Pressure Ulcer Treatment: Prevention, Care, and Advanced Therapy

Carter Devis — Thu, 01 Oct 2026 09:26:21 +0000

Pressure ulcers, also called pressure injuries or bed sores, can develop quietly and worsen quickly. They are common in people who spend long periods in a bed or wheelchair, and they can be painful, slow to heal, and at risk of infection. For families and caregivers, knowing the early signs and understanding your pressure ulcer treatment options can make a real difference. This guide covers why pressure ulcers form, how to prevent them, how they are treated, and when advanced therapy may be considered.

At Mel Health Tech in Minneapolis, Minnesota, we work with patients who have chronic and non-healing wounds, including pressure ulcers. This article draws on that experience and on the manufacturer's published information about the device we provide. It is educational and does not replace advice from your own doctor.

What Is a Pressure Ulcer?

A pressure ulcer is an area of damaged skin and underlying tissue caused by prolonged pressure, often combined with friction or shearing forces. When pressure cuts off blood flow to the skin for too long, the tissue starts to break down. Common sites include the tailbone, hips, heels, ankles, and shoulder blades.

People at higher risk include those who have limited mobility, reduced sensation, poor nutrition, incontinence, or conditions such as diabetes and circulation problems.

Stages of Pressure Ulcers

Healthcare providers describe pressure ulcers in stages, which help guide care.

Stage 1. The skin is intact but red, and it does not fade when pressed. The area may feel warm, firm, or painful.

Stage 2. The skin opens, forming a shallow wound or blister.

Stage 3. The wound extends deeper into the tissue beneath the skin.

Stage 4. The wound is very deep and may reach muscle or bone.

Unstageable or deep tissue injury. The depth cannot be seen because of dead tissue in the wound, or the injury lies deeper than the surface suggests.

Only a trained clinician can stage a pressure ulcer accurately, so seek an assessment as soon as you notice a problem.

How to Prevent Pressure Ulcers

Prevention is the best approach, and it is often possible. These steps can lower the risk:

Change position regularly. Follow your care team's advice on how often to turn or shift, as people in bed or in a wheelchair need regular repositioning.
Use pressure-relieving surfaces. Special mattresses, cushions, and heel protectors help spread pressure.
Check the skin daily. Look for redness, warmth, or breaks in the skin, especially over bony areas.
Keep skin clean and dry. Moisture from sweat or incontinence can weaken the skin.
Reduce friction and shear. Lift rather than drag when moving someone, and keep bedding smooth.
Support nutrition and hydration. Protein, vitamins, and fluids help the skin stay healthy and repair itself.

Core Principles of Pressure Ulcer Treatment

Treatment depends on the stage and the person's overall health. A typical plan includes:

Relieving pressure. This is the most important step. Without it, the wound cannot heal. Repositioning schedules and support surfaces are essential.

Wound cleaning and debridement. Removing dead or unhealthy tissue helps new tissue grow. This can be done through several methods, including ultrasound-assisted therapy.

Appropriate dressings. Dressings keep the wound clean and protected, and your provider will choose them based on the wound's condition.

Infection management. Signs of infection need prompt medical attention.

Nutrition and health support. Healing needs energy and nutrients, and other conditions need to be managed.

Regular monitoring. Frequent checks show whether the wound is improving and when the plan needs to change.

Advanced Therapy: Low Frequency Ultrasound

When a pressure ulcer is slow to improve, advanced options may be considered. One of them is low frequency ultrasound therapy, which uses sound waves delivered to the wound bed to support cleaning and preparation for healing. The Arobella Qoustic Wound Therapy System, which Mel Health Tech provides, is an FDA-approved device used in clinics in the United States and in several Eastern European countries.

This therapy is designed for selective debridement, meaning it aims to help remove unhealthy tissue while leaving healthy tissue in place. It is also used as part of a plan to address biofilm, a protective layer of bacteria that can slow healing. Many studies have looked at ultrasound-assisted wound therapy and its effect on the debridement process. Results vary from person to person, and no treatment can promise a specific outcome. It does not replace pressure relief, good nutrition, or regular medical follow-up.

What to Expect During Treatment

If ultrasound therapy is part of the plan, the process generally looks like this:

Assessment. A clinician reviews the wound, medical history, and current care.
Therapy sessions. A trained professional applies the device to the wound. A disposable tubing set is used for each patient for hygiene.
Follow-up. The wound is checked regularly, and the plan is adjusted as needed.

If you have concerns about comfort, talk with your clinician before the first session.

Frequently Asked Questions

Q: What is the first step in pressure ulcer treatment?

A: Relieving pressure on the affected area is the first and most important step. Without it, even the best dressings and therapies are unlikely to work. A clinician will also assess the wound and the cause.

Q:** How long does a pressure ulcer take to heal?**

A: Healing time depends on the stage, size, and location of the ulcer and on the person's overall health. Early-stage ulcers may improve in days to weeks, while deeper ones can take months. Your care team can give you a realistic estimate.

Q: Can pressure ulcers be prevented?

A: In many cases, yes. Regular repositioning, pressure-relieving surfaces, daily skin checks, good hygiene, and proper nutrition all lower the risk.

Q: When should I see a doctor about a pressure ulcer?

A: See a healthcare provider as soon as you notice skin that stays red, an open sore, or signs of infection such as swelling, drainage, a bad smell, or fever. Early care can prevent the wound from worsening.

Q: Can low frequency ultrasound therapy help pressure ulcers?

A: It is used to support wound debridement and prepare the wound bed for healing. Whether it is right for you or your loved one is a decision to make with a healthcare provider after an assessment.

Q: Is ultrasound wound therapy safe?

A: The Arobella Qoustic Wound Therapy System is FDA-approved and is used by trained professionals. It may not be suitable for everyone, so a clinician should review the health history first.

Q: Is pressure ulcer treatment covered by insurance?

A: Our services are covered by most major health insurance companies, but coverage varies by plan. Please check with your insurer and contact our team to confirm.

Q: Can treatment be given at home?

A: Yes. Mel Health Tech offers mobile home services as well as clinic appointments. Contact us to ask about availability in your area.

Conclusion

Pressure ulcers are easier to prevent than to treat, but when they do develop, early action matters. Effective pressure ulcer treatment starts with relieving pressure, then adds careful wound care, good nutrition, and regular monitoring. For wounds that are slow to respond, low frequency ultrasound therapy can be one part of a complete plan guided by a qualified healthcare professional.
