​Differential Diagnosis of Respiratory Acidosis 
• Thoracic cage disorders (pneumothorax, flail chest, kyphoscoliosis)
• Pulmonary disease (chronic obstructive pulmonary disease [COPD], severe pneumonia, pulmonary edema, interstitial fibrosis)
• Failure of mechanical ventilator
• Depression of respiratory center (anesthesia, narcotics, sedatives, vertebral artery embolism or thrombosis, increased intracranial pressure)
• Defects in peripheral nervous system (amyotrophic lateral sclerosis, poliomyelitis, Guillain-Barré syndrome, botulism, tetanus, organophosphate poisoning, spinal cord injury)
• Defects in muscles of respiration (myasthenia gravis, hypokalemia, muscular dystrophy)
• Airway obstruction (foreign body, severe bronchospasm, laryngospasm)
