Following SCUBA Diving Safety Laws

By: Cienna Newett

Boyle's Law

This law states that when the pressure of a gas decreases, the volume increases.

Charles's Law

This law explains how gas can expand when it's heated up.

Dalton's Law

In a mixture of gases, the total pressure released is equal to the sum of the partial pressures.

Gay-Lussac's Law

If temperature increases, pressure increases in a container.

Henry's Law

The mass of a gas which can dissolve in a solution that is proportional to the partial pressure of that gas in equilibrium with that liquid.

The Bends

How does this happen?

When a diver comes up too quickly to the surface.

Dangers

serious cases can cause a coma or death

Side Effects

joint, arm, and leg pain

dizziness

Treating the Condition

Take the person back to the depth they were diving at to force the bubbles to resolve into the blood. This immediately solves of the symptoms of the condition.

Gas Law

Boyle's and Charles's Law because gas is expanding within the SCUBA suit.

Air Embolisms

How does this happen?

Air Embolisms occur when one or more air bubbles enter a vein or artery and block it.

Dangers

coma or death

Effects

Causes the air sacs in your lungs to rupture

Treating the Condition

To treat this condition you must administer oxygen, and put the diver in a slanted position head facing down. This slows the heart rate until the diver arrives at the hospital.

Law

Boyle's Law relates to this condition because it involves unequal pressures withing the SCUBA suit.

Oxygen Toxicity

How does this happen?

This condition occurs when breathing molecular oxygen.

Dangers

Hyperoxia- excess oxygen in lungs

Side Effects

disorientation

breathing problems

vision changes

How to treat the condition

Therapeutic decompression and hyperventilation

Gas Law

This relates to Dalton's Law because the partial pressure of all component gases increase in the same ratio as the total pressure.
