Chronic Bronchitis: Disease of
Hypersecretion
• In chronic bronchitis, the alveoli become damaged and
inflamed due to excessive mucus production, leading to
impaired gas exchange.
• The alveoli may become filled with mucus, reducing
surface area for gas exchange.
• Hypoxemia (low oxygen levels in the blood) may result
and can lead to further complications if left untreated.
Pulmonary Hypertension and Cor Pulmonale
• Pulmonary hypertension, or increased blood pressure in
the pulmonary artery, is a common complication of
chronic bronchitis.
• Cor pulmonale, or right-side heart failure, can occur as a
late complication of chronic bronchitis due to the
increased workload on the right ventricle caused by
pulmonary hypertension.
• Symptoms of cor pulmonale include peripheral edema
(swelling in the legs, ankles, and feet) and jugular venous
distention.
Edema in Chronic Bronchitis
• Edema, or fluid buildup in the tissues, can occur in
chronic bronchitis due to several reasons, including
, hypoxemia, increased capillary permeability, and
decreased oncotic pressure.
• Peripheral edema can be a symptom of cor pulmonale,
but edema can also occur in other parts of the body,
such as the lungs.
• Pulmonary edema can further impair gas exchange and
lead to respiratory failure.
Alveoli and Gas Exchange
• Alveoli are tiny air sacs in the lungs where the exchange
of oxygen and carbon dioxide occurs.
• The process of gas exchange involves the diffusion of
oxygen from the alveoli into the bloodstream and the
