The formula used for the calculation of static compliance (CS) is which of the following?
 
  a. (Peak inspiratory pressure (PIP)  EEP)/tidal volume (VT)
  b. (Plateau pressure (Pplateau)  EEP)/tidal vo-lume (VT)
  c. Tidal volume/(plateau pressure  EEP)
  d. Tidal volume/(peak pressure (PIP)  pla-teau pressure (Pplateau))

Question 2

The respiratory therapist should expect which of the following findings while ventilating a pa-tient with acute respiratory distress syndrome (ARDS)?
 
  a. An elevated plateau pressure (Pplateau)
  b. A decreased elastic resistance
  c. A low peak inspiratory pressure (PIP)
  d. A large transairway pressure (PTA) gradient

Answer to Question 1

ANS: C
CS = VT/(Pplateau  EEP)

Answer to Question 2

ANS: A
ARDS is a pathological condition that is associated with a reduction in lung compliance. The formula for static compliance (CS) utilizes the measured plateau pressure (Pplateau) in its denomi-nator (CS = VT /(Pplateau  EEP). Therefore, with a consistent exhaled tidal volume (VT), an ele-vated Pplateau will decrease CS.

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.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
