However, the effectiveness of CPR is currently less than satisfactory, and even if performed by professional medical practitioners, manual chest compressions can be only 28% of the quality required by guidelines, with non-professional compressions of lower quality, which can greatly affect resuscitation success and patient survival.

Some products are currently on the market abroad, including full Automatic External Defibrillators (AEDs) developed by ZOLL, which have a feedback system of real-time compression depth and frequency, which can improve compression quality, automated cardiopulmonary resuscitation (AutoPulse) systems, which can perform automatic full thoracic chest compressions, automated extrathoracic compression devices LUCAS developed by JOLIFE AB, etc., while products in this field are still blank at home and lack of timely feedback and individualized adjustment of compression depth. It is noteworthy that although these products increase compression quality compared to artificial chest compressions, they do not show advantages in clinical studies in terms of patient resuscitation success, survival, and other major outcome measures. This may be associated with missing the optimal resuscitation time due to too long installation time of the device, affecting the compression effect due to the difference in compression depth and frequency due to individual differences, failing to adjust the resuscitation procedure in time following the change of the organism's life index due to lack of a real-time feedback system, failing to determine the opportunity and effect of resuscitation due to lack of medical expertise in home use, etc.
