Thus, when the words ‘epi’ and ‘dermis’ are added together they form the word ‘epidermis’, translating as the outer layer of the skin. 1 shows a basic representation of the structure of the skin. 14 15 Hair root Sebaceous gland Fig. 1 Diagram of the structure of the skin.
A susceptible individual may develop a pressure ulcer for a variety of reasons, for example, enforced bed rest, loss of sensation. Damage may result from high pressures over a short period of time or from lower pressures over a longer period of time. Bridel (1993) argues that once the critical values for pressure and time have been reached, tissue damage will proceed at a similar rate regardless of the degree of pressure being exerted. 1. 1 Extrinsic factors. The three factors in this area may be defined as: • Pressure: the force applied vertically to a surface • Shear: the force that is applied tangentially or in parallel (Bliss, 1993) • Friction: resistance met by the body moving over another surface Shearing forces may occur when an individual slides down the bed or chair.
