Respiratory failure

Respiratory failure is a life-threatening condition in which the lungs are unable to adequately exchange oxygen and carbon dioxide. It is characterized by shortness of breath, rapid breathing, and an inability to breathe deeply. It can develop quickly or slowly, depending on the underlying cause. Symptoms may include confusion, drowsiness, and bluish skin color. Treatment depends on the cause and may include oxygen therapy, mechanical ventilation, and medications to support breathing.
