Development of the Partial Pressure of a Gas in Solution

Henry's law explains the behavior of gases in solutions and can be extended to body tissues. In many ways, inhalation anesthetic agents appear to be inert gases that interact with tissues and liquids physically rather than chemically. Therefore, laws governing the physical association of gases and liquids are of paramount importance to an understanding of the pharmacokinetics of these drugs. Henry's law describes the regulation of a gas concentration in a liquid when the association of these two phases is through physical interaction alone. The law states that at equilibrium, the concentration of gas physically dissolved in a liquid is directly proportional to the partial pressure (or tension) of the agent and its affinity for the molecules of the liquids (or its solubility in the liquid).

For a clear understanding of Henry's law, it is important to consider each of its component parts.

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
