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.

This PSV augmented tidal breath will be more easily trapped in the area of lung that is super compliant while having no elastic recoil.
in this light, it is interesting to note that strong elastic recoil (7) and fast healing processes (16) are also found in amorphous polymers.
Treatment of these lesions can be complicated by challenging anatomy that makes catheter delivery difficult, balloon slippage leading to "geographic miss," elastic recoil and the need to use high pressures to open lesions.
The catheter is designed to enable dilatation of fibrocalcific lesions at lower pressure; reduce "geographic miss" due to slipping of traditional angioplasty balloons; reduce elastic recoil in ostial side branches; and facilitate stent placement and expansion.

Because the device scores the lesion with precise incisions, it may also prevent elastic recoil in these stubborn lesions.
This new aerosol delivery device stores the aerosol that is generated during the patient's exhalation phase in a non-latex elastic reservoir bag, and releases it to the patient on the subsequent breath, with a slight boost from the elastic recoil of the expanded bag, along with the other aerosol that the nebulizer is generating.
The RePneu LVRC System is a minimally invasive device intended to improve lung function in emphysema patients by brochoscopically implanting Nitinol coils into the lungs to compress damaged tissue (lung volume reduction) and restore elastic recoil to the healthier lung tissue.
