Synchronized Intermittent Mandatory Ventilation (SIMV)
Volume Control Ventilation (VCV)
#7
In mechanical ventilation, PEEP stands for:
Peak Expiratory Exhalation Pressure
Positive End-Expiratory Pressure

Tidal volume
Peak inspiratory pressure
Inspiratory time
Respiratory rate
#11
Which of the following ventilator parameters represents the amount of air delivered with each breath?
Respiratory Rate (RR)
Tidal Volume (Vt)
FiO2
PEEP
#12
Which ventilator mode is commonly used in patients with neuromuscular diseases to support spontaneous breathing?
Pressure Control Ventilation (PCV)
Continuous Positive Airway Pressure (CPAP)
Volume Assist Control (VAC)
Airway Pressure Release Ventilation (APRV)
#13
Which of the following is a potential complication of barotrauma in mechanically ventilated patients?
Hypovolemia

Hyperglycemia
#14
Which ventilator mode allows the patient to breathe spontaneously with a constant positive pressure applied at the airway throughout the respiratory cycle?
Volume-Controlled Ventilation (VCV)
Pressure-Controlled Ventilation (PCV)
Continuous Positive Airway Pressure (CPAP)
Assist-Control Ventilation (ACV)
#15
What is the primary advantage of pressure-controlled ventilation (PCV) over volume-controlled ventilation (VCV)?
PCV provides better oxygenation.
PCV allows for better control of tidal volume.
PCV reduces the risk of barotrauma.
PCV synchronizes better with patient's spontaneous breaths.
