Which of the following statements are true concerning prone positioning ARDS patients during mechanical ventilation?
 
  A. Patients who have ARDS from septicemia respond better than patients who have ARDS from direct lung injury.
  B. Patients who develop ARDS from direct lung injury respond better than those who get ARDS from nonlung injury.
  C. Prone positioning reduces length of ICU stay and decreases mortality associated with ARDS.
  D. Prone positioning offers improved oxygenation, but does not improve mortality.

Question 2

The therapist is mechanically ventilating a patient who has multiple lung abscesses from a Staphylococcus aureus infection in right middle and lower lobes. Based on this information, in what position should the therapist mechanically ventilate this patient?
 
  A. supine
  B. left lateral decubitus
  C. right lateral decubitus
  D. prone

Answer to Question 1

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: Based on early results, a number of randomized early controlled trials of prone positioning ARDS patients were undertaken. These studies consistently confirm that the prone position improves oxygenation when compared with the supine position. However, the prone position appears to offer no mortality benefit compared with supine positioning in patients with acute lung injury.

Answer to Question 2

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Good lung down positioning is contraindicated for patients who have pulmonary hemorrhage and lung abscess because of the risk of spillage of blood or pus into the uninvolved (dependent) lung. Another exception to the good lung down rule involves patients who have unilateral pleural effusion, where lateral decubitus positioning does not appear to affect ventilationperfusio n matching or oxygenation.
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B.
