RESUMEN
Cardiac arrest is a leading cause of mortality globally, and mechanical CPR devices like the LUCAS system are designed to improve outcomes by enhancing consistency and reducing rescuer fatigue. However, this case report of a 76-year-old female who suffered cardiac arrest post-flight reveals significant complications associated with mechanical CPR. Despite achieving initial resuscitation, she developed extensive liver damage and additional complications, which ultimately led to her death. This case underscores the importance of precise training and strict adherence to guidelines when using mechanical CPR devices. It highlights that while these devices offer potential benefits, they also pose risks, especially for vulnerable patients, necessitating careful consideration and ongoing evaluation to optimize safety and effectiveness.
