In the event of a cardiac arrest, time is absolutely crucial. Every second counts.
If somebody collapses lifeless, it is important that you start CPR as soon as possible, preferably within the first 60 seconds, by alternately giving chest compressions and breaths. Do not forget to call 112 and put your phone on loudspeaker. The emergency call operator will guide you through the process. If you feel insecure, keep in mind that it is better to start CPR one time too much than one time too seldom.
It is important to gain access to an AED as soon as possible – early defibrillation is the only way to restore the heart’s rhythm. If you use an AED within 180 seconds, the person’s chances of survival will increase significantly. Call out to someone nearby to fetch an AED and don’t be afraid to use it, it only works if needed.
