Which of the following alternatives may increase the FIO₂ capabilities of air-entrainment nebulizers?
I. Add open reservoir to expiratory side of T-tube.
II. Connect together two or more nebulizers.
III. Use a commercial dual-flow system.
IV. Add open reservoir to inspiratory side of T-tube.

Question

Quizplus · Accepted Answer

Adding an open reservoir to the inspiratory side of the T-tube will increase the FIO₂ but adding it to the expiratory side may lead to CO2 retention. Connecting multiple nebulizers and using a commercial dual-flow system can both increase the output and efficiency of the nebulizers. Therefore, the best choice(s) is I, II, and III. Option IV may lead to decreased FIO₂ due to increased dead space.
