Overlay: An additional support surface designed to be placed directly on top of an exiting surface.

Pad: A cushion like mass of soft material used for comfort, protection or positioning.

Pressure Mapping: A measurement of interface pressure, that is, the pressure between the body and the support surface.

Pressure Redistribution: The ability of a support surface to distribute load over the contact areas of the human body.

Pressure Ulcer: Also known as Bedsores, more properly known as pressure ulcers or decubitus ulcers, are lesions caused by many factors such as: unrelieved pressure; friction; humidity; shearing forces; temperature; age; continence and medication; to any part of the body, especially portions over bony or cartilaginous areas.

Pressure: The force per unit area exerted perpendicular to the plane of interest.

Proposition 65: See Below.

Reactive Hyperemia: is the transient increase in organ blood flow that occurs following a brief period of ischemia . Following Ischemia there will be a shortage of oxygen and a build-up of metabolic waste.

Reactive support surface: A powered or non-powered support surface with the capability to change its load distribution properties only in response to applied load.

SCT: (Surface Cut Technology) Blue Chip’s foam cutting technology that provides the unique pressure redistribution qualities of Blue Chip’s Prevent Series.

What is Reactive Hyperemia and Why it's Important for Wound Care
Reactive hyperemia is the body’s response to periods of inadequate blood supply to a tissue or organ such as the skin. This phenomenon in wound care, refers to increase of blood circulation in the small arteries and capillaries after the skin has experienced a temporary obstruction in blood flow. Obstruction in blood supply to the […]
