Wilderness First Responder
Wilderness first responders are individuals who are trained to respond to emergency situations in remote locations. They are part of a wide variety of wilderness medical providers who deal with medical emergencies that occur in wilderness settings. While wilderness first responder can generically refer to anyone providing first response, more typically, this term refers to individuals trained and certified with specific Wilderness First Responder (WFR) certification. History Near the end of the 19th century, volunteer organizations such as St. John Ambulance began teaching the principles of first aid at mining sites and near large railway centers. By the dawn of the 20th century, additional organizations such as the Boy Scouts and the American Red Cross began teaching first aid to lay people. Over the years, these organizations trained hundreds of thousands of people in the elements of providing assistance until definitive care could be arranged. The training in these courses as ...

Wilderness Medicine
Wilderness medicine is a rapidly evolving field and is of increasing importance as more people engage in hiking, climbing, kayaking, and other potentially hazardous activities in the backcountry. The modern definition of wilderness medicine is "medical care delivered in those areas where fixed or transient geographic challenges reduce availability of, or alter requirements for, medical or patient movement resources". A primary focus of the field is the evaluation, prioritization (triage), preliminary treatment of acute injuries or illnesses which occur in those environments and the emergency evacuation of victims. However, back country rescue and wilderness first aid is not the sole activity of wilderness medical professionals, who are also concerned with many additional topics. These include but are not limited to: * Secondary care follow up to first aid in remote settings, such as expeditions * Evaluation of experience and issuance of updated protocols for first response and sec ...

Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Medic
Street medics, or action medics, are volunteers with a minimum of first aid medical training supplemented by specific protest-related training, who attend protests and demonstrations as support or mutual aid roles to provide medical and wellness care. Unlike emergency medical technicians (EMTs) or paramedics, who have undergone education for professional medical care, street medics usually operate under Good Samaritan clauses and use methods learned through specific protest-medicine training programs which individuals are required to undertake in order to be recognized as a trained street medic. Street medics may treat trauma injuries, chemical agent and other crowd control weapon ailments, animal attacks, as well as general care for things like heat stress or cold exposure, epileptic seizures, and general well-being. History Street medics originated in the U.S. during the Civil Rights Movement and anti-war movement in the 1960s. They conceived of medicine as self-defense, an ...

Certified First Responder
A certified 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 ( EMS, police, fire) and medically trained telecommunication operators who provide pre-arrival medical instructions as trained Emergency Medical Dispatchers (EMD). Many police officers and firefighters are required to receive training as certi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilderness Medical Society
The Wilderness Medical Society was created on 15 February 1983 by three physicians from California, United States — Dr. Paul Auerbach, Dr. Ed Geehr, and Dr. Ken Kizer. It is the largest international non-profit membership organization devoted to addressing wilderness medicine challenges, more specifically defined as "medical care delivered in those areas where fixed or transient geographic challenges reduce availability of, or alter requirements for, medical or patient movement resources". It also publishes '' Wilderness & Environmental Medicine Journal'', ''Wilderness Medicine Magazine'', and Wilderness Medicine Clinical Practice Guidelines. Academy of Wilderness Medicine The academy seeks to provide a system of adult education and certification in a modern and standardised way to provide a set level of knowledge and education for practitioners working in the wilderness arena. The goals of the academy are to: * Professional designation for achievement in Wilderness Medicin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinal Injury
A spinal cord injury (SCI) is damage to the spinal cord that causes temporary or permanent changes in its function. Symptoms may include loss of muscle function, sensation, or autonomic function in the parts of the body served by the spinal cord below the level of the injury. Injury can occur at any level of the spinal cord and can be ''complete'', with a total loss of sensation and muscle function at lower sacral segments, or ''incomplete'', meaning some nervous signals are able to travel past the injured area of the cord up to the Sacral S4-5 spinal cord segments. Depending on the location and severity of damage, the symptoms vary, from numbness to paralysis, including bowel or bladder incontinence. Long term outcomes also range widely, from full recovery to permanent tetraplegia (also called quadriplegia) or paraplegia. Complications can include muscle atrophy, loss of voluntary motor control, spasticity, pressure sores, infections, and breathing problems. In the majority o ...

Dislocations
In materials science, a dislocation or Taylor's dislocation is a linear crystallographic defect or irregularity within a crystal structure that contains an abrupt change in the arrangement of atoms. The movement of dislocations allow atoms to slide over each other at low stress levels and is known as ''glide'' or slip. The crystalline order is restored on either side of a ''glide dislocation'' but the atoms on one side have moved by one position. The crystalline order is not fully restored with a ''partial dislocation''. A dislocation defines the boundary between ''slipped'' and ''unslipped'' regions of material and as a result, must either form a complete loop, intersect other dislocations or defects, or extend to the edges of the crystal. A dislocation can be characterised by the distance and direction of movement it causes to atoms which is defined by the Burgers vector. Plastic deformation of a material occurs by the creation and movement of many dislocations. The number and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprains
A sprain, also known as a torn ligament, is an acute soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movement. Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. An equivalent injury to a muscle or tendon is known as a strain. The majority of sprains are mild, causing minor swelling and bruising that can be resolved with conservative treatment, typically summarized as RICE: rest, ice, compression, elevation. However, severe sprains involve complete tears, ruptures, or fractures, often leading to joint instability, severe pain, and decreased functional ability. These sprains require surgical fixation, prolonged immobilization, and physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fractures
Fracture is the separation of an object or material into two or more pieces under the action of stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops perpendicular to the surface, it is called a normal tensile crack or simply a crack; if a displacement develops tangentially, it is called a shear crack, slip band or dislocation. Brittle fractures occur with no apparent deformation before fracture. Ductile fractures occur after visible deformation. Fracture strength, or breaking strength, is the stress when a specimen fails or fractures. The detailed understanding of how a fracture occurs and develops in materials is the object of fracture mechanics. Strength Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture. This is usually determined for a given specimen by a tensile test, which charts the stress–strain cur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathogen
In biology, a pathogen ( el, πάθος, "suffering", "passion" and , "producer of") in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest ...

Soft Tissue Injury
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. Signs and symptoms Sprains A sprain is a type of acute injury which results from the stretching or tearing of a ligament. Depending on the severity of the sprain, the movement on the joint can be compromised since ligaments aid in the stability and support of joints. Sprains are commonly seen in vulnerable areas such as the wrists, knees and ankles. They can occur from movements such as falling on an outstretched hand or a twisting of the ankle or foot. The severity of a sprain can be classified: * Grade 1: Only some of the fibers in the ligament are torn, and the injured site is moderately painful and swollen. Function in the joint will be unaffected for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
