The most common reasons of a cardiac arrest are cardiac arrhytmia and structural heart diseases. In the first four-five minutes of the cardiac arrest, there is still enough oxygen in the human body’s circulatory system to maintain the perfusion of the organs and tissues. In order to keep the blood and oxygen supply at an adequate level during a cardiac arrest, we have to start the chest compressions with periodic ventilations as soon as possible.
The chest compressions should be performed with an appropriate speed and compression depth in the interest of effective outcome. A CPR (cardiopulmonary resuscitation) feedback device could monitor the pertinence of the chest compressions.
My master's thesis contributes to the development of a clinical defibrillator, which is able to monitor the quality of the chest compressions continuously during the resuscitation. My goal is to create a CPR feedback module, which should be placed on the patient’s chest, so that the compressions are performed through the device. Utilizing the data collected from the CPR module’s sensors, a continuous feedback can be given to the rescuer, which can aid the performance of the chest compressions.
