Mechanical Ventilation Quiz

What is the purpose of mechanical ventilation?

• To deliver oxygenated air into the lungs

• To remove carbon dioxide from the body

• To assist with breathing in patients who are unable to do so on their own

• All of the above

When is mechanical ventilation indicated?

• When a patient is unable to maintain adequate ventilation

• When a patient has insufficient oxygenation

• When a patient has an acute lung injury

• All of the above

What is the purpose of intubation in mechanical ventilation?

• To protect the patient's airway

• To deliver positive pressure breaths

• To establish a link between the patient and the ventilator

• All of the above

What are the benefits of mechanical ventilation?

• Decreases work of breathing

• Maintains adequate oxygenation

• Helps remove carbon dioxide

• All of the above

What are some common risks and complications of mechanical ventilation?

• Barotrauma

• Ventilator-associated pneumonia

• Oxygen toxicity

• All of the above

What are the primary types of mechanical ventilation?

• Positive pressure

• Negative pressure

• Invasive

• Non-invasive

What is the difference between volume control and pressure control ventilation?

• Volume control delivers a fixed volume, while pressure control delivers a fixed pressure

• Volume control protects the lungs from over inflation, while pressure control regulates minute ventilation

• Volume control is used for partial ventilatory support, while pressure control provides full ventilatory support

• Volume control is indicated for patients with refractory hypoxemia, while pressure control is indicated for patients with acute lung injury

What is the primary advantage of assist control mode?

• It delivers a minimum number of preset mandatory breaths

• It allows the patient to initiate spontaneous breaths

• It provides full ventilatory support

• It protects the lungs from over inflation

What is the purpose of positive end expiratory pressure (PEEP)?

• To prevent alveolar collapse

• To increase lung compliance

• To decrease airway resistance

• To improve oxygenation

What are the primary ventilator settings?

• Mode, tidal volume, frequency rate, fio2

• Flow rate, IE ratio, sensitivity, peep

• Ventilator alarms, volume support, control mode, mandatory minute ventilation

• All of the above
