[Emergency Resuscitation Techniques:Airway, Breathing, and Circulation]

Cardiac arrest causes cerebral anoxia, resulting in loss of consciousness within seconds and irreversible brain damage within 3-5 min. Emergency resuscitation is generally performed on patients in cardiopulmonary or near-cardiopulmonary arrest, i.e., life-threatening conditions, and requires rapid stabilization of the airway, breathing, and circulation(or "ABC")to maintain cerebral perfusion. Generally, the ABC approach represents the order of medical treatment for critically ill patients. It provides supportive care(resuscitation)after ensuring the flow of oxygen supply necessary to sustain life. The most important goal in emergency resuscitation is to ensure a secure airway, without which, resuscitation is hopeless. Clinicians should be prepared daily to avoid missing any opportunity to ensure a secure airway. Even in cardiac arrest, high-quality cardiopulmonary resuscitation is necessary to reduce the duration of cerebral anoxia. An algorithm for this high-quality cardiopulmonary resuscitation is described in this article.
