Patient discomfort from rapid gas flow during pressure-targeted ventilation may be alleviated by which of the following adjustments to the ventilator?
 
  a. Decreasing expira-tory time c. Increasing inspira-tory time
  b. Decreasing total cycle time d. Increasing inspira-tory rise time

Question 2

The statement The breaths are pressure-limited, but the pressure limit can be adjusted between breaths to achieve a preset tidal volume describes which of the following modes of ventilation?
 
  a. Dual mode c. Adaptive mode
  b. Servo mode d. Knowledge-based mode

Answer to Question 1

ANS: D
Adding or increasing inspiratory rise time changes the rate of gas delivery at the very beginning of inspiration. This tapers the rise of pressure and flow delivery until they reach their maximum value.

Answer to Question 2

ANS: C
This statement describes an adaptive mode because the ventilator has one set-point and automat-ically adjusts the set-point to achieve another set-point as the patient's condition changes.
