Respiratory failure

Summary

  • Results from acute or chronic malfunctions in gas exchange between the lungs and the blood causing hypoxia with or without hypercapnia.
  • Patients may present with SOB, anxiety, confusion, tachypnoea, cardiac dysfunction, and cardiac arrest. CNS depression can occur as a result of lack of oxygenation of the blood and vital organs or excessive accumulation of carbon dioxide.
  • Pulse oximetry, chest x-rays, and blood gas analysis are key diagnostic tests.
  • Initial management involves ensuring that the upper airway is patent and clear of obstructions. Subsequent management involves supplemental oxygenation and ventilatory support with immediate attention to the underlying cause or causes for respiratory failure.
  • Endotracheal intubation and mechanical ventilation are employed when other less invasive manoeuvres have failed.
