Good basic life support (BLS) can mean the difference between survival and death in the event of a person suffering a cardiac arrest. Whether this is in the community or in a hospital setting, the same principles of providing fast, early help apply. As students you are required to complete mandatory training in BLS every year (and this will continue in future health and care settings where you will work), but do we always recognise the importance of this skill? In the video below (from the British Heart Foundation) a man suffers an out of hospital cardiac arrest. His friend quickly recognises this and calls for help, whilst beginning basic life support through early CPR. Soon after the defibrillator arrives with the Ambulance Service, the patient receives early defibrillation from the paramedic and further high quality CPR. All of these steps are outlined below in the Chain of Survival. These are the simple recognised steps involved in resuscitation which we know improve outcomes from cardiac arrest. The patient goes on to make a full recovery. The video reinforces how BLS truly is a lifesaving skill to have!
Please also see the page on Clinical Skills Repository page on Airway Management for information surrounding airway adjuncts you may see used during resucitation.
The chain of survival from the European Resuscitation Council
The chain is only as strong as its weakest link; all four links in the Chain of Survival must be strong (Resuscitation Council UK, 2026).
WARNING: Viewer discretion is advised - contains scenes of a real life cardiac arrest and resuscitation attempt.

Click on the button below to navigate to the 'Assessments' area of ClinicalSkills.net. Please make sure you're logged into ClinicalSkills.net already, otherwise you may not be able to open and take the test. Once you have reached the 'Assessments' area, select 'Standard Assessments' and then click on the test called 'Cardiopulmonary resuscitation (CPR) in infants and children' to begin. You will need to score 80% or more to pass. Make sure you've read the ClinicalSkills.net procedures thoroughly before taking the test as many of the answers will be found within there!
