Normal adult lung compliance ranges from 0.1 to 0.4 L/cm H20. Compliance is measured under static conditions; that is, under conditions of no flow, in order to eliminate the factors of resistance from the equation.

The mechanics of breathing follow Boyle’s Law which states that pressure and volume have an inverse relationship. The process of inhalation occurs due to an increase in the lung volume (diaphragm contraction and chest wall expansion) which results in a decrease in lung pressure in comparison to the atmosphere; thus, air rushes … cynical beauty
