Mr Hutchinson said this process for anyone involved 30 compressions to two breaths and wanted people to know that compressions are the most important part.
"Chest depth is 1/3, so for an adult we say 4-5cm and children 2-3cm."
For an adult the heel of one hand is placed in the centre of the chest and the heel of the other hand is placed on top of the first hand. You then keep your elbows locked and lean over the patient so your arms are straight. You then push down hard and fast 30 times.
For a child just one hand is placed in the centre of the chest but if it is too hard then the other hand is placed on top, like what happens for an adult.
To breathe into the patient two times take a deep breath, seal your lips around the patient's mouth and block the nose by pinching the soft part of the nose or push it with your cheek. Blow into the patient's mouth until you see the chest rise.
To help with CPR first aid instructors are teaching people to perform it to any song that has 100-120 beats per minute.
"It is true the Bee Gees' Staying Alive is one to do it to as it has that 100-120 beats per minute, it is a helpful way to remember," Mr Hutchinson said.
If an AED is available it should be attached to the patient as soon as possible to help with the process.
A heart defibrillator is crucial towards regaining that natural rhythm of the heartbeat as well as restarting the heart.
"We are seeing a 16 per cent increase in the survival rate when early CPR and defibrillators are used. We think more are doing first aid courses and more businesses have defibrillators inside."
An AED gets attached to the patient via the pads. One pad is placed under the left armpit on the bare skinned chest while the other is placed under the collarbone on the right side of the bare skinned chest.
Mr Hutchinson said St John wants people to stay safe while enjoying what Hawke's Bay has to offer this summer.
"Everyone has to look out for each other. We would rather have a quiet summer than a busy one and I am sure people don't want to see us so just stay safe."
A useful application people should have on their android or iPhone this summer is the St John's CPR and AED app, which provides detailed instructions and tutorials on CPR and AED.
Mr Hutchinson said if someone was about to give CPR the app would actually talk them through it step by step.
