VENTILATION
1. All of the following patients are intubated and receiving

mechanical ventila-tion. Which of

them is most likely to require slow liberation from mechanical

ventilation?: A patient with chest contusions from a motor vehicle crash

2. What ends inspiration in pressure support ventilation?: Flow

3. At what pressure is pressure support not high enough to

contribute signifi-cantly to ventilatory

support but is sufficient to overcome the work imposed by the

ventilator system?: 5 cm H2O

4. Which mode of ventilation delivers the exact amount of pressure

required to overcome the

resistive load imposed by the ET tube for the flow measured at the

time?: Au-tomatic tube compensation

5. The mode of ventilation that maintains a minimum VE by

increasing or decreasing the amount

of support (VT or respiratory rate) given to the patient is .: -

mandatory minute ventilation

6. Which of the following is considered a closed-loop mode used for

weaning from mechanical

ventilation?: Adaptive support ventilation

7. A postoperative patient, still under anesthesia, is being

ventilated with VC-CMV with

automode. After 2 hours, the patient is waking up and beginning

to breathe spontaneously.

The ventilator will respond by .: switching to the volume support

mode

8. The ACCP/SCCM/AARC task force recommends that a search for all

possible causes that

may be contributing to ventilator dependence be undertaken in

patients who
