5 Written Questions

1. Assist mode, pt makes a small effort, vent will deliver full Vt....Not good for pt hyperventilating,because pt can initiate breath ABOVE that set f...NOT A SPONTANEOUS MODE.
2. may increase WOB too much, making it very difficult for pt to breath on own.
3. Mandatory, Spontaneous and ASSISTED
4. Pressure Constant, Limits pressure to the lungs, prevents overdistention SET Pressure, I Time, f and FiO2
5. Spontaneous Breathing Pt...Positive Pressure..Increase FRC and Oxygenation

5 Matching Questions

1. Assisted breaths
2. Advantages of NPPV
3. PVS Modes
4. Disadvantages of NPPV
5. Modes

1. a SIMV, PSV..
2. b Types of breaths...Mandatory(machine), Spontaneous, and Assisted.
3. c all or part of the breath is generated by the vent.
4. d Gastic distention, skiin pressure lesions, facial pain, dry nose, eye irritation, poor sleep and mask leaks.
5. e avoids complications associated with artificial airways, reduces heavy sedation, preserves airway defense(cough, Speech, Swallowing), Reduces need for invasive monitoring.

   4. Volume Ventilation VCV

5 True/False Questions

1. SIMV Advantages → Enhanced pt-vent synchrony, pt assumes some WOB, can be used to wean, set rate and slowy decrease rate...REDUCES HYPERVENTILATION seen with resp alkalosis..

   True        False

2. Spontaneous breaths → vent controls timing or Vt, or both.

   True        False

3. Non-Invasive → artificial airway..Endo tube, Trach.

   True        False

4. Disadvantage of VCV → Vt delivery varies with lung characteristic...LESS control over PaCO2..

   True        False

5. Invasive → artificial airway..Endo tube, Trach.

   True        False
