RS has smoked for many years and has developed chronic bronchitis, a chronic obstructive pulmonary disease (COPD). He also has a history of pulmonary hypertension and secondary polycythemia vera. His arterial blood gas (ABG) reveals respiratory acidosis with a PaO2, at 50 mm Hg and a PaCO2, at 60 mm Hg; At this clinic visit, it is noted on his chest x-ray, RS has an enlarged heart and diaphragm flattening.

  1. What pulmonary clinical signs and symptoms is RS exhibiting from chronic bronchitis?
  2. Why has RS developed secondary polycythemia vera?
  3. What clinical effects would RS’s respiratory disease have on his cardiovascular function?

Answer #1

Chronic bronchitis is a disease state characterized by airflow obstruction and progressive airflow obstruction occurs ,associated with an abnormal inflammatory response of the lungs that is not completely reversible.

The signs and symptoms include:

cough ,exertional dyspnoea,wheezing and crackles,sputum production,barrel chest,pronlonged expiration,Abg levels indicate respiratory acidosis and hypoxemia

Chronic obstructive pulmonary disease leads to secondary polycythemia and it is due to the less oxygen supply in the tissue

As a result of COPD the oxygen level is decrased this makes  the blood pressure of the lungs is increased.This is known as pulmonary hypertension. The signs include shortness of breath,chest pain,fatigue, palpitation and so on
