... [1][2][3][4] In witnessed OHCA, patients who received bystander CPR had approximately twice the one-month survival rate compared to those who did not receive bystander CPR. 5 Bystanders who may not recognize cardiac arrest or have no prior CPR experience are encouraged to perform dispatcher-assisted CPR (DA-CPR), thereby increasing the chance of survival. [6][7][8][9] DA-CPR assists CPR by allowing the dispatcher to determine whether the patient is in cardiac arrest status and to provide instructions for chest compressions and ventilation or only chest compressions. 9,10 DA-CPR has a lower survival rate compared to public bystander-initiated CPR 9 ; this disparity in survival may be associated with the gender of those performing DA-CPR, 10 although this relationship has not been clearly examined. ...

... Cardiopulmonary arrest (CPA) is one of the most common causes of death in middle and old age, with a high mortality rate even when patients receive appropriate treatment, including immediate cardiopulmonary resuscitation (CPR), defibrillation such as automated external defibrillation, and emergency medical services (EMS) [1][2][3][4]. The interval from patient collapse to defibrillation is recognized as a critical survival factor, significantly influencing favorable neurological outcomes in CPA patients [3,[5][6][7][8][9]. ...
