Why most pressure injuries stall — and what wound care nurses actually use when they do.
The nurse comes on Tuesdays. She unpacks her bag onto a clean towel, washes her hands, and talks to the patient the whole time she works — not over her. She cleans the wound, places a small dressing on it, covers it, and writes a note for the chart. By Wednesday morning, the wound usually looks calmer than it did the day before. Then the door closes, and the other six days of the week begin.
Those six days belong to the family. In homes all over the country, they belong to adult sons and daughters — many in their forties, fifties, and sixties — who never trained for any of this and are doing it anyway: changing dressings at a parent's bedside, keeping notes on a phone, trying to reproduce on Thursday what a professional did on Tuesday.
It is one of the most common situations in home wound care, and one of the least talked about. A parent has a pressure injury — a bedsore, in the older language — that has stopped making progress. The visiting nurse brings supplies that seem to make a difference. And between visits, the family cannot find those supplies at any store in town.
This article is about why that gap exists — and what is actually inside the nurse's bag.
Why pressure injuries stall
Clinicians describe wound closure as a sequence of overlapping phases: the body controls bleeding, mounts an inflammatory response to clear away damaged tissue, rebuilds new tissue, and finally remodels it. Clinical guidelines from wound-care professional societies — including the Wound, Ostomy and Continence Nurses Society (WOCN) and the Association for the Advancement of Wound Care (AAWC) — describe pressure injury care in exactly these terms: not one problem, but several overlapping ones that have to be managed at the same time.
A wound that has stopped changing week over week is often called a stalled wound. In many stalled wounds, the process appears to be stuck in that early inflammatory phase — the wound environment keeps breaking material down faster than the body can build tissue up, and visible progress flattens out.
Three things tend to matter at once. Moisture balance: a wound bed that is too dry or too wet each creates its own problems, which is why clinicians pay so much attention to which dressing goes on and how often it is changed. Pressure off-loading: a pressure injury forms because of sustained pressure over bone; if that pressure continues, the conditions that created the wound are still present. The wound environment itself: what actually sits against the wound bed between changes.
This is why "just keep a bandage on it" is often not enough. A drugstore bandage covers a wound. It does little to address any of the reasons the wound stalled in the first place.
What the nurse's bag has that the drugstore doesn't
In wound clinics and skilled nursing facilities, one category of dressing shows up again and again on stalled wounds: the collagen matrix dressing.
A collagen dressing is simpler than it sounds. It is a sterile matrix of Type I collagen — the same structural protein that makes up much of the skin's own scaffolding — placed directly on the wound bed and held in place by a secondary dressing over the top. It is designed to provide a protein matrix at the wound surface, while the secondary dressing manages moisture and protects the site between changes.
Wound-care clinicians commonly reach for this category when a wound has plateaued. It is a professional product with decades of use in clinical settings — and it is almost never on a retail shelf.
If you've watched the nurse unwrap a small white square and wondered what it was — this is usually it.
Why families can't just buy it
Collagen dressings live inside the medical supply chain. They are sold through distributor accounts to clinics, facilities, and home-health agencies. In practice, many suppliers ask for a prescription or a provider account before they will ship, and the nurse's agency orders through channels a household simply doesn't have.
None of this is a conspiracy. It is a supply chain built for institutions and never rebuilt for households. But the result is familiar to families managing a pressure injury at home: the one day a week with the nurse is supplied by a professional catalog, and the six days in between are supplied by whatever the drugstore carries.
That is the gap Ovena Health was built to close. Ovena — founded by David Chahine, MD — makes FDA 510(k)-cleared collagen matrix dressings available directly to families, without a distributor account. And rather than shipping a lone box of dressings, Ovena packages them the way a nurse actually works: five sealed collagen dressings, sterile saline wound wash for cleansing, nitrile gloves for clean changes, and medical tape to secure it all — together in one kit.
What families can do this week
Whatever supplies are in the cabinet, four habits make the six days between visits calmer and more useful to the care team.
- Ask the nurse what dressing she's using. Write down the exact product name and category, and ask how she would like changes handled between visits.
- Photograph and log each dressing change. A dated photo log shows the care team week-over-week change that memory alone can't.
- Keep pressure off the site, per the care plan. Repositioning schedules and support surfaces are part of the treatment — not extras.
- Stock matched supplies so changes never have to wait. A skipped or improvised dressing change is one of the most common gaps in home care.
When to call the clinician
Some changes should not wait for the next scheduled visit. Call the care team promptly for any of the following:
- Spreading redness around the wound
- New warmth at or around the site
- A new or worsening odor
- Fever or chills
- A sudden increase in pain
When in doubt, call. No dressing replaces clinical judgment.
The six days between visits don't have to be guesswork.

Common questions
Is this medical advice?
No. This is educational content from a company that makes wound-care products. Decisions about dressings, wound care, and pressure injuries should always be made with the treating care team — the visiting nurse, wound clinic, or physician who knows the wound.
Is Ovena's collagen the same category the clinic uses?
Yes. Ovena's collagen dressings are FDA 510(k)-cleared collagen matrix dressings — the same product category used in wound clinics and skilled nursing facilities.
What if the wound is already being managed by a clinic?
Even better. Bring the kit to the next visit and ask the clinician whether it fits the current care plan — matched supplies only help when they match the plan, too.
