First Aid: a sensor to respond more effectively

Germany - As part of a federal project, researchers at the Research Center Karlsruhe have developed a mini-sensor capable of identifying the status of an unconscious person and to administer first aid.

This small sensor is as big a nut and able to recognize the presence of small movements or respiratory pulse. In less than ten seconds, it can inform the patient through a light signal and allow the administration of care. When the sensor is reliable up to 90%, Dr. Jäger, project manager, aims to achieve 96% accuracy.

The sensor emits a signal in light green or red. In the latter case, resuscitation was needed. If it is green, simple measures such as isolation or elongation of the patient may be sufficient. Dr. Jäger explains: "Many people who arrive first on the scene of an accident, can not estimate exactly the emergency. And this is a good estimate of the situation which will improve the quality of assistance offered. Compared to an oximeter or a defibrillator, the sensor is small, fast, reliable and inexpensive.

The marketing of the sensor is planned during the year with a starting price of between € 35 and 40 that Dr. Jäger wants to fall in the long term to reach 10 to 20 €. Police officers, firefighters and emergency doctors who tested the device have all adhered to that formula. Companies and pharmacies have also expressed interest.
