Laws

Boyle's Law- Pressure and volume are inversely related.

Charles's Law- Volume and temperature are directly related.

Dalton's Law- The total pressure of a gas is equal to the sum of the pressures of the individual gases.

Guy Lussac's Law- Pressure and temperature are directly related.

Henry's Law- The amount of gas that dissolves in a liquid is proportional to the partial pressure of that gas

The physics of diving - Boyle's Law

Conditions

"The Bends"

How do you get it? It is the result of not enough decompression after being exposed to increase pressure.

Dangers: Bubbles can grow in tissue and cause local damage.

Side Effects: Joint pain, numbness, fatigue, and possible paralysis.

Treatment: Recompression.

Gas Laws Involved and How They Applies:

Henry's law - If a diver surfaces too fast, there will be too many bubbles from what was high pressure that it will cause "the bends."

Air Embolisms

How do you get it? Occurs when one or more bubbles enter a vein or artery and block it.

Dangers: The air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure.

Side Effects: Difficulty breathing, chest pain or heart failure, muscle or joint pains, stroke, or low blood pressure.

Treatment: Sitting positions, medication, and sometimes surgery to remove embolism.

Gas Laws Involved and How They Apply:

Boyles Law - Air embolisms are created when the volume of the gas increases and expands enough to block arteries because of the increase in pressure.

Oxygen Toxicity

How do you get it? From breathing oxygen at partial pressures.

Dangers: Seizure can result in near death by drowning.

Side Effects: Vomiting, vertigo, lip-twitching, or drowsiness.

Treatment: None

Gas Laws Involved and How They Apply:

Dalton's Law- Oxygen affects them because of the high partial pressure of oxygen explainable by Dalton's Law.
