Operating Modes of Mechanical Ventilation 117

3. Positive end-expiratory pressure (PEEP) is most commonly used to correct:
A. hypercapnia. C. refractory hypoxemia.
B. mild hypoxemia. D. respiratory acidosis.

4. When PEEP is applied to the airway of a spontaneously breathing patient, it is called:
A. airway pressure release ventilation.
B. continuous positive airway pressure.
C. pressure support ventilation.
D. pressure-controlled ventilation.

5. _______ is a mode in which the ventilator delivers control (mandatory) breaths and allows the patient
to breathe spontaneously between the mandatory breaths.
A. Intermittent mandatory ventilation
B. Continuous positive airway pressure
C. Mandatory minute ventilation
D. Airway pressure release ventilation

6. _______ delivers control (mandatory) breaths to the patient at or near the beginning of a spontaneous
breath, thus avoiding breath stacking.
A. Continuous positive airway pressure
B. Airway pressure release ventilation
C. Intermittent mandatory ventilation
D. Synchronized intermittent mandatory ventilation

7. _______ best describes the mode of ventilation that changes the number of mandatory breaths and pres-
sure support level according to the patient’s breathing pattern.
A. Automatic tube compensation
B. Volume ventilation plus
C. Adaptive support ventilation
D. Volume-assured pressure support

8. _______ is primarily used to reduce the work of breathing imposed by the endotracheal tube and ventila-
tor circuit during spontaneous breathing.

A. Pressure support ventilation
B. Pressure-controlled ventilation
C. Airway pressure release ventilation
D. Continuous positive airway pressure

9. _______ is a mode of ventilation that changes the pressure support level according to the changes in
volume, elastance, airflow resistance, and flow demand.

A. Proportional assist ventilation (proportional pressure support)
B. Pressure support ventilation
C. Volume-assured pressure support
D. Automatic tube compensation
