Text: Indexes of respiratory effort decreased significantly during the two modes of NIMV compared with spontaneous breathing, with PTPdi/min decreasing from 497. 8 + / - 115. 4 cm H2O x sec x min (-1) during spontaneous breathing to 127. 8 + / - 98. 3 cm H2O x sec x min (-1) and 184. 3 + / - 79. 8 cm H2O x sec x min (-1), during AC/VT and pressure support, respectively (p <. 0001), and the work of breathing decreasing from 1. 83 + / - 0. 12 J. L-1 during spontaneous breathing to 0. 48 + / - 0. 32 J. L-1 and 0. 75 + / - 0. 30 J. L-1, during AC/VT and pressure support, respectively (p <. 0001).
