Role of Elastic Power in Acute Respiratory Distress Syndrome

Mechanical ventilation is essential for managing acute respiratory distress syndrome (ARDS), but it can also cause ventilator-induced lung injury (VILI) due to mechanical forces. VILI results from the interaction between lung structure and mechanical ventilation factors, such as tidal volume, plateau pressure, driving pressure, inspiratory flow, respiratory rate, and PEEP. Intrinsic factors like lung heterogeneity further increase the risk. Elastic power (EP), a key component, is linked to repetitive alveolar stretching and disease progression. Study Objectives: Examine the correlation between elastic power and pulmonary hyperinflation. Compare EP's sensitivity and specificity with other overdistension markers like driving pressure, plateau pressure, upper inflection point, and compliance.
