Mechanical resuscitation aid
Mechanical resuscitation aids are devices that are used for resuscitation in the preclinical and clinical area . They perform the compressions of the thorax independently during resuscitation or they facilitate it mechanically. They are intended to ensure more effective resuscitation of the patient by preventing or reducing symptoms of fatigue and inaccuracies in chest compression by the rescuer. Fully automatic devices also offer the advantage that the helper, who was previously responsible for chest compressions, can carry out further measures after the device has been put on, and that transport is made possible while resuscitation is ongoing without the usual loss of quality. Furthermore, a cardiac catheter examination can take place with ongoing resuscitation, without another person having to expose themselves to the X-rays during the fluoroscopy.
A disadvantage of all devices is that they cannot be used with patient groups such as small children or very overweight people and that the emergency services personnel have to take another device to the patient. In addition, the manual chest compressions must be interrupted in order to apply the device.
The devices that first came onto the market under the names Thumper (for thoracic compression), Cardio Pump (developed in 1992 with active compression-decompression, ACD) or "Lifestick" (with sequential thoraco-abdominal ACD technology) were to become available Orientate yourself to the current guidelines of the ERC on the subject of resuscitation, related to pressure depth, pressure point and frequency of compressions. These guidelines emphasize that extended resuscitation attempts, for example during thrombolytic therapy in patients suspected of having a pulmonary embolism , are made possible with mechanical resuscitation aids in selected patients and that high-quality chest compressions are also carried out during transport with a rescue device or during a cardiac catheter examination can be.
These devices are used in both clinical and pre-clinical areas. Studies focus on the improvement of the coronary blood flow , the recurrence of an independent blood circulation (so-called return of spontaneous circulation ) and the outcome of the patient, especially related to the survival of the acute cardiac arrest as well as the survival after several days and the neurological outcome (neurological Damage to the patient). The results of the study differ greatly from device to device. A study from Vienna found poorer survival probabilities when using the LUCAS system, but these were not statistically significant. As far as we know from 2015, routine use for every resuscitation is not justifiable.
