AI Technical Summary

Technical Problem

Conventional fully automated AEDs require complete power shutdown to cancel a defibrillation process, leading to a waiting period before electrocardiogram analysis can be resumed, which may not align with rapid changes in a patient's cardiac function.

Method used

An automated external defibrillator that determines whether electrode pads are attached and if a predetermined operation is performed, allowing the defibrillation process to be canceled while the device remains powered on, thereby maintaining continuous electrocardiogram analysis.

Benefits of technology

Enables immediate cancellation of the defibrillation process without powering off, enhancing usability by allowing continuous electrocardiogram monitoring and reducing the need for initialization processes, thus improving operational efficiency.

Abstract

To improve usability of an automated external defibrillator (AED).SOLUTION: An AED is configured so as to automatically carry out defibrillation processing for giving an electric shock for defibrillation to the heart of a subject. The AED acquires a biological signal of the subject through an electrode pad, determines whether or not the defibrillation processing is required on the basis of the biological signal, and determines whether or not the electrode pad is mounted on the subject, and whether or not a predetermined operation has been carried out for the AED. In the case where the defibrillation processing is required, the defibrillation processing is cancelled while the on-state of the power of the AED is maintained according to the result of the determination on whether or not the electrode pad is mounted on the subject and on whether or not the predetermined operation has been carried out for the AED.SELECTED DRAWING: Figure 4
