Wound Care Essentials

A patient-friendly primer on how wounds heal, why some get stuck, and what the care team is watching for at every visit. The through-line: acute wounds close on their own, chronic wounds need the underlying cause fixed.

The healing map

Skin has three layers — the outer layer protects, the middle layer rebuilds, and the deep layer cushions muscle and bone. The deeper a wound goes, the more support it needs. Healing then moves through four overlapping phases:

1. Hemostasis — bleeding stops within minutes.
2. Inflammation — the body cleans the area over a few days.
3. Proliferation — new tissue fills the gap over weeks.
4. Remodelling — the skin slowly regains strength over months.

What clinicians check with TIME

At each visit, nurses run a simple checklist to read the wound bed consistently:

• Tissue — is it healthy or needs debridement?
• Infection — signs of bacterial burden?
• Moisture — balanced, not too wet or dry?
• Edges — advancing or stalled?

Pairing a measured photo with these notes makes progress visible even when day-to-day change feels slow. Tools like AI-powered wound imaging and a healing dashboard help the team trend the same details over time.

Red flags to call the clinic

Spotting infection early matters. Warning signs include increasing pain, spreading redness, warmth and swelling, pus, or a bad smell. Fever or feeling generally unwell is an urgent reason to seek help right away.

What stalls a diabetic foot ulcer — and every chronic wound

Poor blood flow, infection, high blood sugar, weak nutrition, ongoing pressure, and smoking are the most common culprits. Good care comes down to four principles working together: treat the root cause, prepare the wound bed, keep it moist with the right dressing, and reassess regularly.
