Without any electricity or battery – purely mechanically – is the Cardio First Angel always on standby. Its applicability is shown in uncomplicated and international comprehensible icons.
The specific design of the Cardio First Angel guarantees the correct positioning on the patients breast, so the cardiac massage works exactly where it is needed. A special foam creates a soft contact surface and absorbs sudor.
A special spring signalises the perfect pressure of 41 kg with a clear click-sound. The click-sound is also audible with the following release of the spring. If the first-aider is geared to these two click-sounds he will automatically reach the required frequency of round about 100 compressions per minute.
