The operational verification procedure (OVP) involves checking the ventilator circuit for leaks. Ventilator settings that could be used to perform this procedure include which of the following?

• A. VT = 500 mL, Flow rate = 20 L/min, High pressure limit = maximum, Inspiratory pause = 2 seconds
• B. VT = 250 mL, Flow rate = 40 L/min, High pressure limit = maximum, Inspiratory pause = 2 seconds
• C. VT = 750 mL, Flow rate = 5 L/min, High pressure limit = 10 cm H2O, Inspiratory pause = 1 second
• D. VT = 100 mL, Flow rate = 100 L/min, High pressure limit = maximum, Inspiratory pause = 3 seconds

Answer: (A)
