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.

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.

(4) Prolonged intubation and mechanical ventilation may be associated with bronchopulmonary dysplasia (BPD) because of barotrauma, volutrauma, and oxygen toxicity.

Comparing the Efficacy of Nasal Continuous Positive Airway Pressure and Nasal Intermittent Positive Pressure Ventilation in Early Management of Respiratory Distress Syndrome in Preterm Infants

Results: The pathogenesis of VILI was defined gradually, from traditional pathological mechanisms (barotrauma, volutrauma, and atelectrauma) to biotrauma.

Molecular Mechanisms of Ventilator-Induced Lung Injury

Ventilator management is essential to prevent further pulmonary insult from high pressure volumes (volutrauma) and peak airway pressures (barotrauma) (Arbour, 2017; Carlucci et al., 2014).

Acute Respiratory Distress Syndrome

Other complications such as volutrauma, and high FI[O.sub.2] may stimulate chemokines and cytokine inflammatory mechanisms, inducing injury to the epithelial cells.

Updates on the Status of Vitamin D as a Risk Factor for Respiratory Distress Syndrome

The patient should remain during the treatment (to allow recovery of lung function) with "rest" settings (Fi[O.sub.2] 25-30%, peak inspiratory pressure (PIP) 20-25 cm [H.sub.2]O; positive end expiratory pressure (PEEP) 45 cm [H.sub.2]O; inspiratory time (Ti) 0.5-1.0 seconds; frequency (F) 20-25 breaths per minute) or even in continuous positive airway pressure (CPAP) with a high PEEP (10-12 cm [H.sub.2]O) in order to maintain functional residual capacity (FRC) without causing lung injury (volutrauma, barotrauma, or atelectrauma).

Respiratory Care for the Ventilated Neonate

These factors (such as inflammation, hyperoxia, barotraumas, and volutrauma) act synergistically to cause damage to the immature lung.

Treatment of Hyperoxia-Induced Lung Injury with Lung Mesenchymal Stem Cells in Mice

Average tidal volume in the NIV group was 9-2 mL k[g.sup.-1], thought to have contributed to greater volutrauma and thereby heightened mortality, but tidal volume was measured in neither the standard oxygen nor HFNT group.

Noninvasive Ventilation for Acute Hypoxemic Respiratory Failure/ARDS--is There a Role?

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.23 PCV has no advantage compared to PCV if patient does not have spontaneous breathing especially if VCV uses decelerating flow.

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).

EFFECTS OF PRESSURE-CONTROLLED AND VOLUME-CONTROLLED VENTILATION ON HEMODYNAMIC AND RESPIRATORY PARAMETERS IN PATIENTS DURING LAPAROSCOPIC CHOLECYSTECTOMY

This was done to minimize the risk of either barotrauma or volutrauma; the mother had been educated by the child's pulmonologist on this specific ventilator and thus had training in its operation.

In-Flight Hypoxemia in a Tracheostomy-Dependent Infant

Sustained mechanical distension of the lungs due to hyperinflation, contributes to volutrauma, barotrauma, and biotrauma, which may cause intensive stress leading to direct cell injury.

Lung-Protective Ventilation Strategies for Relief from Ventilator-Associated Lung Injury in Patients Undergoing Craniotomy: A Bicenter Randomized, Parallel, and Controlled Trial

Lung damage is often exacerbated by volutrauma, hyperoxia and mechanical ventilation.
