Which gas law best describes the mechanical compression of bubbles during hyperbaric treatment for DCS?
Charles's law
Boyle's law
Dalton's law
Henry's law
The correct answer is: Boyle's law
The scenario of mechanical compression of bubbles during hyperbaric treatment for decompression sickness (DCS) is aptly described by Boyle's law. This law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant. In the context of hyperbaric treatment, as the surrounding pressure increases (such as in a hyperbaric chamber), the volume of gas bubbles decreases. This principle is vital in managing DCS, as it helps in the reduction of gas bubble size that can occur in the bloodstream or tissues after a diver ascends too quickly. During hyperbaric therapy, the increased pressure aids in dissolving nitrogen into the bloodstream and promotes the elimination of bubbles. Understanding Boyle's law is critical for safely navigating pressure changes and ensuring the effectiveness of the treatment for decompression sickness.
