volutrauma

volutrauma

 [vol´u-traw″mah]
damage to the lung caused by overdistention by a mechanical ventilator set for an excessively high tidal volume; it results in a syndrome similar to adult respiratory distress syndrome.

volutrauma

[vol′u-traw′mah]
damage to the lung caused by overdistension by a mechanical ventilator set for an excessively high tidal volume. It results in a syndrome similar to adult respiratory distress syndrome.

air leak syndrome

A condition characterised by alveolar or airway rupture into the pulmonary interstitium, typically accompanied by escape of air into regional tissues, including the pleura, mediastinum, subcutaneous tissues or abdominal cavity; it is more common in children.

Aetiology
Overdistention of lungs, uneven ventilation, chemical injury, trauma, Valsalva manoeuvre, idiopathic (spontaneous).

Predisposing factors
Respiratory distress syndrome, immaturity of lungs, positive pressure ventilation, foetal distress/asphyxia, botched intubation, atelectasis, resuscitation, tracheal suctioning, pneumonia including aspiration pneumonia.

volutrauma

(vŏl′ū-traw″mă) [L. volumen, scroll, something rolled, + Gr. trauma, wound]
A lung injury caused by excessively high tidal volumes during the use of mechanical ventilation.

Benefits from PCV (lower work of breathing and patient comfort)usually comes from decelerating flow waveform and benefits from VCV are related to reducing volutrauma.
Comparison of pressure vs. volume controlled ventilation on oxygenation parameters of obese patients undergoing laparoscopic cholecystectomy
The majority of otherwise healthy patients are capable to successfully compensate for these changes, but obese patients and those with chronic respiratory diseases are susceptible to development of numerous complications such as intraoperative hypoxia, barotrauma and volutrauma during laparoscopic procedures (1).

Volutrauma may develop from increased airway pressure with alveolar over-distension, or from shear forces applied during opening and closing of small airways.
Acute respiratory distress syndrome
Os efeitos negativos da ventilacao com altos volumes e pressao foram demonstrados em animais e o conceito de repouso pulmonar foi progressivamente aceito (2) em consequencia a tais resultados e nos anos 90, adotou-se a utilizacao de baixos volumes correntes (6 a 7 ml/kg) para evitar danos provocados pela ventilacao mecanica, como o volutrauma.

Differences in the performance of VHI, such as inspiratory flow rates, plateau time, peak pressures and volumes delivered, raise concerns about the efficacy of treatment and patient safety with regards to barotrauma and volutrauma.

Ventilator strategies include tidal volumes of 10 to 12ml/kg for limiting volutrauma, respiratory rates up to 14 breaths/minute for maintaining normocapnia, and positive end-expiratory pressure of 5 to 10cm H2O for improving oxygenation.
