CHAPTER 27. Mechanics of Ventilation

Walter F. Boron

The field of pulmonary mechanics—the physics of the lungs, airways, and chest wall—deals with how the body moves air in and out of the lungs, producing a change in lung volume (VL). When we examine these mechanical properties while no air is flowing, we are studying static properties. The situation becomes more complicated under dynamic conditions, when the lungs are changing volume and air is flowing either in or out.
