Which of the following are potential benefits of using noninvasive ventilation (NIV) during weaning?

1. Reduced length of intensive care unit (ICU) stay
2. Reduced incidence of nosocomial pneumonia
3. Reduced mortality rate
4. Reduced incidence of pulmonary embolism
a. 1 and 3 only
b. 1, 2, and 3 only
c. 3 and 4 only
d. 2, 3, and 4 only

Question 2

The use of noninvasive ventilation (NIV) in the long-term care of patients with chronic obstruc-tive pulmonary disease (COPD) will benefit the patient in which the following ways except:

1. better gas exchange.
2. improved sleep quality.
3. resetting the respiratory center to better respond to hypoxemia.
4. unloading the respiratory muscles.
a. 1 and 3 only
b. 1, 2, and 4 only
c. 2 and 4 only
d. 2, 3, and 4 only

Answer to Question 1

ANS: B
In one study, it was found that NIV reduced weaning time, length of ICU stay, incidence of nosocomial pneumonia, and 60-day mortality compared with conventional weaning with invasive pressure support ventilation.

Answer to Question 2

ANS: B
First, positive inspiratory pressure may improve gas exchange and unload the respiratory muscles, allowing these muscles to recover, gain strength, and reduce fatigue. These benefits should re-duce symptoms associated with hypoventilation and improve quality-of-life. Second, patients with severe COPD have poor sleep quality, shorter sleep time, and nocturnal hypoventilation.
