Back to Basics: Common Modes of Mechanical Ventilation and Applications

Please note: exam questions are subject to change.

1. Identify the 3 common modes of ventilation: Assist Control SIMV Pressure Support All of the above
2. What will happen on volume control ventilation if the patient has decreased compliance? Volume will vary to deliver the set pressure Pressure will increase to deliver the set volume Pressure will decrease to deliver the set volume Volume will vary to deliver the variable pressure
3. What is plateau pressure? Distinguishes airway resistance and lung compliance problems Pressure measurement in the lung with flow present Pressure measurement in the lung without flow present Answers A & C
4. What is I:E ratio? Determined by sensitivity when using APRV mode of ventilation Determined by the I-time when using pressure controlled ventilation Determined by the flow when using volume controlled ventilation Both B and C
5. What is impending respiratory failure? Progressive acidosis with pH less than 7.30 Progressive hypoventilation wiht PaCO2 greater than 50 mmHg Spontaneous frequency greater than 30 breaths per minute All of the above
