Abstract

La présente invention concerne un procédé de guidage de réanimation cardiopulmonaire, un dispositif de guidage de réanimation cardiopulmonaire, et un milieu de stockage lisible par ordinateur. Le procédé de guidage de réanimation cardiopulmonaire comprend : l'acquisition d'une forme d'onde d'impédance thoracique d'un·e patient·e à secourir ; la comparaison de la forme d'onde d'impédance thoracique à une forme d'onde prédéterminée, la forme d'onde prédéterminée étant une forme d'onde d'impédance thoracique durant le sauvetage d'un·e patient·e dans une situation idéale ; et l'envoi d'un message d'instruction sur la base d'un résultat de comparaison, le message d'instruction fournissant au sauveteur un guidage pour secourir le·la patient·e. Le procédé de guidage de réanimation cardiopulmonaire fourni dans les modes de réalisation de la présente invention est utile pour diriger un processus réel de sauvetage de réanimation cardiopulmonaire, et aider à garantir la qualité des compressions thoraciques.
