It is necessary to immediately begin appropriate resuscitation and at the same time arranging for possible hospital care.
Clinically, the presentation of a patient with cardiac arrest is that of sudden loss of consciousness accompanied by loss of pulsation in any major artery such as femoral or carotid. The speed of pre-hospital care is the key since even very minor delays may adversely affect prognosis (Ewy, 2007). It has been recommended that the time taken to assess the circulation in such patients should not exceed more than 10 seconds, and wasting time for noting other confirmatory clinical features would be waste of time without any contribution to the diagnosis.
In fact taking care of the patients with cardiac arrest in the pre-hospital settings is one of the defining characteristic EMS of professionals since they are trained to recognize and manage the undifferentiated patient with cardiac arrest, although this can be most effectively accomplished through an appropriate understanding of the pathophysiology of cardiac arrest and developing ability and skills to correlate the principles behind the resuscitation of these patients to those pathophysiological events. Although a qualified physician is always involved in such resuscitation teams, the care is delivered by the paramedical staff.
However, that does not in any way lead to compromise in the quality of such services since modern cardiopulmonary resuscitation techniques such as closed chest cardiac massage, mouth-to-mouth ventilation, advances in external defibrillation techniques, and development of other relevant noninvasive techniques that can be suitably delivered in the pre-hospital settings have improved the skills of the EMS professionals to an astronomical degree in comparison to the earlier times. These have improved the success rates of pre-hospital
