Use this figure to compute the static compliance (CS) for an intubated patient with an exhaled tidal volume (VT) of 500 mL.
 
  a. 14 mL/cm H2O
  b. 20 mL/cm H2O
  c. 33 mL/cm H2O
  d. 50 mL/cm H2O

Question 2

Evaluate the combinations of compliance and resistance and select the combination that will cause the lungs to empty slowest.
 
  a. CS = 0.05 L/cm H2O Raw = 2 cm H2O/(L/sec)
  b. CS = 0.05 L/cm H2O Raw = 6 cm H2O/(L/sec)
  c. CS = 0.03 L/cm H2O Raw = 5 cm H2O/(L/sec)
  d. CS = 0.03 L/cm H2O Raw = 8 cm H2O/(L/sec)

Answer to Question 1

ANS: D
Cs = Pplateau  EEP; the Pplateau in the figure is 20 cm H2O and the PEEP is 10 cm H2O.

Answer to Question 2

ANS: B
Use the time constant formula, TC = C  R, to determine the time constant for each choice. The combination with the longest time constant will empty the slowest. The time constant for A is 0.1 second, B is 0.3 second, C is 0.15 second, and D is 0.24 second. To find out how many seconds for emptying, multiply the time constant by 5.

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
