Laws
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
Conditions
"The Bends"
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
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
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.
