A map of every defibrillator in Perth and Kinross is to be made available to the public.
The local authority is compiling the list of life saving machines in a bid to make them more accessible in emergency situations.
The council has also installed an extra 14 automated defibrillator in council buildings across the region.
Alan Stewart, first aid advisor to Perth and Kinross Council said: “The next step is to make them more available to the public by mounting them outside.
“We are also developing a map, which will be available to the public, showing where public-access defibrillators are available throughout the whole of Perth and Kinross.
“We are just about there – we have a prototype, which we need to finalise. We are continually adding more defibrillators that we don’t know about, which is really, really good. The map will never be finalised, it will be an ongoing thing that we will add to.
“The sooner you can get a defibrillator to a casualty, the greater their chance of survival. This map will definitely save lives – we need to make people aware of where they are.”
A spokeswoman for Perth and Kinross Council said: “When someone has a sudden cardiac arrest, treatment needs to begin within three to five minutes of the attack for the best chance of full recovery.
“Automated external defibrillators are easy to use, compact and portable. They are designed to be used by an untrained person as the machine will guide the operator through the process with verbal instructions and visual prompts.
“The machine will not allow a shock to be delivered if the patient’s heart rhythm does not require it.
“The machines are designed to be stored for long periods without use and requires very little routine maintenance.
“We can confirm that the council is currently looking into the prospect of using the mapping feature with regard to the defibrillators.”
Some of the new locations include the AK Bell Library, Perth Museum and Art Gallery, and The Fergusson Gallery and Perth Crematorium.
The council has also installed defibrillators at Perth Grammar and Perth High, meaning all high schools in Perth and Kinross now have one on site.
