The observation of both animal and humans has revealed that mechanical ventilation can cause severe lung injury if over-distention occurs (Roupie et al., 1995). To make the matter even worse, the very patients that need mechanical ventilation the most, patients with the acute respiratory distress syndrome for example, are especially susceptible to over-distention and therefore, lung injury (Stewart et al., 1998). The main reason that patients with acute respiratory distress syndrome or respiratory distress syndrome are in higher risk of lung injury is due to over-distention, caused by reduced numbers of alveoli as result of fluid buildup, consolidation, and atelectasis (Roupie et al., 1995).
Another group of patients which require challenging ventilation strategies are the preterm infants. The lungs of preterm infants have undeveloped distal airway structures, with a thick air/blood barrier and a small surface area for gas-exchange (Wallace et al., 2009). They are most likely to be surfactant deficient due to under-developed epithelial cells which lack the type II alveolar cells (Wallace et al., 2009). As a result, preterm infants often require respiratory support in the minutes following birth (Roupie et al., 1995).
Although essential for survival, mechanical ventilation of preterm infants is closely associated with a high risk of developing bronchopulmonary dysplasia (BPD) (Wallace et al., 2009). Bronchopulmonary dysplasia is
