Wound Vac / NPWT Therapy at Home — St. Louis

A nurse practitioner places, manages, and monitors your wound vac in your home or facility — no outpatient clinic visits, no transportation burden. Medicare-covered when eligible.

NP-Led Bedside Setup Dressing Changes at Home Medicare NPWT Covered* 24–48 Hour Response
Overview

Negative Pressure Wound Therapy, Delivered at the Bedside

Negative pressure wound therapy (NPWT) — commonly called a “wound vac” — is one of the most effective interventions for complex, slow-healing wounds. A sealed foam or gauze dressing is connected to a small pump that applies controlled sub-atmospheric pressure. The therapy actively removes exudate, reduces edema, approximates wound edges, and stimulates the formation of healthy granulation tissue.

Traditionally, NPWT has meant weekly outpatient clinic visits for dressing changes. Gateway Wound Care eliminates those trips. Our nurse practitioners set up the device, perform dressing changes, troubleshoot leaks and alarms, manage pain, monitor for infection, and coordinate with the DME supplier — all in the patient’s home, assisted living facility, or skilled nursing community.

We provide NPWT in coordination with our dedicated wound vac service line, serving patients across Chesterfield, Creve Coeur, Kirkwood, and the entire Gateway service area.

Indications

When Is a Wound Vac Appropriate?

NPWT is a powerful therapy, but it is not the right choice for every wound. Our nurse practitioners evaluate each patient against established clinical criteria and Medicare coverage requirements before recommending vac therapy.

NPWT is contraindicated in untreated osteomyelitis, malignancy in the wound, exposed blood vessels or organs, necrotic tissue with eschar, and certain fistulas. Our NPs rule out contraindications at the first visit.

How It Works

The Gateway Home NPWT Workflow

1

Evaluation & Coverage

An NP assesses the wound, confirms NPWT is clinically appropriate, and documents the Medicare LCD-required criteria. Our care coordinator verifies benefits and submits orders to the DME provider.

2

At-Home Setup

Once the pump is delivered, we place the first foam or gauze dressing, apply the drape, set the pressure (typically -125 mmHg), confirm a good seal, and educate patient and caregivers on alarms, drainage canister changes, and activity.

3

Scheduled Dressing Changes

Every 48–72 hours a Gateway NP returns to change the dressing, measure the wound, document photos and progress, troubleshoot leaks, and transition to standard dressings when the vac is no longer needed.

What to Expect

Day-to-Day with NPWT at Home

🔌

Portable, Quiet Devices

Modern NPWT pumps are small and battery-powered — typical device weight is 2–3 pounds and can be worn over the shoulder. Most patients can bathe, sleep, and perform daily activities with minimal disruption.

📞

Between-Visit Support

If an alarm sounds or the dressing leaks between scheduled visits, patients and caregivers call Gateway directly. We troubleshoot by phone and, when needed, dispatch an NP for an unscheduled visit.

🩹

Coordinated with Other Care

Gateway’s NPs perform debridement, graft aftercare, and other wound services alongside NPWT — one unified care team, one clinical record.

📊

Progress Documentation

Every visit is photographed and measured. Reports go to the referring physician so primary care, surgery, or podiatry always know how the wound is progressing.

For DME providers & home-health agencies: Gateway partners with KCI (3M), Cardinal Health, and other leading NPWT device lines. We accept wound vac referrals from agencies that need an NP to own the clinical management. Fax clinical summary to (314) 689-1318.

Common Questions

Frequently Asked Questions — Wound Vac / NPWT

Negative pressure wound therapy — often called a wound vac — applies controlled sub-atmospheric pressure to a sealed wound through specialized foam or gauze dressing. The system removes exudate, reduces edema, increases local blood flow, draws wound edges together, and promotes granulation tissue formation. NPWT is evidence-based for qualifying diabetic foot ulcers, pressure injuries, post-surgical wounds, and traumatic wounds. Gateway initiates and manages NPWT in St. Louis homes — no travel to a clinic required.
A wound vac sits on a small, portable pump connected by tubing to a foam dressing sealed over the wound with an adhesive drape. The pump creates continuous or intermittent negative pressure (typically 75–125 mmHg) that pulls fluid and infectious material into a collection canister. The pressure also mechanically stresses the wound bed at the cellular level, stimulating new tissue growth. Dressings are typically changed 2–3 times per week. Gateway NPs manage this at the bedside throughout Greater St. Louis.
NPWT duration is individualized. Most patients use a wound vac for 2–8 weeks — long enough to fill the wound with healthy granulation tissue. Some deep or complex wounds need longer courses. Medicare caps coverage at a maximum therapy duration (typically 4 months), after which continued use requires documented medical necessity. The goal is not to keep the pump on indefinitely; it's to transition to standard dressings once the wound has filled in adequately.
Yes, when coverage criteria are met. Medicare Part B covers NPWT for qualifying wounds (Stage 3–4 pressure injuries, neuropathic ulcers, venous insufficiency ulcers, chronic post-surgical wounds, flaps or grafts, traumatic wounds) after documentation of failed conventional therapy and with appropriate physician orders. The pump, canisters, and dressings are covered. Gateway handles the benefit verification, prior authorization paperwork, and DME coordination for St. Louis patients before starting therapy.
Yes — modern wound vac systems are designed specifically for outpatient and home use. The portable pump weighs 2–4 pounds, fits in a carrying case or on a belt, and runs on rechargeable battery for several hours between charges. You can sleep, bathe (with the proper cover), and in most cases walk or travel short distances. Gateway trains patients and caregivers on every aspect of at-home operation during the initial St. Louis visit, and we're reachable by phone when questions come up.
Most patients report mild pulling or suction sensation rather than pain during therapy. Dressing changes — when the foam is removed from the wound bed — can be uncomfortable; Gateway uses techniques such as soaking the foam with saline before removal, adjusting pressure settings, and timing dressings around prescribed pain medication to minimize discomfort. Persistent or worsening pain during active therapy is not normal and should be reported right away — it can indicate infection, wound edge trauma, or system malfunction.
Standard wound vac dressing changes occur 2–3 times per week (typically Monday/Wednesday/Friday). Some deep or infected wounds require more frequent changes in the first week. Each change is performed sterilely and includes wound measurement, photo documentation, cleaning, foam cutting and placement, and system priming. Gateway schedules these visits at consistent times to keep your St. Louis home routine predictable.
Medicare-approved indications include Stage 3 and Stage 4 pressure injuries, neuropathic (diabetic) ulcers, venous insufficiency ulcers, chronic ulcers present for at least 30 days that have failed conservative therapy, dehisced surgical wounds, traumatic wounds, and wounds over flaps or grafts. The wound must have adequate perfusion, no untreated osteomyelitis, no exposed vital structures without protective interface, and no active malignancy in the wound bed. Gateway evaluates candidacy at the first St. Louis assessment visit.
Some patients can shower with the vac disconnected for up to 2 hours per day (the system tolerates brief disconnection). The foam dressing itself usually must stay dry and sealed. Sponge baths and showering with a waterproof cover over the dressing are more common options. Never submerge the dressing in a bathtub. Gateway will give you specific showering instructions based on your device model, wound location, and care plan during your first St. Louis visit.
Traditional dressings are passive — they absorb drainage and maintain a moist wound environment. NPWT is active — it removes drainage continuously, reduces edema, and mechanically stimulates tissue growth. For qualifying wounds, NPWT typically produces faster granulation, shorter healing times, and fewer dressing changes per week. For superficial or low-drainage wounds, traditional dressings work well and are less expensive. Gateway selects the right therapy for each wound — NPWT is a tool, not a default.
