Impact of Recruitment on Static and Dynamic Lung Strain in Acute Respiratory Distress Syndrome

摘要

Background: Lung strain, defined as the ratio between end-inspiratory volume and functional residual capacity, is a marker of the mechanical load during ventilation. However, changes in lung volumes in response to pressures may occur in injured lungs and modify strain values. The objective of this study was to clarify the role of recruitment in strain measurements.
