Chapter 30. Management of Extubation of a Patient Following a Prolonged Period of Mechanical Ventilation
Which of the following is a reliable method in assessing airway edema?
A. direct or indirect laryngoscopy prior to extubation
B. ultrasonic evaluation of the vocal cords
C. performing a “cuff-leak test”
D. presence of facial edema
(E) Although all of these methods have been used to assess airway edema, none of them has been proven to be a reliable method in assessing airway edema.
Which of the following are useful steps to minimize the morbidity associated with jet ventilation through a hollow tube exchanger?
A. ensure that the tip of tube exchanger is positioned above the carina
B. avoidance of “breath stacking”
C. use the lowest driving pressure that results in chest expansion
D. ensure adequate muscle relaxation
(E) With the exception of muscle relaxation, all of the listed precautions are useful steps to minimize the morbidity associated with jet ventilation through a hollow tube exchanger.
Which of the following may be helpful to reduce airway edema?
A. elevation of the head of the bed
B. the use of nebulized epinephrine
D. the use of diuretic therapy
(E) All of the steps are helpful to reduce airway edema.
