Which of the following is the primary reason to teach pursed-lip breathing to clients with emphysema?
A. To promote oxygen intake.
B. To strengthen the diaphragm.
C. To strengthen the intercostal muscles.
D. To promote carbon dioxide elimination.
Correct Answer: D. To promote carbon dioxide elimination.
Pursed lip breathing prolongs exhalation and prevents air trapping in the alveoli, thereby promoting carbon dioxide elimination. By prolonged exhalation and helping the client relax, pursed-lip breathing helps the client learn to control the rate and depth of respiration. Pursed-lip breathing does not promote the intake of oxygen, strengthen the diaphragm, or strengthen intercostal muscles.
Option A: For those suffering from chronic obstructive pulmonary disease, the ability to take in oxygen is a constant struggle. It’s possible to increase oxygen levels in other ways, such as cellular therapy. Cellular therapy may promote the healing of lung tissue, potentially improving lung function. When lung function improves, the client is able to take in more oxygen as well as expel carbon dioxide because the lungs are working more effectively.
Option B: Diaphragmatic breathing is a type of a breathing exercise that helps strengthen the diaphragm, an important muscle that helps us breathe. This breathing exercise is also sometimes called belly breathing or abdominal breathing.
Option C: Breathing exercises slowly fill the lungs with air to expand the chest and work the intercostal muscles. To do this exercise, it is typically recommended to sit or stand with the back straight, then take a full breath from the bottom of the lungs. It can help to think of breathing from the diaphragm, by slowly expanding the abdominal muscles while inhaling, then pushing air from the lungs using these same muscles.
