Injuries

A medical emergency is an injury or illness that is acute and poses an immediate risk to a person's life or long term health. These emergencies may require assistance from another person, who should ideally be suitably qualified to do so, although some of these emergencies can be dealt with by the victim themselves.]citation needed[ 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 to Emergency Medical Technicians and emergency physicians.

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 of medical care (for instance, in the street or alone at home).

First aid is the provision of initial care for an illness or injury. It is usually performed by non-expert, but trained personnel to a sick or injured person until definitive medical treatment can be accessed. Certain self-limiting illnesses or minor injuries may not require further medical care past the first aid intervention. It generally consists of a series of simple and in some cases, potentially life-saving techniques that an individual can be trained to perform with minimal equipment.

While first aid can also be performed on all animals, the term generally refers to care of human patients.

Exit Wounds is a 2001 action film based on the book of the same name by John Westermann. The book takes place on Long Island, while the film is set in Detroit. The film was directed by Andrzej Bartkowiak, and stars Steven Seagal as an urban detective notorious for pushing the limits of the law in his quest for justice. Although the story is set in Detroit, many goofs in production make it apparent that most of the movie was filmed in Toronto, Ontario; Hamilton, Ontario and Calgary, Alberta.

It is the second of three subsequent films directed by Andrzej Bartkowiak and produced by Joel Silver (preceded by Romeo Must Die the year before and followed by Cradle 2 the Grave two years later) that focus on martial-arts based action in an urban setting with a hip-hop heavy soundtrack and featuring many of the same cast (such as DMX and Anthony Anderson)

Wound

Penetrating trauma is an injury that occurs when an object pierces the skin and enters a tissue of the body, creating an open wound. In blunt, or non-penetrating trauma, there may be an impact, but the skin is not necessarily broken. The penetrating object may remain in the tissues, come back out the way it entered, or pass through the tissues and exit from another area. An injury in which an object enters the body or a structure and passes all the way through is called a perforating injury, while penetrating trauma implies that the object does not pass through. Perforating trauma is associated with an entrance wound and an often larger exit wound.

Penetrating trauma can be caused by a foreign object or by fragments of a broken bone. Usually occurring in violent crime or armed combat, penetrating injuries are commonly caused by gunshots and stabbings.

The single-bullet theory (or Magic Bullet Theory, as it is commonly called by its critics) was introduced by the Warren Commission in its investigation of the assassination of President John F. Kennedy to explain what happened to the bullet which struck Kennedy in the back and exited through his throat. Given the lack of damage to the presidential limousine consistent with it having been struck by a high-velocity bullet and the fact that Texas Governor John Connally was wounded and was seated directly in front of the president, the Commission concluded they were likely struck by the same bullet.

The theory, generally credited to Warren Commission staffer Arlen Specter (later a United States Senator from Pennsylvania), posits that a single bullet, known as "Warren Commission Exhibit 399" (also known as "CE 399"), caused all the wounds to the governor and the non-fatal wounds to the president (seven entry/exit wounds in total).

Medicine

Emergency medicine is a medical specialty involving care for patients with acute illnesses or injuries which require immediate medical attention. While not usually providing long-term or continuing care, emergency medicine physicians diagnose a variety of illnesses and undertake acute interventions to resuscitate and stabilize patients. Emergency medicine physicians practice in hospital emergency departments, pre-hospital settings via emergency medical services, other locations where initial medical treatment of illness takes place, and recently the intensive-care unit. Just as clinicians operate by immediacy rules under large emergency systems, emergency practitioners aim to diagnose emergent conditions and stabilize the patient for definitive care.

Physicians specializing in emergency medicine in the US and Canada can enter fellowships to receive credentials in subspecialties. These are palliative medicine, critical care medicine, medical toxicology, wilderness medicine, pediatric emergency medicine, sports medicine, emergency medical services, and undersea and hyperbaric medicine.
