First aid alert system

from Wikipedia, the free encyclopedia

The term first aid alert system includes all technical means and their interaction for alerting qualified first aiders in medical emergencies. Depending on the design of the first aid system, different technologies are used.

Smartphone-based solutions are usually used, which is why first-aider alerting systems are often referred to simply as "first-aiders app". The smartphone enables regular tracking, so potential helpers can be alerted depending on their position.

Known systems

First aid alert systems are used internationally. The following list gives an overview of different systems.

  • corhelper
  • FirstAED
  • GoodSam (mainly in the UK)
  • Save my city
  • Mobile rescuers
  • PulsePoint (mainly USA)
  • SMS Livräddare (Sweden)
  • Ticino Cuore (Switzerland)
  • United Hatzalah (Israel, semi-professional organization with its own alarm system)

Systems from corhelper, Meine Stadt Rettet, Mobile Retter, and FirstAED are active in Germany.

background

With various time-critical emergency pictures, it is of essential importance for the patient's outcome that he or she receives qualified help without delay. A prominent example is cardiovascular arrest. Here, a reduction in the probability of survival by approx. 10% is to be expected per minute of delay in therapy. If help is given before the rescue service arrives, a significant increase in the probability of survival can be expected.

In Germany, for example, the lay resuscitation rate is only around 35% - in other words, only a very small part of the population actually provides help to those affected when the cardiovascular system has stopped. In Germany, however, the rescue service is only on site after about 8.5 minutes. There is therefore a clear so-called therapy-free interval between the occurrence of the emergency and the start of qualified relief measures - the relief measures always start too late.

The common goal of all first aid alert systems is to shorten the therapy-free interval in time-critical emergency situations. For this purpose, volunteers who happen to be in the vicinity are alerted to the emergency site in order to provide quick and qualified help there. When using a first-aid alarm system, a significant increase in the resuscitation measures started before the emergency services arrived can be observed. The systems thus contribute to a more community-focused approach that the ERC sees as a key element in improving cardiac arrest survival outside the hospital.

First-aider alerting systems are sensibly connected to the local rescue control center so that the first-aiders can be alerted to the emergency services without any delay. Various interfaces of the control center software are available for this.

There is no scientific evidence of an improvement in the survival rate in cardiovascular arrests. Investigations of a system used in Stockholm could not find any significant improvement. Nevertheless, a system was used here that is based on triangulation-based location of the users. In addition, the system relied on the use of previously laypeople - the quality of the cardiopulmonary resuscitation was not examined. More modern systems, such as those used in Germany, use more precise, GPS-based location technology, thus possibly enabling a narrower alerting radius. Some of the systems also rely on the potential of trained helpers already existing in the population instead of lay helpers.
