MECHANICAL VENTILATION EXAM 2 UPDATED
ACTUAL QUESTIONS AND CORRECT ANSWERS
Question 1.
Which types of ventilation is alveolar expansion during inspiration due to a decrease in pleural
pressure?
ANSWER
NPV & spontaneous ventilation
Question 2.
Describe in detail negative pressure ventilation (NPV)
ANSWER
decrease Ppl (pleural pressure) during inspiration by exposing the chest to subatmospheric
pressure. "box surrounding the lungs/enclosed form"
Question 3.
In which of the following types of ventilation is alveolar expansion during inspiration due to an
increase in alveolar pressure?
ANSWER
Positive-pressure ventilation
Question 4.
On what does volume delivered depend during pressure-targeted modes of ventilatory support?
ANSWER
I. Set pressure limit II. Patient lung mechanics III. Patient effort
Question 5.
For patients with respiratory insufficiency, pressure-supported ventilation (PSV) has all of the
following advantages over spontaneous breathing except:
ANSWER
, Increased muscle activity
Question 6.
Which of the following statements are TRUE about negative-pressure ventilation (NPV)?
ANSWER
I. NPV is similar to spontaneous breathing. II. Airway (mouth) pressure during NPV is zero. III.
Expiration during NPV is by passive recoil. IV.NPV decreases pressure at the body surface.
Question 7.
Which of the following variables determine the level of support achieved with adaptive support
ventilation?
ANSWER
I. Patient effort III. Resistance of the endotracheal tube
Question 8.
Inspection of the airway pressure waveform of a patient receiving volume-controlled continuous
mandatory ventilation assist-control with constant flow reveals a large dip or drop in pressure at the
beginning of inspiration. Which of the following problems is most likely?
ANSWER
The trigger setting is improper.
Question 9.
Which of the following parameters are set when volume-supported ventilation (VSV) is used?
ANSWER
I. Tidal volume II. Maximum peak pressure
III. Positive end-expiratory pressure (PEEP) IV. Flow
