How (fast or slow) should a scuba diver float from depth to surface?

1. Scuba diver should float slowly.
2. The fluid pressure depends on the depth. It is the larger, the higher the column of water. The concentration of gases dissolved in water is proportional to the pressure in it, so at a depth it is greater than on the surface. These gases are absorbed by the diver’s tissues. When it rises from depth to the surface of the water, the pressure decreases, the gases entering the human body are released. In order for the blood to manage to take away gas bubbles, it is necessary to rise to the surface slowly.
