What Causes Bed Sores?

Bed sores, also known as pressure ulcers or pressure injuries, are localized injuries to the skin and underlying tissue usually occurring over a bony prominence. They are most commonly seen in individuals who are bedridden or confined to a wheelchair for prolonged periods. The development of bed sores can have a significant impact on a person's health and quality of life.

Pressure Ulcer Stages

Bed sores progress through a series of stages, each characterized by more severe tissue damage:

Stage 1

• Non-blanchable erythema of intact skin. This means the skin is red and doesn't turn white when you press on it.

Stage 2

• Partial-thickness skin loss involving the epidermis and/or dermis. This may appear as a blister or abrasion.

Stage 3

• Full-thickness skin loss extending into the subcutaneous tissue.
• This stage involves deeper tissue damage and may appear as a crater.

Stage 4

• Full-thickness skin and tissue loss with exposed bone, tendon, or muscle.

What Causes Bed Sores

The primary cause of bed sores is prolonged pressure on the skin. When pressure is applied to an area for an extended time, it restricts blood flow to the tissues underneath. This can lead to cell death and the development of a sore.

Risk Factors

Various factors can increase a person's risk of developing bed sores, including:

• Immobility: Individuals who are unable to move easily or change positions frequently are at a higher risk.
• Poor nutrition: A lack of essential nutrients can weaken the skin and make it more vulnerable to pressure damage.
• Incontinence: Moisture from urine or feces can irritate the skin and increase the risk of infection.
• Diabetes:

Diabetes can affect blood circulation and delay wound healing.

• Advanced age: Older adults are more prone to pressure ulcers because their skin becomes thinner and less elastic.

Pressure Points

Certain areas of the body are more susceptible to bed sores due to their prominence and reduced blood flow. These pressure points include:

• Heels
• Sacrum (lower back)
• Hip bones
• Shoulder blades
• Elbows
• EARS

Preventing Bed Sores

Effective prevention strategies are crucial to minimizing the risk of bed sores:

Regular repositioning

Encourage frequent repositioning every 2 hours for individuals who are bedridden. This helps redistribute pressure and improve blood flow.

Protective surfaces

Use pressure-relieving mattresses, cushions, or pads to reduce the amount of pressure on bony areas.

Skin care

Keep the skin clean and dry to prevent irritation and moisture buildup.

Proper nutrition

Ensure that individuals at risk receive adequate nutrition to support healthy skin and wound healing.

Addressing medical conditions

Manage underlying medical conditions, such as diabetes, that can contribute to pressure ulcer development.
