Which of the following variables determine the level of support achieved with adaptive support ventilation?
 
  1. Patient effort
  2. Elastance
  3. Resistance of the endotracheal tube
  a. 1 and 3 only
  b. 2 only
  c. 1 only
  d. 1, 2, and 3

Question 2

What factor primarily determines the effect of positive-pressure ventilation (PPV) on the cardiac output?
 
  a. Peak airway pressure
  b. Mean pleural pressure
  c. CO2
  d. Expiratory time

Answer to Question 1

ANS: A
Automatic tube compensation is similar to the flow assist of proportional assist ventilation but only considers the resistance of the endotracheal tube.

Answer to Question 2

ANS: B
More specifically, the decrease in left ventricular output corresponded to the increase in pleural pressure that occurred with PPV.
