Answer to Question 1

ANS: D
The flow setting on a mechanical ventilator determines how fast the inspired gas will be deliv-ered to the patient. During continuous mandatory ventilation (CMV), high flows shorten inspira-tory time (TI) and may result in higher peak pressures and poor gas distribution.

Answer to Question 2

ANS: D
In situations where plateau pressure (PPlateau) is critical, changing to a descending ramp in order to reduce peak pressures may increase the mean airway pressure.
