<unk>  (Derived from the German words for pendulum and air.) refers to the movement of gas between two regions of the lung, usually between regions of differing compliance or airway resistance.<unk>  is an important physiological concept to take into account during mechanical ventilation, particularly in patients with an open thorax, severe bronchospasm (e.g. asthma or COPD), or with heterogeneous lung compliance (e.g. ARDS). It was first published as a physiological concept in 1956. Illustration of the pressure-time waveform during an inspiratory hold. During the inspiratory hold, the decay in pressure towards the true plateau pressure is due to<unk> , as well as the relaxation of elastic chest wall / lung tissue.
