Table 1 The mechanism of action for surfactant in ARDS

From: Effect of surfactant administration on outcomes of adult patients in acute respiratory distress syndrome: a meta-analysis of randomized controlled trials

The mechanism of action for surfactant
 The capacity to maintain lower alveolar tension and stability of alveolar volume
 Promotion of gas exchange and distribution
 Anti-action of edema in alveoli and interstitium
 Modulation of systemic inflammatory reactions in ARDS
 Reduction of local mechanical forces in ARDS
