Quality control of an automated DLCO system is performed using a 3-L syringe.The syringe is filled to 1.5 L with room air and is then connected to the system.A simulated DLCOsb maneuver is performed with 1.5 L of test gas drawn into the syringe.Acceptable performance of the gas analyzers should produce a DLCO of approximately:
A) 0 ml CO/min/mm Hg
B) 25 ml CO/min/mm Hg
C) 50 ml CO/min/mm Hg
D) 100 ml CO/min/mm Hg

The DLCO (Diffusing Capacity of the Lung for Carbon Monoxide) should be approximately 0 ml CO/min/mm Hg when using a 3-L syringe filled with room air and test gas, as there is no actual diffusion occurring in this setup.
