Cardiopulmonary resuscitation (CPR) is a combination of life-saving techniques used to restore normal body functions. If a person stops breathing or their heart stops beating, consistent use of CPR can actually revive the heart and restore normal breathing patterns.

CPR consists of a combination of oral resuscitation and, if necessary, chest compressions. Basically, the person using CPR breaths for the victim and manually pumps the victim's heart until normal function is restored.

It is clear that in a life-threatening situation, apart from providing CPR, you will call the emergency services the right way.

CPR first aid training is for those who have a specific job – school, nursing home, etc. – but that doesn't mean that not everyone, regardless of career, should have a basic understanding of CPR. 

The CPR First Aid course provides you with invaluable safety and preparedness in an emergency. This course is usually completed in one day. A licensed instructor will walk you through the steps of CPR, and you can even practice these steps on a mannequin.

You will usually get a CPR certification card at the end of the course. Even if you have taken CPR first aid courses in the past, it is always a good idea to renew your certificate annually.
