Gas Laws

Description

Anesthesiologists deal with liquids and gases under pressure at varying temperatures and volumes.  These inter relationships are simple,measurable and their understanding ensures a safe outcome for patient. The origins of the gas laws came out of experimental work conducted during the seventeenth and eighteenth centuries by several people. These experiments ultimately gave us the three gas laws, and the theoretical construct that arises from the gas laws is the concept of an ideal gas. This is a gas that does obey the laws completely under all circumstances. As the laws break down at the extremes of temperature and pressures, there is no gas that obeys all the laws perfectly. In our practical day-to-day use at room temperature they can be assumed to do so. This simplifies our consideration of them and this presentation highlights these facts.
