EDS = effective dead space of the face mask; Pj = jacket pressure.
-
↵1-150 EDS was measured in each infant with a water volumeter.10
-
↵1-151 This Pj generated the highest forced vital capacity and was used when measuring the residual volume (RV) by nitrogenwashout.
-
↵1-152 A Pj 10 cm H2O higher was used once when measuring RV and did not result in a lower RV.
