    Study Notes

    Understanding Respiratory Failure

    • Respiratory failure refers to the inability of the respiratory system to maintain adequate oxygen and/or carbon dioxide exchange.
    • The criteria for respiratory failure in normal individuals are a PaO2 less than 60 mm Hg or a PaCO2 greater than 50 mm Hg.
    • Respiratory failure is life-threatening and can result from virtually any respiratory disorder.
    • There are six major anatomic alterations of the lungs that can cause respiratory failure: atelectasis, alveolar consolidation, increased alveolar-capillary membrane thickness, bronchospasm, excessive bronchial secretions, and distal airway and alveolar weakening.
    • Respiratory failure is commonly classified as hypoxemic (type I), hypercapnic (type II), or a combination of both.
    • Hypoxemic respiratory failure is characterized by inadequate oxygenation and typically demonstrates hypoxemia and a normal or low PaCO2 value.
    • Hypercapnic respiratory failure is characterized by alveolar hypoventilation, resulting in an increase in PaCO2 and a decrease in PaO2 without supplemental oxygen.
    • Hypercapnic respiratory failure is commonly called ventilatory failure and can be acute or chronic.
    • Acute ventilatory failure is characterized by high PaCO2 and low pH, while chronic ventilatory failure is characterized by high PaCO2 and normal pH.
    • Various respiratory disorders are associated with hypoxemic respiratory failure, including restrictive pulmonary disorders, chronic obstructive pulmonary disorders, neoplastic disease, and newborn and early childhood respiratory disorders.
    • Various respiratory disorders are associated with hypercapnic respiratory failure, including neuromuscular disorders, chest wall disorders, and chronic obstructive pulmonary disorders.
    • Treatment of respiratory failure depends on the underlying cause and may include oxygen therapy, mechanical ventilation, bronchodilators, and antibiotics.
