Which of the following statements is correct concerning endotracheal tube cuff management?
 
  a. The cuff should be deflated every hour to minimize pressure on the trachea.
  b. A small leak should be heard on inspiration if the cuff has been inflated using the minimal leak technique.
  c. Cuff pressures should be kept between 40 to 50 mm Hg to ensure an adequate seal.
  d. Cuff pressure monitoring should be done once every 24 hours.

Question 2

Contractility of the left side of the heart is measured by

  c. systemic vascular resistance.
  d. left ventricular stroke work index.

Answer to Question 1

B
The minimal leak technique consists of injecting air into the cuff until no leak is heard and then withdrawing the air until a small leak is heard on inspiration. Problems with this technique include difficulty maintaining positive end-expiratory pressure and aspiration around the cuff.

Answer to Question 2

D
Contractility of the left side of the heart is measured by the left ventricular stroke work index.
