Fig 1. Schematic representation of the dual-lumen ET-tube used. Note that the
distal end of the secondary lumen is located just at the tip of the main lumen of
the ET-tube. The internal diameter (ID) and the internal cross-sectional area
(a) of the main and secondary lumens are given. The resistance of a size 2.0-
mm ID dual-lumen ET-tube, measured at two different ventilator settings (136
6 3.9 and 132 6 1.1 cm H2O/L/second) were similar to those of a single-lumen
ET-tube of the same size (138 6 2.5 and 148 6 1.6 cm H2O/L/second).
Resistance was measured (PeDs, MAS-PTI, Hatboro, PA) using a lung model
(compliance 5 1.0 mL/cm H2O), and a ventilator (Bourns BP-200, Riverside,
CA) at a rate of 30 cycles/minute at two different settings (PIP/PEEP 5 12/2
and 25/5 cm H2O, and peak inspiratory flow 5 1.0 and 3.5 L/minute).
Tube designed whith secondary lumen for the administration of Surfactant.
