Table 2. Respiratory Mechanics in Nonresponders and Responders on Zero End-expiratory Pressure

Data are mean ± SD.

*P < 0.01, Wilcoxon for unpaired data Nonresponders vs.  Responders.

LIP^L= lower inflection point on the static pressure-volume curve of the lung; UIP^L= upper inflection point on the static pressure-volume curve of the lung; Est,^L= static elastance of the lung; Est,^W= static elastance of the chest wall.
