Respiratory lesions

The cause of respiratory accidents may be:

  • Obstruction of the respiratory tract.
  • Poor air quality..
  • Difficulty in respiratory movements (crushing, beating or thorax wounds).

If any of the indicated causes persist, it may lead to respiratory arrest needing pulmonary reanimation. If the brain does not receive oxygen (anoxia) promptly, 60% of its functions may be destroyed in four minutes (clinical death) and close to 100% in ten minutes (cerebral or biological death).

The most characteristic sign of lack of breathing is a blue coloration to the skin and lips called cyanosis.
