Relationship between lung compliance and tidal volume selection in acute respiratory distress syndrome.

??Abstract??Ventilation with low tidal volume (Vt)normalized to ideal body weight (IBW) has become a doctrine for the ventilation of patients with ARDS since the end of last century and mortality of ARDS has decreased to some extent.However??it is still highly debatable about how to choose a suitable tidal volume.Recently??with better insights into ARDS’ pathophysiological changes and its respiratory mechanics??especially with the more popular use of EIT??critical ultra sound and lung stress and strain??it is feasible to choose tidal volume individually according to the lung compliance of ARDS patients.
