When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Chronic Wound (Pressure Ulcer).
Pressure ulcers develop when sustained pressure cuts off blood flow to the skin and underlying tissues.
Pressure ulcers develop when sustained pressure cuts off blood flow to the skin and underlying tissues. When you sit or lie in one position, your body weight creates pressure between your bones and the surface beneath you. Normally, you shift positions frequently without thinking about it, allowing blood to flow back into compressed areas. However, when pressure continues for too long, cells begin to die from lack of oxygen and nutrients, leading to tissue breakdown and wound formation.
Three main forces contribute to pressure ulcer development: direct pressure, friction, and shearing.
Three main forces contribute to pressure ulcer development: direct pressure, friction, and shearing. Direct pressure occurs when body weight presses against a surface for extended periods. Friction happens when skin rubs against bedding, clothing, or other surfaces during movement. Shearing forces develop when the skin surface stays in place while deeper tissues slide in different directions, such as when sliding down in bed or a wheelchair.
The process typically begins with damage to small blood vessels in the skin and deeper tissues.
The process typically begins with damage to small blood vessels in the skin and deeper tissues. As circulation decreases, the affected area may first appear red or discolored. Without relief from pressure, the skin breaks down further, forming blisters, open sores, or deep wounds. Areas with thin skin covering bony prominences like the tailbone, heels, and hips face the greatest risk because there's less cushioning to distribute pressure.
Risk Factors
- Limited mobility or being bedridden for extended periods
- Advanced age, especially over 70 years old
- Poor nutrition or dehydration
- Medical conditions affecting blood flow like diabetes or vascular disease
- Incontinence leading to prolonged skin moisture exposure
- Reduced sensation or inability to feel pressure or pain
- Previous history of pressure ulcers
- Smoking, which reduces blood flow to tissues
- Low body weight or muscle wasting
- Certain medications that affect circulation or healing
Diagnosis
How healthcare professionals diagnose Chronic Wound (Pressure Ulcer):
- 1
Healthcare providers typically diagnose pressure ulcers through visual examination and patient history.
Healthcare providers typically diagnose pressure ulcers through visual examination and patient history. During the assessment, your doctor will carefully inspect your skin, paying special attention to areas over bony prominences where pressure ulcers commonly develop. They'll look for changes in skin color, temperature, texture, and any signs of breakdown or open wounds. The examination includes checking areas you might not easily see yourself, such as your back, buttocks, and heels.

Doctors use a staging system to classify pressure ulcer severity and guide treatment decisions.
Doctors use a staging system to classify pressure ulcer severity and guide treatment decisions. Stage 1 ulcers show red or discolored skin that doesn't blanch when pressed. Stage 2 involves partial skin loss with blistering or shallow open wounds. Stage 3 extends through the full skin thickness into underlying fat tissue. Stage 4 reaches deep tissues including muscle, bone, or joints. Unstageable ulcers have dead tissue covering the wound, making depth assessment impossible until cleaning occurs.

Additional tests may include wound cultures if infection is suspected, blood tests to check nutritional status and overall health, and sometimes imaging studies like X-rays or MRI scans for deep wounds.
Additional tests may include wound cultures if infection is suspected, blood tests to check nutritional status and overall health, and sometimes imaging studies like X-rays or MRI scans for deep wounds. Your healthcare team will also assess your risk factors, mobility level, nutritional status, and ability to participate in prevention strategies. This comprehensive evaluation helps create an individualized treatment and prevention plan tailored to your specific needs and circumstances.
Complications
- Infection represents the most serious immediate complication of pressure ulcers.
- Bacteria can easily enter open wounds, leading to local skin infections, deeper tissue infections, or life-threatening bloodstream infections (sepsis).
- Signs of infection include increased pain, redness spreading beyond the wound edges, warmth, swelling, fever, and foul-smelling drainage.
- Some infections can progress to involve underlying bone (osteomyelitis), which is particularly difficult to treat and may require months of antibiotic therapy.
- Long-term complications can significantly impact quality of life and independence.
- Large or deep pressure ulcers may require extensive surgical reconstruction, prolonged hospitalization, or permanent changes in mobility and function.
- Some ulcers become chronic wounds that never fully heal, requiring ongoing medical care and limiting daily activities.
- In severe cases, complications from pressure ulcers contribute to approximately 60,000 deaths annually in the United States, often due to overwhelming infections in already vulnerable patients.
Prevention
- The most effective prevention strategy involves regular pressure relief through frequent position changes.
- People in bed should change positions at least every two hours, while wheelchair users need to shift weight every 15-30 minutes or have others help reposition them hourly.
- Specialized equipment like pressure-redistributing mattresses, cushions, and heel protectors can significantly reduce pressure on vulnerable areas.
- Daily skin inspection is equally important, especially for people with limited sensation or mobility.
- Caregivers and patients should check for early warning signs like redness, warmth, or skin texture changes, particularly over bony prominences.
- Keeping skin clean and dry while avoiding harsh soaps or excessive moisture helps maintain skin integrity.
- Proper nutrition with adequate protein, vitamins, and hydration supports overall skin health and healing capacity.
- For high-risk individuals, healthcare providers may recommend formal risk assessment tools and structured prevention protocols.
- These might include specialized positioning schedules, skin care routines, and regular monitoring by trained professionals.
- While not all pressure ulcers can be prevented, especially in critically ill patients, consistent application of prevention strategies can reduce risk by up to 90 percent in many cases.
Treatment approaches vary significantly based on the ulcer's stage, location, and the patient's overall health.
Treatment approaches vary significantly based on the ulcer's stage, location, and the patient's overall health. For early-stage pressure ulcers, the primary focus involves relieving pressure through frequent position changes, specialized cushions, and pressure-redistributing mattresses. Healthcare providers clean the wound regularly and apply appropriate dressings to maintain optimal moisture levels while protecting the area from further damage. Simple treatments like hydrocolloid or foam dressings often work well for shallow wounds.
Advanced pressure ulcers require more intensive interventions.
Advanced pressure ulcers require more intensive interventions. Healthcare teams may use specialized wound care products including alginate dressings, negative pressure wound therapy, or bioengineered skin substitutes. Debridement - the removal of dead or infected tissue - becomes necessary for deeper wounds to promote healing. This can be done surgically, with special enzymes, or through other methods depending on the wound characteristics and patient factors.
Nutritional support plays a critical role in healing, with many patients requiring increased protein, vitamins, and calories to support tissue repair.
Nutritional support plays a critical role in healing, with many patients requiring increased protein, vitamins, and calories to support tissue repair. Healthcare providers often recommend nutritional supplements or work with dietitians to optimize healing potential. Pain management is equally important, as pressure ulcers can be extremely painful and interfere with necessary position changes and daily activities.
Severe or non-healing ulcers may require surgical intervention, including flap reconstruction where healthy tissue is moved to cover the wound.
Severe or non-healing ulcers may require surgical intervention, including flap reconstruction where healthy tissue is moved to cover the wound. New treatments showing promise include stem cell therapy, growth factors, and advanced biologics that accelerate healing. Throughout treatment, infection prevention and management remain top priorities, as infected pressure ulcers can lead to serious complications including bloodstream infections.
Living With Chronic Wound (Pressure Ulcer)
Managing life with pressure ulcers requires significant adjustments to daily routines and activities. Healing can take weeks to months, during which maintaining proper wound care becomes a daily priority. This includes regular dressing changes, careful positioning, and constant vigilance for signs of infection or worsening. Many people find it helpful to create schedules for position changes and wound care to ensure consistency.
