Emergency medical technician in the context of "Paramedics"

A paramedic is a healthcare professional trained in the medical model, whose main role has historically been to respond to emergency calls for medical help outside of a hospital. Paramedics work as part of the emergency medical services (EMS), most often in ambulances. They also have roles in emergency medicine, primary care, transfer medicine and remote/offshore medicine. The scope of practice of a paramedic varies between countries, but generally includes autonomous decision making around the emergency care of patients.

Not all ambulance personnel are paramedics, although the term is sometimes used informally to refer to any ambulance personnel. In some English-speaking countries, there is an official distinction between paramedics and emergency medical technicians (or emergency care assistants), in which paramedics have additional educational requirements and scope of practice.

A medical emergency is an acute injury or illness that poses an immediate risk to a person's life or long-term health, sometimes referred to as a situation risking "life or limb". These emergencies may require assistance from another, qualified person, as some of these emergencies, such as cardiovascular (heart), respiratory, and gastrointestinal cannot be dealt with by the victim themselves. Dependent on the severity of the emergency, and the quality of any treatment given, it may require the involvement of multiple levels of care, from first aiders through emergency medical technicians, paramedics, emergency physicians and anesthesiologists.

Any response to an emergency medical situation will depend strongly on the situation, the patient involved, and availability of resources to help them. It will also vary depending on whether the emergency occurs whilst in hospital under medical care, or outside medical care (for instance, in the street or alone at home).

An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath.

While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency.The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management.

A first responder is a person with specialized training who is among the first to arrive and provide assistance or incident resolution at the scene of an emergency. First responders typically include:

• law enforcement officers (commonly known as police officers),
• emergency medical services members (such as EMTs or paramedics), and
• fire service members (such as firefighters, search and rescue members, technical/heavy rescue members, etc.)

In some jurisdictions, emergency department personnel, such as doctors and nurses, are also required to respond to disasters and critical situations, designating them first responders; in other jurisdictions, military and security forces may also be authorized to act as first responders.

Cosmetology (from Greek κοσμητικός, kosmētikos, "beautifying"; and -λογία, -logia) is the study and application of beauty treatment. Branches of specialty include hairstyling, skin care, cosmetics, manicures/pedicures, non-permanent hair removal such as waxing and sugaring, and permanent hair removal processes such as electrology and intense pulsed light (IPL).

In the United States as of 2008, an occupational license is required in all states to be a cosmetologist, with the average cost of a certificate from a for-profit school being $17,000 and 1,500 required hours (ten times the hours required for an EMT) with cosmetologists making a median wage of $25,000.

Pre-hospital emergency medicine (abbreviated PHEM), also referred to as pre-hospital care, immediate care, or emergency medical services medicine (abbreviated EMS medicine), is a medical subspecialty which focuses on caring for seriously ill or injured patients before they reach hospital, and during emergency transfer to hospital or between hospitals. It may be practised by physicians from various backgrounds such as anaesthesiology, emergency medicine, intensive care medicine and acute medicine, after they have completed initial training in their base specialty.

Doctors practising PHEM are usually well-integrated with local emergency medical services, and are dispatched together with emergency medical technicians or paramedics where potentially life-threatening trauma or illness is suspected that may benefit from immediate specialist medical treatment. This may involve travelling by car or air ambulance to the site.

Life support comprises the treatments and techniques performed in an emergency in order to support life after the failure of one or more vital organs. Healthcare providers and emergency medical technicians are generally certified to perform basic and advanced life-support procedures; however, basic life support is sometimes provided at the scene of an emergency by family members or bystanders before emergency services arrive. In the case of cardiac injuries, cardiopulmonary resuscitation is initiated by bystanders or family members 25% of the time. Basic life-support techniques, such as performing CPR on a victim of cardiac arrest, can double or even triple that patient's chance of survival. Other types of basic life support include relief from choking (which can be done by using the Heimlich maneuver), staunching of bleeding by direct compression and elevation above the heart (and if necessary, pressure on arterial pressure points and the use of a manufactured or improvised tourniquet), first aid, and the use of an automated external defibrillator.

The purpose of basic life support (abbreviated BLS) is to save lives in a variety of different situations that require immediate attention. These situations can include, but are not limited to, cardiac arrest, stroke, drowning, choking, accidental injuries, violence, severe allergic reactions, burns, hypothermia, birth complications, drug addiction, and alcohol intoxication. The most common emergency that requires BLS is cerebral hypoxia, a shortage of oxygen to the brain due to heart or respiratory failure. A victim of cerebral hypoxia may die within 8–10 minutes without basic life-support procedures. BLS is the lowest level of emergency care, followed by advanced life support and critical care.

An emergency physician is a physician who specializes in emergency medicine. They typically work in the emergency department of a hospital and provide care to patients requiring urgent medical attention. Their scope of practice includes advanced cardiac life support (or advanced life support in Europe), resuscitation, trauma care (such as treatment of fractures and soft tissue injuries), and management of other life-threatening conditions. Alternative titles for this role include emergency medicine physician, emergentologist, ER physician, or ER doctor (with ER standing for an emergency room, primarily used in the United States).

In some European countries (e.g. Germany, Belgium, Poland, Austria, Denmark and Sweden), emergency physicians or anaesthetists are also part of the emergency medical service. They are dispatched together with emergency medical technicians and paramedics in cases of potentially life-threatening situations such as serious accident or injury, unconsciousness, heart attack, cardiac arrest, stroke, anaphylaxis, or drug overdose. In the United States, emergency physicians are mostly hospital-based, but also work on air ambulances and mobile intensive care units.
