elastic recoil

recoil

 [re-koyl´]
1. to pull back quickly, such as towards a resting position upon removal of a strong opposing force.
2. (re´koil) a pulling back quickly.
elastic recoil the ability of a stretched elastic object or organ, such as the lung or bladder, to return to its resting position. See also elastance.

elastic recoil

[rē′koil]
the difference between intrapleural pressure and alveolar pressure at a given lung volume under static conditions.

elastic recoil

The inherent resistance of a tissue to changes in shape, and the tendency of tissue to revert to its original shape once deformed. A sensitive indicator of elastic recoil (ER) is the coefficient of retraction—the ratio of the maximal static recoil pressure to total lung capacity. ER is the effective pressure driving maximal expiratory airflow, and is increased after lung-reduction surgery for severe emphysema. The ER of lungs is directed centripetally and the lungs have a tendency to deflate, while the ER of the chest wall is directed centrifugally, favouring an increase in lung volume; the sum of the opposing ER of the lungs and the chest wall generates a subatmospheric pressure of -5 cm H2O.

Physiology The inherent resistance of a tissue to changes in shape, and the tendency of the tissue to revert to its original shape once deformed; a sensitive indicator of ER is the coefficient of retraction; ER is the effective pressure driving maximal expiratory air flow, and is ↑ after lung-reduction surgery for severe emphysema. See Coefficient of retraction, Elastance, Lung-reduction surgery. Cf Compliance.
