Abstract:
This research will be an overview about what are the pressure related dangers of scuba diving, how do these dangers happen, how to prevent those dangers and the identification of their symptoms.
Introduction: A form of underwater diving with the use of breathing apparatus to breathe underwater is Scuba Diving. Great freedom of movement and longer underwater endurance can be felt for diving with their own or personal source of breathing gas which contains compressed air rather than breath hold. This means that it is different from other forms of diving where they have a wire or cord connect above ground to supply air to breathe. External propulsion is provided from the diver propulsion vehicle, or a shed pulled from the surface and a scuba diver can also move around manually by the fins attached to the feet. However, scuba divers must always have to keep in mind that scuba diving is an extreme and dangerous sport where dangers come from the effect of the increased water pressure of sea environment, making it potentially life threatening. Dangers can also be from the sea …show more content…
Thus, as we descent, the pressure surely will increase. Our air-filled spaces like the mouth, ears, para-nasal sinuses and lungs will be exposed to danger. This is because the air in air-fill spaces will expand when we descend.
Pressure increase with depth
Pressure will be exerted on a diver’s body by his own weight. The deeper he dives, the more water above him, thus having greater pressure exerted. Total Pressure = P(water above him) + P(air above him)
Every 33 feet of seawater = 1 ATA of pressure
Water pressure compresses air
The air in a diver’s body air spaces and diving gear would be compressed as pressure increase and vice versa. Air would compress according to Boyle’s Law shown below.
Boyle’s Law: Air Volume =
