CNS status ranges from wide awake to lethargic and from agitated to comatose. As hypoxemia progresses, lethargy progresses to agitation caused by air hunger. As more lung units become obstructed, hypoxemia worsens and hypercarbia develops. Both hypoxemia and hypercarbia can lead to seizures and coma and are late signs of respiratory compromise.
