FFICM Respiratory Management and Mechanical Ventilation

Question 1

According to the ARDSNet protocol, what tidal volume is recommended for lung-protective ventilation in ARDS?

Accepted Answer

6 ml/kg predicted body weight

Answer

10 ml/kg actual body weight

Answer

8 ml/kg ideal body weight

Answer

12 ml/kg predicted body weight

Question 2

What is the target plateau pressure in lung-protective ventilation to minimize ventilator-induced lung injury?

Accepted Answer

≤30 cmH2O

Answer

≤40 cmH2O

Answer

≤20 cmH2O

Answer

≤50 cmH2O

Question 3

In pressure-controlled ventilation (PCV), which parameter is directly set by the clinician?

Accepted Answer

Inspiratory pressure above PEEP

Answer

Tidal volume delivered

Answer

Peak expiratory flow rate

Answer

Mean airway pressure

Question 4

What is the primary physiological purpose of applying PEEP in mechanically ventilated patients with ARDS?

Accepted Answer

Prevent alveolar derecruitment and improve oxygenation

Answer

Reduce the patient's inspiratory effort

Answer

Decrease inspiratory time and improve CO2 clearance

Answer

Lower peak airway pressures by reducing flow

Question 5

Which ventilator mode delivers mandatory breaths at a minimum set rate while allowing the patient to trigger additional spontaneous breaths?

Accepted Answer

Synchronized Intermittent Mandatory Ventilation (SIMV)

Answer

Continuous Positive Airway Pressure (CPAP)

Answer

Assist-Control Ventilation (ACV)

Answer

Airway Pressure Release Ventilation (APRV)

Question 6

Patient Self-Inflicted Lung Injury (P-SILI) in spontaneously breathing patients primarily results from:

Accepted Answer

Excessive respiratory effort generating injurious transpulmonary pressure swings

Answer

Positive pressure delivered by the ventilator during inspiration

Answer

Barotrauma from high set PEEP levels

Answer

Secretion retention causing focal atelectasis

Question 7

In volume-controlled ventilation (VCV), which parameter varies in response to changes in respiratory system compliance?

Accepted Answer

Peak airway pressure

Answer

Delivered tidal volume

Answer

Set respiratory rate

Answer

Inspiratory flow waveform
