more lives

Since 2018, the German non-profit foundation Region of Lifesavers
has established a systematic use of registered first responders
based on a highly respected Danish system, which has been
in operation since 2012.
In co-operation with local emergency dispatch centers, we make
it possible to alert community first responders in the vicinity of
a cardiovascular arrest.
These professional rescuers, who often arrive only 3-5 minutes
after a cardiac arrest, can double or quadruple the chance of
patient survival. Our approach:

Your help ? – just a click away.
