What is the value of determining the lower inflection point during measurement of the pres-sure-volume curve?
 
  a. Best tidal volume
  b. Best PEEP level
  c. To determine best airway size
  d. To determine type of ventilator inspiratory flow pattern

Question 2

What is the normal range for lung compliance?
 
  a. 40 to 60 ml/cm H2O
  b. 60 to 100 ml/cm H2O
  c. 80 to 120 ml/cm H2O
  d. 100 to 120 ml/cm H2O

Answer to Question 1

ANS: B
A recommended strategy for setting PEEP is to set a level slightly above the lower inflection point with the goal of recruitment and stabilization of dependent alveoli that would otherwise sustain injury from repetitive opening, closing, and reopening during tidal ventilation.

Answer to Question 2

ANS: B
Normal compliance ranges between 60 and 100 ml/cm H2O.
