Based on the work done by Ranieri and associates, how did mechanically ventilated patients compensate for induced hypercapnia caused by increased mechanical Vds during PSV and PAV?
 
  A. Patients using PSV increased their minute ventilation by increasing their Vts.
  B. Patients receiving PSV and PAV increased their minute ventilation by increasing their respiratory rates.
  C. Patients being given PAV increased their minute ventilation by increasing both their Vts and respiratory rates.
  D. Patients ventilated with PAV increased their minute ventilation by increasing their Vts.
