Lung-protective ventilation has proved to lessen ventilation-induced lung injury and to reduce mortality, while longer prone duration helps to increase lung recruitment and enhances gas exchange [ 23, 24].
These results are in keeping with experimental studies that evidenced that prone ventilation lessened the histological injury associated with high peak pressure ventilation in a dog model of oleic-acid lung injury [81].

The addition of a third chamber, between the front and the back bedroom, to serve as dressing room and washroom, was the first step backward; it lessened the possibility of through ventilation.
Specifically, insufficient pressure can lead to air leakage, which lessens the effect of mechanical ventilation and results in the leakage of inhalation anesthetics [ 1], while excessive pressure can cause serious injury and affect blood flow to the tracheal mucosa, resulting in tracheal stenosis, fistula, or tracheal rupture [ 2, 3].
Over the years, the incidence of right ventricular dysfunction (RVD) has declined as improvements in mechanical ventilation have been adopted and lessened the intrathoracic airway pressure in patients with ARDS [17],[19], but RVD is variably defined and diagnosed among studies which makes comparison difficult.

The clinical relevance of experimental ventilator-induced lung injury recently received a resounding illustration from the ARDS Network Trial, which showed a 22% reduction in mortality in patients with ARDS when lung mechanical stress was lessened by tidal volume reduction during mechanical ventilation.
The use of neuromuscular-blocking agents (e.g. vecuronium, atracurium, cis-atracurium, pancuronium) lessens the patient ventilator asynchronism (thus permitting more effective ventilation), lowers the risk for barotrauma, reduces oxygen consumption and dioxide production, and reduces lactate accumulation.
In this way, atrophy of muscles, particularly intra-costal muscles and diaphragm, could be lessened in IUC patients that are supported by artificial ventilation.
In contrast to controls EF, walking distance and exercise capacity increased, while parameters of respiratory instability improved remarkably: daytime hyperventilation was reduced, sensitivity of central CO2 receptors decreased, while exercise ventilation got more efficient and EOV at rest and during exercise lessened.
