How To Prevent Bed Sores At Home
Pressure sores — also called bedsores or pressure injuries — are one of the most serious and preventable complications facing patients who spend extended time in bed or in a wheelchair. They develop when sustained pressure cuts off blood flow to the skin, causing tissue to break down. Left untreated, they can progress from a mild redness to a deep, life-threatening wound within days.
The good news: with the right knowledge, routine, and equipment, the vast majority of pressure sores are entirely preventable. This guide gives you everything you need to protect your loved one at home.
⚠️ Who Is Most at Risk?
Understanding Vulnerability
Immobile Patients
Stroke, spinal cord injury, ALS, advanced dementia — anyone unable to shift their own weight
Elderly Individuals
Aging skin is thinner, less elastic, and has reduced blood flow — making it far more susceptible to breakdown
Incontinence
Prolonged moisture from urine or stool rapidly softens and weakens skin, dramatically increasing injury risk
Poor Nutrition
Protein and vitamin deficiencies impair skin integrity and slow wound healing — malnutrition is a major risk multiplier
Post-Surgical Patients
Extended bed rest after hip, knee, or spinal surgery creates sustained pressure on bony prominences
Diabetes & Vascular Disease
Reduced circulation and nerve sensitivity mean injuries develop faster and are harder to detect early
📍 The Most Vulnerable Body Sites
Where Sores Develop First
Pressure sores form where bone is close to the skin surface and sustained weight compresses the tissue. The most common sites depend on the patient's primary position:
🛏️ When lying in bed:
- Sacrum & coccyx (tailbone) — most common
- Heels & ankles
- Shoulder blades
- Back of the head
- Hips (greater trochanter)
🪑 When seated in a wheelchair:
- Ischial tuberosities (sitting bones)
- Coccyx & sacrum
- Back of knees
- Shoulder blades
🏆 The 5 Pillars of Bed Sore Prevention
Your Complete Prevention Framework
🔁 Pillar 1 — Regular Repositioning
Repositioning is the single most effective intervention for preventing pressure sores. The goal is to relieve pressure on vulnerable areas before tissue damage begins.
- ⏰ Every 2 hours for bed-bound patients — use a repositioning schedule and log
- ⏰ Every 15–30 minutes for wheelchair users — weight shifts or tilt-in-space
- 📐 Use the 30-degree lateral tilt position (not full side-lying) to avoid hip pressure
- 📌 Place a pillow between the knees when side-lying to prevent ankle and knee contact
- 📌 Keep the head of bed below 30° when possible to reduce shear forces on the sacrum
🛡️ Pillar 2 — Skin Inspection & Care
Daily skin inspection is non-negotiable. Catching early signs — redness, warmth, or firmness — allows intervention before a wound develops.
✅ Daily Skin Routine
- Inspect all bony prominences daily
- Cleanse skin gently with pH-balanced soap
- Apply moisture barrier cream to at-risk areas
- Pat dry — never rub
- Check for redness that does not blanch
❌ What to Avoid
- Massaging reddened areas (increases damage)
- Hot water or harsh soaps
- Dragging the patient across sheets (shear)
- Leaving wet or soiled linens in contact with skin
- Tight clothing or wrinkled bedding
🛏️ Pillar 3 — The Right Support Surface
A standard mattress is not designed for patients at pressure injury risk. Therapeutic support surfaces redistribute pressure, manage moisture, and reduce shear — the three primary mechanical causes of skin breakdown.
🥑 Pillar 4 — Nutrition & Hydration
Skin integrity is built from the inside out. Patients at risk of pressure sores require targeted nutritional support to maintain tissue resilience and support healing if a wound does develop.
Protein
1.2–1.5g per kg body weight daily. Essential for tissue repair and immune function.
Hydration
Dehydrated skin loses elasticity and breaks down faster. Aim for 6–8 glasses of water daily.
Vitamins C & Zinc
Both are critical for collagen synthesis and wound healing. Deficiency significantly slows recovery.
🪑 Pillar 5 — Wheelchair & Seating Cushions
For patients who spend time in a wheelchair or recliner, the seating surface is just as important as the mattress. A standard foam seat cushion provides minimal pressure relief. Clinical-grade cushions use air, gel, or hybrid systems to redistribute pressure across the ischial tuberosities and coccyx.
ROHO® HYBRID ELITE® Cushion
The gold standard in air-cell seating. ROHO's interconnected air cells conform to the body's contours, eliminating peak pressure points at the sitting bones. Sensor-ready for pressure mapping.
View Product ›Titanium Gel/Foam Wheelchair Cushion
A hybrid gel-and-foam design that combines the pressure-absorbing properties of gel with the postural support of contoured foam. Ideal for patients who need both skin protection and positioning stability.

Early Detection Saves Lives
| Stage | Appearance | Action Required |
|---|---|---|
| Stage I | Non-blanchable redness on intact skin | Increase repositioning frequency; apply barrier cream; review support surface |
| Stage II | Partial thickness skin loss; shallow open wound or blister | Contact a wound care nurse; upgrade to therapeutic mattress; strict offloading |
| Stage III | Full thickness skin loss; subcutaneous tissue visible | Urgent medical attention; low air loss mattress; specialist wound care |
| Stage IV | Full thickness tissue loss; bone, tendon, or muscle exposed | Emergency medical care; hospitalisation may be required |
