Ventilatory support strategies likely to result in auto-positive end expiratory pressure (PEEP) in-clude which of the following?
 
  1. Continuous mandatory ventilation (CMV) assist-control
  2. Inverse ratio ventilation (IRV)
  3. Low-rate intermittent mandatory ventilation
  4. Low inspiratory flows
  a. 1 and 3 only
  b. 1, 3, and 4 only
  c. 3 and 4 only
  d. 2, 3, and 4 only

Question 2

Which of the following is the recommended tidal volume for mechanical ventilation in patients with COPD?
 
  a. 4 to 8 ml/kg
  b. 3 to 5 ml/kg
  c. 6 to 8 ml/kg
  d. 10 to 12 ml/kg

Answer to Question 1

ANS: B
High-risk ventilatory support techniques include any method that increases the I:E ratio, espe-cially CMV at a high rate or in the assist-control mode, and approaches that purposefully shorten expiratory time, such as IRV or the use of low inspiratory flow.

Answer to Question 2

ANS: C
The currently acceptable tidal volume for mechanically ventilated patients in acute respiratory failure with normal lungs or with COPD is 6 to 8 ml/kg.
