Study Notes
Skin Color and Texture
- Cyanosis, a blue discoloration of the skin and nail bed, indicates a lack of oxygen and excessive carbon dioxide in superficial blood vessels.
- Pallor, a pale skin tone, is associated with decreased blood flow or blood hemoglobin, and can be seen in conditions such as peripheral vasoconstriction, shock, internal bleeding, and anemia.
- Erythema, a localized redness, is a sign of increased blood flow and inflammation.
- Generalized redness can be caused by fever, sunburn, or carbon monoxide poisoning.
- Yellow skin tone can be due to increased carotene intake or liver disease.
- Brown, highly pigmented, hairy areas may overlay bony defects such as spina bifida.
Skin Lesions and Wounds
- Open wounds should be measured and diagrammed in patient records.
- New scars are red, while older scars are white in color.
- Skin tissue thickenings, such as calluses, can indicate chronic overloading and stress.
- Thin, glossy skin with decreased elasticity and hair loss is often associated with peripheral nerve lesions or neurovascular disorders.
Test your knowledge on skin color and texture abnormalities like cyanosis, pallor, erythema, and generalized redness which indicate various underlying health conditions related to blood flow, oxygen levels, and inflammation.
