When the patient stabilizes on mechanical ventilation with a PEEP of 12 cm H2O and the FiO2 has been reduced to 0.40, how should the PEEP level reduce?
 
  a. In increments of 2 cm H2O every 6 hr
  b. In increments of 3 to 5 cm H2O every 2 hr
  c. In increments of 3 to 5 cm H2O every 1 hr
  d. In increments of 5 cm H2O every 2 hr

Question 2

When is the PEEP/CPAP level optimum?
 
  a. O2 delivery to the tissues is maximized.
  b. Pressures are maintained below 15 cm H2O.
  c. CaO2-CvO2 is maximized.
  d. The PaO2 is 60 to 100 mm Hg.

Answer to Question 1

ANS: A
After reduction of the FiO2 to 0.40, PEEP can be reduced gradually as the patient improves at a rate of 2 cm H2O every 6 to 8 hr.

Answer to Question 2

ANS: A
Optimal or best PEEP may be defined as the PEEP that maximizes O2 delivery (DO2).
