Which of the following statements are true about intermittent positive-pressure breathing (IPPB)?

1. IPPB could cause lung overinflation.
2. IPPB could cause no expansion of regions affected by secretions.
3. Bronchial hygiene must be used in conjunction with IPPB to adequately manage secretions.

Answer to Question 1

ANS: B
In either case, IPPB should not be used as a single treatment modality for the patient with gas absorption atelectasis due to excessive airway secretions. Applying positive pressure to the lung in such cases is likely to cause overinflation of the lung regions not affected by secretions and minimal or no expansion of the affected lung segments. Bronchial hygiene with humidity therapy must be used in conjunction with IPPB for the most optimal results in such cases.

Answer to Question 2

ANS: A
The optimal breathing pattern to reinflate collapsed lung units with IPPB consists of slow, deep breaths that are sustained or held at end-inspiration.
