Presser Feet

As you drop down the underwater world will be affected by pressure changes.

Increase underwater, the pressure of a bar every 10 meters Mts/33, but as divers we can not ignore the atmospheric pressure to it as a bar / atm add. This means that at 10 feet Mts/33 the surrounding pressure of 2 bar / atm.

As we rise and fall of pressure per volume of air through these pressure changes will not be affected. The volume ariDecrease the surrounding pressure increases.

At the same time, the density is also affected by pressure. Density increases with increasing pressure.

As a diver it is important to understand these changes, because they affect us directly, while under water.

As you descend, there is increasing pressure on both ears and lungs, because air spaces in our bodies. The increase in pressure will have an impact on our airConsumption is lower than that we need more air, because the volume of our lungs hold down lower in proportion to the number of bars or atmospheres at a certain depth.

As we grow under the water, reducing pressure on the ear areas of the body (ears and lungs), it is necessary to compensate for the ambient pressure under water.

To compensate for our ears, we can gently pinch the nose and blow holes. what should we do this every 1 meter / 3 feet, as you descend,before you feel any discomfort. If you feel pain as you go, we disappear for a few meters to complaints, and then try again balance our ears.

To compensate for our lungs, we just keep breathing. In fact, breathing is the number one rule in diving. Hold your breath while diving can cause severe lung damage.
