Precision timing in public-access defibrillation: a study of time-stamped data recorded by automatic external defibrillator from railway stations

ResuscitationPublished retrospective observational study

Authors' conclusion

Second-by-second AED log data in real world can provide valuable insight into the actual implementation of PAD programs. Railway stations are high-impact locations for AED deployment, and such data can provide a practical benchmark for assessing and improving AED accessibility.
