2018年11月11日 · Volutrauma versus Barotrauma So which is the mechanism of lung injury, volutrauma or barotrauma? They are – in essence – the same thing but only when one considers tidal volume in relation to FRC [i.e. strain] and airway pressure in …

The distinction between volutrauma and barotrauma then vanishes where at the cellular level, stretching the lung beyond its capacity ruptures alveolar cell membranes [40], and the resulting cell death induces inflammation.

A statement in a contemporary textbook1 on mechanical ventilation declared, “It is clear that microvascular lung injury and pulmonary edema during mechanical ventilation are the consequences, not of ‘barotrauma,’ but, rather, of Volutrauma.'”

2023年4月27日 · Complications of ventilatory induced lung injury include pulmonary edema, barotrauma, worsening hypoxemia resulting in prolongation of mechanical ventilation. Though higher tidal volumes are proved to increase mortality, multiorgan failure resulting from biotrauma is a major contributor.

2018年10月25日 · Conceptually, both atelectrauma and barotrauma recognize excessive mechanical energy as causal to repeated nonphysiological strain. Volutrauma is usually interpreted to imply lung overdistension.

Clinically significant VILI occurs from volutrauma, barotrauma, atelectrauma, biotrauma, and shear strain. Differences in regional mechanics play an increasingly recognized role in VILI pathogenesis. Several interventions targeting these mechanisms are …

The two terms—barotrauma and volutrauma—reflect the two sides of the same phenomenon: the lung injury due to a large distending volume and/or to a high airway pressure (10-19).

In summary, while both barotrauma and volutrauma involve lung injuries, they differ in their causes and manifestations. Barotrauma is associated with sudden changes in pressure, while volutrauma is linked to overdistention of the lung tissue during mechanical ventilation.

2023年3月1日 · Three types of VILI are barotrauma, volutrauma, and biotrauma. In barotrauma, there is an increase in pressure in the alveoli compared to extra-alveolar tissues, which leads to their rupture.

2023年11月20日 · While Barotrauma and Volutrauma differ in their primary causes and affected areas, they do share some similarities: Lung Injury: Both Barotrauma and Volutrauma cause damage to lung tissues, albeit through different mechanisms.
