Why are patients with emphysema prone to exhaustion?
The damaged alveoli release chemicals that simulate the pain receptors. The unrelenting messages of pain cause the patient to be fatigued.
- B.
Because the alveoli are damaged, the natural recoil that comes from the surrounding elastic fibers is diminished and the patient must activate muscles to exhale.
- C.
The immune system is prompted to wall off areas of damage, preventing both ventilation and perfusion. The diminished air and blood supply cause a hypercapnia that results in fatigue.
- D.
The increased amounts of mucus and inflammation makes it challenging to pull air into the lungs, causing it to be trapped once it's in the alveoli. Accessory inspiratory muscles must be used to maintain ventilation.
- E.
the ciliated epithelium moves debris to the bronchioles, creating an obstruction and irritation. The act of continually coughing cases the patient to grow fatigued.
