Examines correlation between mechanical power and lung viscoelasticity, suggesting potential clinical implications.
BACKGROUND: Lung protective ventilation strategy, aiming to decrease ventilation-induced lung injury, is based on 2 major principles: (1) ventilation at a narrow range of volume, with low plateau and driving pressures, while (2) keeping the lung open, to avoid tidal alveolar recruitment/de-recruitment. Mechanical power (MP) was developed as a single value describing energy transfer to the lungs. Energy transfer to the lung parenchyma during ventilation is associated with the viscoelastic properties of the lung. This study aimed to describe the correlation between MP and the viscoelastic properties of the lung. METHODS: ) and MP were calculated for each inspiratory hold. Those measurements were compared. MP was correlated with the viscoelastic properties of the lung. RESULTS: and MP. CONCLUSIONS: . The clinical implication of this finding has yet to be defined.
