Questions and Answers

What is the primary function of Positive End-Expiratory Pressure (PEEP) in mechanical ventilation?

To synchronize ventilator breaths with patient's breathing pattern and minimize fatigue.

To increase lung compliance and decrease barotrauma risk.

To increase tidal volume delivered and improve oxygenation.

To maintain open small airways and decrease preload. (correct)

Which ventilation mode uses a constant flow rate to deliver a set tidal volume?

Pressure-Control Ventilation (PCV)

Volume Control (VC) (correct)

Synchronized Intermittent Mandatory Ventilation (SIMV)

Pressure-Support Ventilation (PSV)

What is the primary advantage of Pressure-Control Ventilation (PCV) over Volume Control (VC)?

It delivers a guaranteed tidal volume, minimizing the risk of hypoventilation.

It allows for spontaneous breathing and facilitates weaning from mechanical ventilation.

It reduces inspiratory pressures and minimizes the risk of barotrauma. (correct)

It is synchronized with patient's breathing pattern and minimizes ventilator dyssynchrony.
