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

may be contributing to ventilator dependence be undertaken in
