Acute respiratory failure in COPD: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

In patients who have COPD with ARF, increased ventilation-perfusion mismatch and reduced alveolar ventilation decrease PaO₂ (hypoxemia) and increase Paco₂ (hypercapnia). This rise in carbon dioxide (CO₂) lowers the pH. The resulting hypoxemia and acidemia affect all body organs, especially the CNS and the respiratory and cardiovascular systems.

Specific symptoms vary with the underlying cause of ARF but may include these systems:

❑ Respiratory — Rate may be increased, decreased, or normal depending on the cause; respirations may be shallow, deep, or alternate between the two; and air hunger may occur. Cyanosis may or may not be present, depending on the hemoglobin (Hb) level and arterial oxygenation. Auscultation of the chest may reveal crackles, rhonchi, wheezing, or diminished breath sounds.

❑ CNS — When hypoxemia and hypercapnia occur, the patient may show evidence of restlessness, confusion, loss of concentration, irritability, tremulousness, diminished tendon reflexes, and papilledema; he may slip into a coma.

❑ Cardiovascular — Tachycardia, with increased cardiac output and mildly elevated blood pressure secondary to adrenal release of catecholamine, occurs early in response to low PaO₂. With myocardial hypoxia, arrhythmias may develop. Pulmonary hypertension, secondary to pulmonary capillary vasoconstriction, may cause increased pressures on the right side of the heart, elevated jugular veins, an enlarged liver, and peripheral edema. Stresses on the heart may precipitate cardiac failure.
