extremely small vessels that connect the arteries with the veins. Capillary bleeding most commonly occurs in minor cuts and scrapes. This type of bleeding is not difficult to control.

__Water:__

Water is one of your most urgent needs in a survival situation. You can' t live long without it, especially in hot areas where you lose water rapidly through perspiration. Even in cold areas, you need a minimum of 2 liters of water each day to maintain efficiency

Green bamboo thickets are an excellent source of fresh water. Water from green bamboo is clear and odorless. To get the water, bend a green bamboo stalk, tie it down, and cut off the top. The water will drip freely during the night. Old, cracked bamboo may contain water. ​
