Ventilatory ebb and flow is a mechanical function conforming to physical laws. Measurements of volume rate of flow, linear velocity, pressures applied, the stress imposed on tissue, and the forces involved have disclosed a wide range of values, out of keeping with an older notion that breathing is relatively effortless. These define the physical nature of all ventilatory disorders, and the first part of this report deals with their relation to...Bibliography1.
