, atelectrauma (at″ĕl-ek″tŏ-tro′mă) (-ek″tro′mă) [ atelectasis + trauma]
Injury to the lung caused by shearing forces as alveoli that are next to each other collapse and re-expand during mechanical ventilation. The condition may be prevented by applying enough positive end-expiratory pressure to limit alveolar collapse at end expiration.

PEEP recruits collapsed alveoli, improving oxygenation and lung compliance, and reduces cyclic atelectasis, decreasing atelectrauma and biotrauma.
Recruitment maneuvers can increase the aerated lung mass and prevent atelectrauma caused by repeated opening and closing of terminal respiratory units (71).
T] accurately to avoid underventilation or overdistension, deliver accurate pressures to avoid barotrauma, and has the ability to optimise PEEP to avoid atelectrauma and maintain the set Fi[O.
VILI is a complex collection of lung deconstuctive elements that manifests itself in a number of forms including but is not limited to the following categories of ventilator induced lung injury; Volutrama, Barotrauma, Biotrauma, RACE and Atelectrauma.
The deleterious effects from loss of positive end expiratory pressure (PEEP) on lung function and mechanics that occurs when patients are disconnected from the ventilator include a reduction in functional residual capacity, possible atelectrauma and a decrease in oxygenation (Amato et al 1998, Barker and Adams 2002, McCann et al 2001, Savian et al 2005).
If intra-airway propagation is a genuine hazard, timing of PEEP application and positioning may be of under-recognized importance for reasons unrelated to atelectrauma.
HFV helps to reduce barotrauma with low pressures, biotrauma and atelectrauma.
This reduces the need for high pressures and high FIO2, which will reduce barotrauma, biotrauma, atelectrauma and possibly even volutrauma.
