PY - 2014 T2 - Anesthesiology Core Review: Part One Basic Exam AB - According to Henry’s law, gas solubility describes the tendency of a gas to equilibrate with a solution. When a gas comes into contact with a solution, the gas molecules will move into and dissolve in the liquid. Some of the gas molecules will then move back from the liquid phase to the gas phase. At equilibrium, the number of gas molecules moving from the gas phase to the liquid phase will equal the number of molecules moving from the liquid phase to the gas phase. For example, equilibrium exists when arterial blood with a Pao2 of 100 mm Hg contacts an alveolar gas mixture also with PO2 of 100 mm Hg (Figure 9-1). There is no net gain or loss of O2 between the two phases. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/18 UR - accessanesthesiology.mhmedical.com/content.aspx?aid=1102565937 ER -
