TECHNICAL DIVE BUOYANCY II

There are two maxims for good buoyancy:

Controlled breathing and correct use of the vest.

Any instructor or experienced diver will give you a memorable example: air-filled balloons, but when you lose ascend, descend.

buoyancy system of most fish is based on the swim vegiga :

membranous sac that possess the most fish by the gastrointestinal tract, and allows the fish to swim, float and maintain stability in the water by its swelling with gas. The filling and emptying system is created using a vascularized in which the gases diffuse through a fine network of blood vessels lining the bladder. Once achieved
buoyancy 0, allows the fish to remain stable without spending any energy. It is a unique organ in bony fish, fish not found in Chondrichthyes.

As we do not possess this type of organ in our body, we manage with the lungs and the vest.

controlled breathing.

P ara ascend gradually inspired air, and fill your lungs full or to reach the depth you want. To descend, empty the lungs slowly and you'll make with ease. Remember to make a quiet breath, because if you do it in a jerky fashion, will not reach to fill or empty air your lungs and not experience any rise or descenso.Tampoco have to do so sharply as you can not control the stability and depth properly.

vest Correct use:

should be deflated rapidly in any position. To do so, must use any strings deflation, not only the trachea or fly system. By immersing the trachea only when we loose air air vest and are upright with his head toward the surface. If on the contrary, we are in a horizontal position, the trachea is not useful for anything and we use other airless cords to descend.

The vest is not only deflates; should know when you get to inflate so as not to dive below the depth that is intended and also to avoid bumping against the bottom . Keep in mind that inflate the vest from time to time to reach deeper involves consuming no more air in the bottle , on the contrary, the effort will be made to maintain neutral buoyancy vest unfilled generate a much higher consumption of air.
