Chapter 19 Terms Flashcards
Adult respiratory distress syndrome (ARDS)
A lung condition in which trauma to the lungs leads to inflammation, accumulation of fluid in the alveolar air sacs, low blood oxygen and respiratory distress.
Arteries
Large blood vessels that carry oxygen-rich blood from the heart to all parts of the body, except for the pulmonary arteries, which carry oxygen-poor blood from the heart to the lungs.
Bandage
Material used to wrap or cover a part of the body.
Commonly used to hold a dressing or splint in place.
Bandage compress
A thick gauze dressing attached to a gauze bandage.
Bleeding
The loss of blood from arteries, veins or capillaries.
Blood volume
The total amount of blood circulating within the body.
Capillaries
Tiny blood vessels linking arteries and veins that transfer oxygen and other nutrients from the blood to all body cells and remove waste products.
CLotting
The process by which blood thickens at a wound site to seal an opening in a blood vessel and stop bleeding.
Contusion
An injury to the soft tissues that results in blood vessel damage - usually to capillaries - and leakage of blood into the surrounding tissues.
Caused when blood vessels are damaged or broken as a result of a blow to the skin, resulting in swelling and a reddish-purple discoloration on the skin.
Commonly referred to as a bruise.
Direct pressure
Pressure applied to a wound to control bleeding.
Dressing
A pad placed directly over a wound to absorb blood and other bodily fluids and to prevent infection.
Elastic bandage
A bandage designed to keep continuous pressure on a body part.
Also called an elastic wrap.
External bleeding
Bleeding on the outside of the body, often visible bleeding.
Golden hour
A term sometimes used to describe the first hour after a life-threatening traumatic injury.
Providing early interventions and advanced medical care during this time frame can result in the best chance of survival.
Head-on collision
A collision in which a vehicle hits an object, such as a tree or other vehicle, straight on.
Hemorrhage
The loss of large amount of blood in a short time or when there is continuous bleeding.
Hemostatic agent
A method of external hemorrhage control that used a substance that absorbs or absorbs the moisture from blood and speeds the process of coagulation and clot formation to achieve homeostasis.
Control of bleeding.
Internal bleeding
Bleeding inside the body.
Occlusive dressing
A special type of dressing that does not allow air or fluid to pass through.
Perfusion
The circulation of blood through the body or through a particular body part for the purpose of exchanging oxygen and nutrients with carbon dioxide and other wastes.
Pressure bandage
A bandage applied snugly to create pressure on a wound, to aid in controlling of bleeding.
Pressure points
Sites on the body where pressure can be applied to major arteries to slow the flow of blood to a body part.
Roller bandage
A bandage made of gauze or gauze-like material that is wrapped around a body part, over a dressing, using overlapping turns until the dressing is covered.
Rollover
A collision in which the vehicle rolls over.
