Nurses play a vital role in provision of health care facilities to the patients. Nurses are the competent professionals having the aptitude to meet the patient’s needs. The nurses are responsible for the provision of medication to the patient in accordance with the prescription by the doctors. They are responsible to conduct the regular checkups including monitoring of pulse rate, blood pressure and body temperature. They are accountable for diverse activities like collecting specimen for various medical tests, maintaining medical records of the patients and assisting the doctors in treating patients. Nurses have a significant role in provision of medical assistance to the patients in cardiac emergencies as they are the primary witnesses of distressful condition of the patients. The CPR certified nurses are fully competent to respond the emergencies in a seamless manner and are capable to provide preliminary treatment to the patient suffering from cardiac attacks. The certified nurses are capable to recognize the need for CPR and are trained to demonstrate appropriate steps of CPR according to the responsiveness of the patients. Since cardiac attacks are of abrupt nature accompanied by unfavorable factors so the certified nurses are trained to deal with the unanticipated outcomes during resuscitation process. The certified nurses are eligible for prompt intrusion in the emergencies after the rapid assessment of the patient. Since resuscitation for cardiac arrest is always time restricted it demands high vigilance and accuracy from the responder. The certified nurses recognize the complexity of the situation and are able to exhibit rapid and immediate actions for the resuscitation of the patient. Slight deferral can be detrimental for the survival of the patient. Survival of suffer is directly proportional to accessibility of immediate and efficient CPR, the initial four minutes are considered decisive for the recuperation of the patient. The certified nurses follow the systematic procedures and guidelines to evade complication during resuscitation. An ignorant rescuer would be indecisive for the initiation of impulse resuscitation. The trained nurses understand the nature of emergency and are able to make appropriate and abrupt decisions during such crucial time. The nurses are authorized to initiate resuscitation without the explicit commands from the doctors but they seek immediate assistance from their supervisors in case of adverse condition of the patient. They collaborate with their supervisors and doctors to achieve optimal recovery. After initial assessment of the patient the nurses follow series of successive steps for resuscitation which include opening airway, breathing and compressions. Generally oral resuscitation and external resuscitation techniques are widely adopted by the nurses for the reinstating cardiac function and blood flow.
