Questions and Answers
How do conditions like paralysis and stroke affect sensation and healing in individuals?
They cause loss of sensation in body areas, impairing the ability to respond to trauma and heal wounds.
What impact does diminished pain perception have on older adults regarding skin integrity?
It increases the risk for impaired skin integrity due to a reduction in the sensation of pressure and light touch.
Explain how elevated body temperature can contribute to the development of pressure injuries.
It increases metabolic rate and the cells' need for oxygen, heightening the risk of tissue damage under pressure.

Study Notes
Diminished Sensation
- Conditions like paralysis, stroke, or other neurological diseases can lead to loss of sensation in a body area
- Loss of sensation hinders an individual's ability to respond to trauma, extreme temperatures, and tingling sensations indicating circulatory problems
- Diminished sensation also hampers the body's capacity to recognize and heal wounds.
- Older adults face a higher risk of skin damage due to reduced pain perception caused by decreased cutaneous end organs responsible for pressure and touch sensation
Excessive Body Heat
- Elevated body temperature increases the metabolic rate, thereby demanding more oxygen from cells
- This heightened oxygen need is particularly pronounced in areas under pressure where oxygen deficiency already exists
- Severe infections accompanied by high temperatures can negatively impact the body's ability to manage the effects of tissue compression.
### Aging and Skin Integrity
- The aging process weakens the skin and its supporting structures, increasing risk of impaired skin integrity.
- Skin changes with age include loss of lean body mass, thinner epidermis, reduced skin strength and elasticity, and decreased blood flow due to aging blood vessels.
- Reduced oil production by sebaceous glands contributes to skin dryness and increases skin impairment risk in older adults.
### Chronic Medical Conditions and Skin Integrity
- Chronic conditions like diabetes and cardiovascular disease increase the risk of skin breakdown and delayed healing.
- These conditions can compromise oxygen delivery to tissues, hindering wound healing and increasing the risk of pressure injuries.
Other Factors Contributing to Pressure Injuries
- Poor lifting and transferring techniques can contribute to pressure injuries.
- Incorrect positioning and hard support surfaces increase the risk of pressure injuries.
- Improper use of pressure-relieving devices can also lead to pressure injuries.
