Question: Information:  - Emergency medical services, also known as ambulance services or paramedic services (abbreviated to the initialism EMS, EMAS, EMARS or SAMU in some countries), are a type of emergency service dedicated to providing out-of-hospital acute medical care, transport to definitive care, and other medical transport to patients with illnesses and injuries which prevent the patient from transporting themselves. Emergency medical services may also be locally known as a paramedic service, a first aid squad, FAST squad, emergency squad, rescue squad, ambulance squad, ambulance service, ambulance corps, or life squad.  - An automated external defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient, and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm.  - The scope of practice describes the procedures, actions, and processes that a healthcare practitioner is permitted to undertake in keeping with the terms of their professional license. The scope of practice is limited to that which the law allows for specific education and experience, and specific demonstrated competency. Each jurisdiction has laws, licensing bodies, and regulations that describe requirements for education and training, and define scope of practice.  - Agonal respiration, gasping respiration or agonal breathing is an abnormal pattern of breathing and brainstem reflex characterized by gasping, labored breathing, accompanied by strange vocalizations and myoclonus. Possible causes include cerebral ischemia, extreme hypoxia or even anoxia. Agonal breathing is an extremely serious medical sign requiring immediate medical attention, as the condition generally progresses to complete apnea and heralds death. The duration of agonal respiration can be as brief as two breaths or last up to several hours. The term is sometimes (inaccurately) used to refer to labored, gasping breathing patterns accompanying organ failure (e.g. liver failure and renal failure), SIRS, septic shock, and metabolic acidosis (see Kussmaul breathing, or in general any labored breathing, including Biot's respirations and ataxic respirations). Correct usage would restrict the term to the last breaths before death.  - The International Liaison Committee on Resuscitation (ILCOR) was formed in 1992 to provide an opportunity for the major organizations in resuscitation to work together on CPR (Cardiopulmonary Resuscitation) and ECC (Emergency Cardiovascular Care) protocols. The name was chosen in 1996 to be a deliberate play on words relating to the treatment of sick hearts - ""ill cor"" ("cor" is latin for "heart").  - First aid is the assistance given to any person suffering a sudden illness or injury, with care provided to preserve life, prevent the condition from worsening, and/or promote recovery. It includes initial intervention in a serious condition prior to professional medical help being available, such as performing CPR while awaiting an ambulance, as well as the complete treatment of minor conditions, such as applying a plaster to a cut. First aid is generally performed by the layperson, with many people trained in providing basic levels of first aid, and others willing to do so from acquired knowledge. Mental health first aid is an extension of the concept of first aid to cover mental health.  - Mental Health First Aid is a training program that teaches members of the public how to help a person developing a mental health problem (including a substance use problem), experiencing a worsening of an existing mental health problem or in a mental health crisis. Like traditional first aid, Mental Health First Aid does not teach people to treat or diagnose mental health or substance use conditions. Instead, the training teaches people how to offer initial support until appropriate professional help is received or until the crisis resolves. While first aid for physical health crises is a familiar notion in developed countries, conventional first aid training has not generally incorporated mental health problems.  - Cardiopulmonary resuscitation, commonly known as CPR, is an emergency procedure that combines chest compression often with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It is indicated in those who are unresponsive with no breathing or abnormal breathing, for example, agonal respirations.  According to the International Liaison Committee on Resuscitation guidelines, CPR involves chest compressions for adults between and deep and at a rate of at least 100 to 120 per minute. The rescuer may also provide artificial ventilation by either exhaling air into the subject's mouth or nose (mouth-to-mouth resuscitation) or using a device that pushes air into the subject's lungs (mechanical ventilation). Current recommendations place emphasis on high-quality chest compressions over artificial ventilation; a simplified CPR method involving chest compressions only is recommended for untrained rescuers. In children only doing compressions may result in worse outcomes.  - Mouth-to-mouth resuscitation, a form of artificial ventilation, is the act of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body, where a rescuer presses his or her mouth against that of the victim and blows air into the person's lungs. Assistance takes many forms, but generally entails providing air for a person who is not breathing or is not making sufficient respiratory effort on his/her own. It is used on a patient with a beating heart or as part of cardiopulmonary resuscitation (CPR) to achieve the internal respiration).   - A patient is any recipient of health care services. The patient is most often ill or injured and in need of treatment by a advanced practice registered nurse, physiotherapist, physician, physician assistant, psychologist, podiatrist, veterinarian, or other health care provider.  - Cardiac arrest is a sudden stop in effective blood flow due to the failure of the heart to contract effectively. Symptoms include loss of consciousness and abnormal or absent breathing. Some people may have chest pain, shortness of breath, or nausea before this occurs. If not treated within minutes, death usually occurs. The most common cause of cardiac arrest is coronary artery disease. Less common causes include major blood loss, lack of oxygen, very low potassium, heart failure, and intense physical exercise. A number of inherited disorders may also increase the risk including long QT syndrome. The initial heart rhythm is most often ventricular fibrillation. The diagnosis is confirmed by finding no pulse. While a cardiac arrest may be caused by heart attack or heart failure these are not the same. Prevention includes not smoking, physical activity, and maintaining a healthy weight. Treatment for cardiac arrest is immediate cardiopulmonary resuscitation (CPR) and, if a shockable rhythm is present, defibrillation. Among those who survive targeted temperature management may improve outcomes. An implantable cardiac defibrillator may be placed to reduce the chance of death from recurrence. In the United States, cardiac arrest outside of hospital occurs in about 13 per 10,000 people per year (326,000 cases). In hospital cardiac arrest occurs in an additional 209,000 Cardiac arrest becomes more common with age. It affects males more often than females. The percentage of people who survive with treatment is about 8%. Many who survive have significant disability. Many U.S. television shows, however, have portrayed unrealistically high survival rates of 67%.  - Artificial ventilation, also called artificial respiration is any means of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body by pulmonary ventilation, external respiration, and internal respiration. It may take the form of manually providing air for a person who is not breathing or is not making sufficient respiratory effort on his/her own, or it may be mechanical ventilation involving the use of a mechanical ventilator to move air in and out of the lungs when an individual is unable to breathe on their own, for example during surgery with general anesthesia or when an individual is in a coma.  - Ventricular tachycardia (V-tach or VT) is a type of regular and fast heart rate that arises from improper electrical activity in the ventricles of the heart. Although a few seconds may not result in problems, longer periods are dangerous. Short periods may occur without symptoms or present with lightheadedness, palpitations, or chest pain. Ventricular tachycardia may result in cardiac arrest and turn into ventricular fibrillation. Ventricular tachycardia is found initially in about 7% of people in cardiac arrest. Ventricular tachycardia can occur due to coronary heart disease, aortic stenosis, cardiomyopathy, electrolyte problems, or a heart attack. Diagnosis is by an electrocardiogram (ECG) showing a rate of greater than 120 bpm and at least three wide QRS complexes in a row. It is classified as non-sustained versus sustained based on whether or not it lasts less than or more than 30 seconds. The term "ventricular tachycardias" refers to the group of irregular heartbeats that includes ventricular tachycardia, ventricular fibrillation, and torsades de pointes. In those who have a normal blood pressure and strong pulse, the antiarrhythmic medication procainamide may be used. Otherwise immediate cardioversion is recommended. In those in cardiac arrest due to ventricular tachycardia cardiopulmonary resuscitation (CPR) and defibrillation is recommended. Biphasic defibrillation may be better than monophasic. While waiting for a defibrillator, a precordial thump may be attempted in those on a heart monitor who are seen to go into an unstable ventricular tachycardia. In those with cardiac arrest due to ventricular tachycardia survival is about 45%. An implantable cardiac defibrillator or medications such as calcium channel blockers or amiodarone may be used to prevent recurrence. Signs and symptoms. While a few seconds may not result in problems longer periods are dangerous. Short periods may occur without symptoms or present with lightheadedness, palpitations, or chest pain. Ventricular tachycardia may result in...  - Emergency Medical Technician (EMT) and ambulance technician are terms used in some countries to denote a health care provider of emergency medical services. EMTs are clinicians, trained to respond quickly to emergency situations regarding medical issues, traumatic injuries and accident scenes. Under the British system and those that are influenced by it, they are referred to as ambulance technicians (often shortened to techs), while in the American system and its influenced countries, they are referred to as emergency medical technicians.  - Emergency medical responders are people who are specially trained to provide out-of-hospital care in medical emergencies. There are many different types of emergency medical responders, each with different levels of training, ranging from first aid and basic life support. Emergency Medical Responders have a very limited scope of practice and have the least amount of comprehensive education, clinical experience or clinical skills of EMS personnel. The Emergency Medical Responder (EMR) is not meant to replace the roles of Emergency Medical Technicians, Emergency Medical Technologists or Paramedics and their wide range of specialities. Emergency Medical Responders typically assist in rural regions providing basic life support where pre-hospital health professionals are not available due to limited resources or infrastructure.  - A firefighter (historically fireman) is a rescuer extensively trained in firefighting, primarily to extinguish hazardous fires that threaten property and civilian or natural populations, and to rescue people from dangerous situations, like collapsed or burning buildings or crashed vehicles. In some areas, they are also trained in Emergency Medical Services (EMS) and operate ambulances in addition to being a firefighter.  - For the more current term , see Emergency medical responder A certified first responder ( Also called an Emergency Medical Responder , Medical First Responder , or First Responder ) is a person who has completed a course and received certification in providing pre-hospital care for medical emergencies . Certified individuals should have received much more instruction than someone who is trained in basic first aid and cardiopulmonary resuscitation ( CPR ) but they are not necessarily a substitute for more advanced emergency medical care rendered by emergency medical technicians ( EMTs ) and paramedics . First responders typically provide advanced first aid level care , CPR , and automated external defibrillator ( AED ) usage . The term `` certified first responder '' is not to be confused with `` first responder '' , which is a generic term referring to the first medically trained responder to arrive on scene ( police , fire , EMS ) . Many police officers and firefighters must be at least certified first responders . This is the required level of training . Some police officers and firefighters obtain more training to become emergency medical technicians or paramedics .    After reading the paragraphs above, we are interested in knowing the entity with which 'certified first responder' exhibits the relationship of 'field of this profession'. Find the answer from the choices below.  Choices: - education  - emergency service  - exchange  - go  - health care  - law  - management  - mental health  - organ  - play  - television  - training
