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.
An elastic bandage is a "stretchable bandage used to create localized pressure". Elastic bandages are commonly used to treat muscle sprains and strains by reducing the flow of blood to a particular area by the application of even stable pressure which can restrict swelling at the place of injury. Elastic bandages are also used to treat bone fractures. Padding is applied to the fractured limb, then a splint (usually plaster) is applied. The elastic bandage is then applied to hold the splint in place and to protect it. This is a common technique for fractures which may swell, which would cause a cast to function improperly. These types of splints are usually removed after swelling has decreased and then a fiberglass or plaster cast can be applied.
Due to the risk of latex allergies among users, the original composition of elastic bandages has changed. While some bandages are still manufactured with latex, many woven and knitted elastic bandages provide adequate compression without the use of natural rubber or latex. The modern elastic bandage is constructed from cotton, polyester and latex-free elastic yarns. By varying the ratio of cotton, polyester, and the elastic yarns within a bandage, manufacturers are able to offer various grades of compression and durability in their wraps. Often aluminum or stretchable clips are used to fasten the bandage in place once it has been wrapped around the injury. Some elastic bandages even use Velcro closures to secure and stabilize the wrap in place.
Ace Books is the oldest active specialty publisher of science fiction and fantasy books. The American company was founded in New York City in 1952 by Aaron A. Wyn and began as a genre publisher of mysteries and westerns. It soon branched out into other genres, publishing its first science fiction (sf) title in 1953. This was a successful innovation, and science fiction titles outnumbered both mysteries and westerns within a few years. Other genres also made an appearance, including nonfiction, gothic novels, media tie-in novelizations, and romances.
Ace became known for the tête-bêche binding format used for many of its early books, although it did not originate the format. Most of the early titles were published in this "Ace Double" format, and Ace continued to issue books in varied genres, bound tête-bêche, until 1973. These have proved attractive to book collectors, and some rare titles in mint condition command prices up to $1,000.
A stable bandage, or standing bandage/wrap, is a type of wrap used on the lower legs of a horse. A stable bandage runs from just below the knee or hock, to the bottom of the fetlock joint, and protects the cannon bone, tendons of the lower leg, and fetlock joint.
An orthopedic cast, body cast, plaster cast, or surgical cast, is a shell, frequently made from plaster, encasing a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures, most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint.
Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced.
