In mechanical ventilation, what is the purpose of setting an inspiratory to expiratory (I:E) ratio?

To control the rate of oxygen delivery

To ensure adequate carbon dioxide elimination

To determine the duration of inspiratory versus expiratory phases

To adjust the humidity level of inhaled air

What is the main purpose of using non-invasive ventilation (NIV)?

#10

How does lung recruitment maneuver help in mechanical ventilation?

By decreasing tidal volume

By reducing respiratory rate

By opening collapsed alveoli

By increasing carbon dioxide removal

#11

What is the primary advantage of using a volume-controlled ventilation mode?

It guarantees a set volume delivery regardless of changes in lung compliance.

It allows the patient complete control over the respiratory rate.

It decreases the risk of barotrauma by limiting peak airway pressures.

It improves oxygenation by increasing mean airway pressures.

#12

What complication is associated with high levels of PEEP in mechanical ventilation?

Increased risk of pneumothorax

Decreased cardiac output

Reduced renal perfusion

All of the above

#13

Which of the following best describes the mechanism of High-Frequency Oscillatory Ventilation (HFOV)?

Delivering small tidal volumes at a high frequency to reduce lung injury

Allowing longer expiratory times to prevent air trapping

Providing continuous positive airway pressure to improve oxygenation

Increasing inspiratory pressure to open collapsed alveoli

#14

How does prone positioning benefit patients with severe ARDS?

By improving secretion clearance

By reducing ventilator-associated pneumonia

By improving ventilation-perfusion matching

By increasing tidal volume
