Atelectotrauma - Wikipedia
Atelectotrauma, atelectrauma, cyclic atelectasis or repeated alveolar collapse and expansion (RACE) are medical terms for the damage caused to the lung by mechanical ventilation under certain conditions.
Volutrauma and atelectrauma: which is worse? - Critical Care
2018年10月25日 · Therefore, the model of ‘high-volume’ volutrauma at ZEEP is, in reality, a mixture of volutrauma (high tidal volume) and atelectrauma (dependent atelectasis). Advancing damage leads to reduced aerated lung capacity, functionally increased …
Volutrauma and atelectrauma: which is worse? - PMC
The concept of atelectrauma quickly gained general consensus and thereafter strongly influenced the practice of mechanical ventilation. Volutrauma and atelectrauma: the physical basis. Repeated application of an “excess tidal energy load” to the lung parenchyma is …
Atelectrauma or volutrauma: the dilemma - PMC
Atelectrauma, which should be greater at PEEP around 7 cmH 2 O, leads the same outcome of volutrauma, which should be greater at PEEP around 15 cmH 2 O, as shown by the three randomized large trials on PEEP (21-23).
Ventilator Complications - StatPearls - NCBI Bookshelf
2022年9月26日 · Atelectrauma is caused by high-shear forces that open and close recruitable atelectatic lung units. Shear stress and its resultant mechanical damage develop at the interface of air boluses and collapsed recruited airways.
Ventilator-Induced Lung Injury (VILI) - StatPearls - NCBI Bookshelf
2023年4月27日 · The most important measure to prevent ventilator-induced lung injury is to select appropriate ventilatory settings that prevent overdistension of alveoli, causing volutrauma and biotrauma, and atelectrauma.
Ventilator-Induced Lung Injury | New England Journal of Medicine
2013年11月28日 · When ventilation occurs at low lung volumes, lung injury can be caused by the opening and closing of lung units (atelectrauma) as well as by other mechanisms.
Atelectrauma Versus Volutrauma: A Tale of Two Time-Constants
2020年12月16日 · Elucidate how the degree of ventilator-induced lung injury due to atelectrauma that is produced in the injured lung during mechanical ventilation is determined by both the timing and magnitude of the airway pressure profile.
Later studies demonstrated less epithelial injury in lungs ventilated with higher PEEP levels compared with zero end-expiratory pressure.12 PEEP helped reverse atelectasis, thus mitigating injury due to repetitive opening and closing of terminal units, …
Volutrauma and atelectrauma: the physical basis Repeated application of an “excess tidal energy load” to the lung parenchyma is required to induce lung damage.
