Enfermedad pulmonar obstructiva crónica (EPOC)

La enfermedad pulmonar obstructiva crónica (EPOC) se refiere a un trastorno pulmonar crónico que da como resultado un bloqueo en el flujo de aire en los pulmones. Los dos principales trastornos EPOC son el enfisema y la bronquitis crónica, las causas más comunes de insuficiencia respiratoria. El enfisema se presenta cuando las paredes entre los sacos de aire del pulmón se debilitan y colapsan. Por lo general, la lesión que causa la EPOC es permanente e irreversible.
