Table 1: Summary of the different strategies of cardiopulmonary resuscitation

and use of automatic external defibrillators.

Strategy

Advantages

Disadvantages

• Public access defibrillation

• AEDs on site

• Rapid defibrillation

• High survival rates

• Small impact on survival in private homes

• Difficult predict high-risk areas to place AED

• Need a big number of AED

• Volunteer responders AEDs on site

• Better defibrillation rates when arriving before EMS

• Better defibrillation rates in private homes

• More use of on-site AEDs because been transported to the OHCA

• Big number of volunteer responders and AEDs

• Need an AED register and dispatched center

• Professional first-responders (e.g. police officers) firefighters

• Stations widely spread throughout the community

• Trained in CPR and AED

• Able to enter private homes

• Can be occupied by other jobs and may leave the scene if dispatched to another incident

• Only effective if arrival before EMS

• Drone-delivered AEDs

• AED drone can cover a large area

• Volunteers can move directly to the OHCA location while the drone delivers the AED

• Fast AED delivery before EMS arrival

• Very useful in in rural/and difficult access areas

• Legislation problems

• Needs a trained pilot

• High cost

• Limit used in in with strong winds or

• Heavy rain

AEDs = Automatic External Defibrillators.

CPR = Cardiopulmonary Resuscitation.

EMS = Emergency Medical System.

OHCA = Out-Of-Hospital Cardiac Arrest.
