  a. Inspiratory pause c. Pressure-control ventilation
  b. End-expiratory pause d. Pressure-release ventilation

Question 2

What is the static lung compliance when the returned tidal volume is 460 mL, the positive end-expiratory pressure is 8 cm H2O, the peak inspiratory pressure is 27 cm H2O, and the plateau pressure is 18 cm H2O?
 
  a. 20 mL/cm H2O c. 46 mL/cm H2O
  b. 26 mL/cm H2O d. 51 mL/cm H2O

Answer to Question 1

ANS: B
End-expiratory pause, or expiratory hold, is a procedure performed to estimate the pressure in the patient's lung and ventilator circuit caused by trapped air.

Answer to Question 2

ANS: B
Static lung compliance = Volume  (Plateau pressure  Positive end-expiratory pressure) = 460 mL  (18 cm H2O  8 cm H2O) = 460 mL  10 cm H2O = 46 mL/cm H2O.

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.
