Primer on Mechanical Ventilation

Please note: exam questions are subject to change.

1. Which of the following is NOT an aim of mechanical ventilation? Provide access for medications Relieve respiratory distress Mobilize the chest wall Permit neuromuscular blockade
2. Noninvasive mechanical ventilation interfaces are primarily indicated for which patient population? COPD exacerbation Flail chest trauma Surgical procedures Excessive length of time on mechanical ventilation
3. Which of the following is NOT listed in the VAP Prevention Bundle? Elevate head of the bed to 45 degrees Daily sedation vacations Daily oral care Head down positioning
4. Which of these patient complaints may indicate oxygen toxicity? O2 saturation less than 90% Paradoxical breathing pattern Substernal chest pain Respiratory rate greater than 30 breaths/minute
5. Which of the following is NOT true about mandatory minute ventilation? Alters inspiratory time and peak flow Only parameter controlled by the ventilator If spontaneous breathing does not meet that minute ventilation, the ventilator with provide mechanical breaths to make up the difference. Primarily used in weaning
6. _________ is the delivery of adequate air volume to the lungs by moving air in and out. Ventilation Oxygenation Negative inspiratory force Tidal volume
7. After being intubated for ______, and extubation seems unlikely, a tracheostomy will be considered. 2 weeks 20 hours 1 week 100 hours
8. What is one of the benefits of using pressure-regulated volume control (PRVC) over assist control (AC) mode of ventilation? Maximum oxygen saturation Lower respiratory rate required Lower peak inspiratory pressure Delivers predetermined tidal volume
9. Which ventilator mode is best described as "allows patients to spontaneously breathe though a separate circuit between ventilator provided breaths"? Noninvasive ventilation Pressure Support Ventilation Assist Control SIMV
10. To avoid tracheal damage, what cuff inflation pressure is considered maximal? 5 mmHg 10 mmHg 15 mmHg 20 mmHg
