At a Glance: Healing a bedsore comes down to a few core steps that work together: take the pressure off the area, keep the wound clean and properly dressed, remove any dead tissue, support the body with good nutrition, and watch closely for signs of infection. For caregivers looking after a family member with limited mobility, consistent daily care and the right support surface give a wound its best chance to close.
A pressure sore, also called a bed sore, pressure ulcer, or pressure injury, is damage to the skin and the underlying tissue beneath it caused by sustained pressure. For caregivers supporting a family member with a disability or a mobility-limiting medical condition, knowing how to heal a bedsore and when to call in a healthcare provider is part of daily care.
Start by Relieving the Pressure
A bedsore cannot heal while the same pressure that caused it keeps cutting off the blood supply. Relieving that pressure is the first and most important step, and every other treatment depends on it.
For a patient with limited mobility, this means both hands-on care and the right surface underneath them:
- Frequent Repositioning: Turn and reposition the patient on a schedule, often every two hours in bed, to move pressure off the affected area and change contact points.
- Pressure-Relieving Devices: A pressure-redistributing mattress or cushion spreads body weight so no single point carries too much load. A standard mattress cannot provide this.
- Keep Pressure Off the Wound Directly: Position the patient so their body weight does not rest on the sore itself while it heals.
For a person who cannot reposition on their own, a therapeutic support surface carries much of this load between repositioning. The right surface works together with regular repositioning to relieve pressure, rather than relying on either one alone. Taking continuous pressure off the wound restores blood flow to the area, which allows new tissue to grow.
Keep the Wound Clean and Dressed
Once pressure is relieved, the wound needs to be cleaned and kept in an appropriately moist environment to heal. A wound that is too dry or too wet heals slowly.
- Clean Gently: The affected area is cleaned as directed by the care team, usually with saline rather than harsh antiseptics that can damage fragile skin and new tissue.
- Use the Right Dressing: Dressings hold in the right amount of moisture, protect the wound, and manage drainage. The type depends on the wound’s depth and how much fluid it produces.
- Protect the Surrounding Skin: Keeping the skin around the wound clean and dry helps prevent the sore from spreading.
A healthcare provider or wound care nurse can match the dressing to the wound and show a caregiver how to change it correctly.
Remove Dead Tissue
Healthy tissue cannot grow over dead tissue. When a wound contains necrotic tissue or slough, it often needs to be removed through a process called debridement before it can heal.
Debridement is done by a healthcare professional and takes several forms, from special dressings that break down dead tissue over time to surgical removal for deeper wounds. Removing necrotic tissue is a step for the care team, not something a caregiver should attempt at home.
Support Healing With Proper Nutrition
The body rebuilds tissue using the nutrients it takes in, so proper nutrition has a direct effect on how fast a wound heals. A patient who is undernourished has less protective tissue and heals slowly.
- Protein supports the growth of new tissue and is one of the most important nutrients for wound healing.
- Vitamins and minerals, including vitamin C and zinc, help the body repair the skin.
- Hydration keeps the skin and tissue healthy and supports circulation.
A balanced diet and enough fluids give the healing process what it needs. A healthcare provider may recommend supplements for a patient whose intake is low.
Watch for Signs of Infection
An open wound can become infected, and infection stalls healing and can become dangerous. Caregivers should check the wound daily and know the bedsore symptoms that signal a problem.
Signs of infection include:
- Increasing redness, warmth, or swelling around the wound
- Pus or fluid with a foul odor
- Increased pain at the affected area
- Fever or a general feeling of illness
If any of these appear, contact a healthcare provider promptly. In severe cases, an infected bedsore can lead to a deep tissue injury, a bone infection, or a blood infection, all of which need immediate medical treatment.
What Can Slow the Healing Process
Even with proper care, some risk factors make a bedsore harder to heal. Knowing them helps a caregiver understand why a wound may be slow to close.
- Limited Mobility: A patient who cannot move stays under continuous pressure, the single greatest obstacle to healing.
- Poor Circulation: Health conditions such as diabetes reduce blood flow, which slows the delivery of oxygen and nutrients to the wound.
- Moisture: Skin that stays damp from incontinence or sweat breaks down more easily.
- Age and Fragile Skin: Thin, fragile skin is more vulnerable to pressure and tears.
Patients with several of these factors are at higher risk of developing chronic wounds and pressure wounds that resist healing, which makes consistent care and pressure relief even more important.
When to Call a Healthcare Provider
Some bedsores can be managed at home with guidance, but others need extensive professional treatment. Contact a health care provider if the wound is deep, shows exposed tissue, is not improving after consistent care, or shows any signs of infection. Painful wounds, wounds that grow, and wounds that reach muscle or bone all call for immediate medical attention. A care team can assess the wound, adjust the treatment plan, and confirm that the patient has the right equipment at home.
The Right Support Surface Makes a Difference
Every step of healing a bedsore depends on keeping pressure off the wound, and that is difficult to do by hand alone for a patient with limited mobility. This is where the support surfaces become part of the treatment plan.
The right surface is also one of the strongest preventive measures against new wounds forming while an existing one heals. There are several types of pressure-relieving devices available, and matching the surface to the severity of the wound matters. A patient with a deeper or slow-healing wound often needs more support than a standard mattress or overlay can provide.
Support Bedsore Healing at Home with Ethos
Healing a bedsore requires a consistent plan: relieve the pressure, keep the wound clean and dressed, remove dead tissue, support the body with proper nutrition, and watch for signs of infection. For a patient who cannot move on their own, the surface underneath them does much of the work of protecting the wound between repositioning.
Ethos Therapy Solutions works with patients, families, and care teams to support wound healing at home. The air fluidized therapy beds, immersion beds, and mattress overlays and replacements available through Ethos are built to relieve pressure and protect skin for patients with limited mobility and advanced wounds. To find the right surface for a patient’s needs, contact the Ethos team.
