The therapist is preparing to establish a patient on ILV with two ventilators for the purpose of treating unilateral lung disease and is trying to determine the appropriate Vt to set on each ventilator. If this patient were to receive ventilation of both lungs with one ventilator, he would receive about 6 ml/kg of IBW. How should the therapist set the Vt for this patient?
A. Each lung should receive 6 ml/kg.
B. The diseased lung should receive 3ml/kg, and the normal lung 6 ml/kg.
C. Both lungs should receive 3 ml/kg.
D. The therapist should ventilate each lung with a Vt that does not cause the Pplateau to exceed 30 cm H2O in each lung.

What is the purpose of tracheal gas insufflation?
