Cardiac arrest & resuscitation
Adherence to automated external defibrillator instructions during real-life in-hospital cardiac arrest: an analysis of device data
Authors' conclusion
Adherence to core AED prompts was high, whereas interruptive and corrective instructions were disregarded more frequently.
Study context
- Population
- Professionals using automated external defibrillators (AEDs) during real-life in-hospital cardiac arrest (IHCA) in a German hospital, 2007–2024419 cases analysed
- Participants
- 466 professionals

Main finding
As reported in the abstract
Adherence to AED prompts
Prompt adherence range
15.3% to 81.1%
"start CPR" followed
81.1%
"press shock button" followed
77.7%
"push harder" followed
15.3%
Observational data: associations, not effects.
Further findings
Mean chest compression (CC) depth after "push harder" prompt
- Increased from 3.26 cm to 3.66 cm, 3.61 cm, 3.51 cm
- p < 0.001
Mean CC rate after "push harder" prompt · first interval only
- Improved from 89.8 cpm to 102.2 cpm
- p < 0.001
High-quality CC with adherence to "push harder"
- High-quality CC with adherence to "push harder"
- 54.6%
- p < 0.001
