Postnatal atelectasis refers to an airless state of the pulmonary parenchyma which occurs when tributaries serving it become obstructed and circulating blood absorbs the last vestiges of air. 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
