Negative Pressure Wound Therapy, often called NPWT, wound VAC therapy, or vacuum-assisted closure, is an advanced wound care option that uses controlled suction through a specialized dressing system.
When clinically appropriate, negative pressure wound therapy may be considered for certain wounds with drainage, depth, delayed healing, surgical complications, pressure injury concerns, or other factors that require careful wound management.
Advanced Wound Care of Arizona provides mobile wound care for patients who need skilled wound evaluation, treatment support, and care coordination without the difficulty of traveling to a wound care center.

If you or a loved one has a diabetic ulcer, pressure sore, surgical wound, venous or arterial ulcer, extremity wound, or non-healing wound, contact our team to discuss whether mobile wound care may be appropriate.
Negative Pressure Wound Therapy is a wound care treatment that uses controlled suction to help manage a wound environment.
A specialized dressing is placed over the wound and sealed with a clear adhesive cover. Tubing connects the dressing to a therapy unit or pump, which applies negative pressure. The system may help remove wound fluid, manage drainage, and support the wound environment when clinically appropriate.
Patients and caregivers may hear this treatment called:
The names can be confusing, but the general idea is the same: a sealed dressing system uses controlled suction as part of a wound care plan.
Negative pressure wound therapy is not used for every wound. It is one possible tool within a broader plan that may also need to address infection risk, circulation, pressure, swelling, tissue condition, drainage, mobility, nutrition, and coordination with the patient’s care team.
A chronic, complex, or delayed-healing wound usually has a reason it is not improving.
A surgical wound may be affected by drainage, infection risk, wound separation, or tension on the incision. A pressure sore may be affected by ongoing pressure, shear, friction, moisture, or limited mobility. A diabetic ulcer may be affected by neuropathy, pressure, blood sugar, infection risk, or circulation problems. A venous or arterial ulcer may be affected by swelling, vein disease, poor blood flow, or pressure.
Negative pressure wound therapy may help manage the wound environment when appropriate, but it does not replace the need to address those underlying issues.
A complete wound care plan may include:
The goal is not simply to place a device. The goal is to choose the right care steps for the wound and the patient.
Patients and caregivers often wonder when a wound may need more than basic dressing changes.
This quick guide can help:
This table is only a general guide. A qualified wound care provider should evaluate the wound and the patient’s overall condition before treatment decisions are made.
If a wound is rapidly worsening, has spreading redness, fever, severe pain, heavy drainage, black tissue, exposed bone or tendon, uncontrolled bleeding, a cold or discolored foot, or the patient appears very ill, seek urgent medical attention.
Negative pressure wound therapy usually involves a sealed dressing system.
A wound care clinician may place a specialized dressing material into or over the wound, cover it with a clear adhesive drape, and connect tubing to a therapy unit. The system applies controlled suction to the wound area.
Depending on the wound and the device, NPWT may help:

Depending on the wound and the device, NPWT may help:
Negative pressure wound therapy depends on a proper seal.
If the dressing seal is loose, leaking, wrinkled, wet, or disrupted, the device may not work as intended. The patient or caregiver may hear an alarm, notice drainage problems, or see that the dressing is not staying in place.
A good seal can be harder to maintain when the wound is near:
This is one reason NPWT requires careful monitoring and follow-up.
Patients and caregivers should not try to rebuild, pack, tighten, or change a negative pressure wound therapy dressing unless they have been trained and instructed to do so.
Not every wound needs negative pressure wound therapy. Some wounds may be better managed with other forms of care. Others may need urgent medical attention, infection treatment, vascular evaluation, pressure relief, surgical follow-up, or another type of support.
NPWT may not be appropriate depending on:
The wound care clinician determines whether negative pressure wound therapy may be appropriate based on the wound and the patient’s overall situation.
Patients and caregivers should not assume that any advanced treatment is automatically right for every wound.
Negative pressure wound therapy may be considered for different wound types when clinically appropriate.
Some surgical wounds need additional support when healing is delayed, drainage continues, infection is a concern, or the incision has opened.
NPWT may be considered for certain post-surgical wounds when the wound type, drainage, tissue condition, and overall care plan support its use.
Pressure sores may be affected by ongoing pressure, shear, friction, moisture, skin fragility, limited mobility, and nutrition concerns.
Negative pressure wound therapy may be considered for some pressure sores when the wound depth, drainage, pressure control, patient health, and overall care plan support its use.
Venous and arterial ulcers are often related to circulation problems, swelling, vein disease, reduced blood flow, or pressure.
Negative pressure wound therapy may be considered for some ulcers, but circulation and swelling concerns still need careful evaluation. NPWT does not replace the need to address compression safety, vascular concerns, pressure, or other medical factors.
Venous and arterial ulcers are often related to circulation problems, swelling, vein disease, reduced blood flow, or pressure.
UltraMIST may be considered as part of a wound care plan, but circulation concerns still need careful evaluation. A treatment device does not replace the need to address swelling, compression safety, vascular concerns, or other medical factors.
A non-healing wound may stay open, drain, reopen, or fail to improve because several barriers are happening at the same time.
NPWT may be considered when the wound care team believes controlled suction and drainage management may support the wound environment as part of a broader care plan.
Wounds on the hands, arms, legs, feet, heels, toes, elbows, knees, hips, or other extremities may be affected by movement, pressure, footwear, braces, mobility devices, fragile skin, diabetes, or circulation problems.
Negative pressure wound therapy may be considered for some extremity wounds when clinically appropriate.
Negative pressure wound therapy is usually considered only after the wound has been evaluated carefully.
A wound may need attention first if there is:
If the wound environment is not appropriate, NPWT may not be the right next step.
This is why wound evaluation, measurements, debridement when appropriate, infection monitoring, pressure relief, and care coordination matter.
Many patients with chronic or complex wounds have difficulty traveling to repeated appointments. Some are homebound. Some have limited mobility, diabetes, pressure sores, circulation problems, surgical wounds, or wounds that require ongoing monitoring.
Advanced Wound Care of Arizona brings wound care services to patients when mobile care is appropriate.
When clinically appropriate, negative pressure wound therapy may be used or coordinated as part of a mobile wound care plan.
This can be helpful for:
Our goal is to make appropriate wound care more accessible while helping patients and care partners understand the wound, the care plan, and the next step.
The first step is understanding the wound and the patient’s overall care situation.
During a mobile wound care visit, the wound care clinician may evaluate the wound, review wound history, document wound characteristics, discuss current concerns, and help determine what type of care may be appropriate.
A visit may include:
Every wound is different. The care plan depends on the wound type, location, depth, drainage, skin condition, infection risk, circulation, pressure, mobility, pain level, and the patient’s overall health
When negative pressure wound therapy is appropriate, the wound care team may place or coordinate a specialized dressing system.
The details of care may depend on:
The dressing may need to stay sealed and connected to the therapy unit as directed. Dressing changes are done according to the care plan and the device or clinical protocol.
Patients and caregivers should follow instructions closely and should not turn off the device, disconnect tubing, remove foam or dressing material, or try to repair the dressing unless they have been told exactly what to do.
Negative pressure wound therapy may involve alarms or device alerts. These can happen for reasons such as a leak in the seal, a full canister, tubing problems, low battery, blockage, or a device issue.
Patients and caregivers should know:
Patients and caregivers should not ignore device alarms or leaks.
If the device stops working, the dressing seal is lost, bleeding occurs, the wound becomes more painful, or the patient develops fever or other urgent symptoms, contact the care team promptly or seek urgent medical attention depending on the situation.
Advanced wound care should be guided by wound progress, not guesswork.
The wound care team may track:
Some wounds may need photos or documentation when appropriate and permitted by the care setting. The purpose is to compare changes over time and help determine whether the care plan should continue, change, or involve additional providers.
Patients and caregivers should report changes promptly, especially if the wound becomes more painful, drains more, develops odor, becomes red or swollen, opens deeper, bleeds unexpectedly, or begins to look darker or dead-looking.
Negative pressure wound therapy may sound like the most important part of the treatment plan, but the basics still matter.
A wound may not improve if the main barrier to healing is still present.
For example:
NPWT may support the wound environment when appropriate, but it does not replace careful wound evaluation, pressure relief, infection monitoring, dressing selection, circulation assessment, or coordination with the patient’s care team.
Negative pressure wound therapy may be used along with other wound care options when clinically appropriate.
A care plan may include:
The right combination depends on the wound and the patient.
Negative pressure wound therapy should only be used when a trained healthcare professional determines that it is appropriate.
Patients and caregivers should tell the wound care team about:
This information helps the care team determine whether NPWT is appropriate and whether additional coordination is needed.
If symptoms are urgent or severe, the patient should seek immediate medical attention.
Wound care does not end when the visit ends. What happens between visits matters.
Patients and caregivers may receive guidance about:
Patients and caregivers should follow the care instructions provided by the wound care team and the patient’s other healthcare providers.
Do not turn off the device, remove dressing material, pull out foam, change device settings, apply home remedies, soak the wound, remove tissue, pull off scabs, massage red areas, tighten wraps, change footwear, or modify braces without clinical guidance.
Patients and caregivers can often help by watching the wound, dressing, device, and nearby skin closely.
Helpful steps may include:
If NPWT is already being used, ask the wound care team who to contact for wound concerns, device alarms, supply concerns, dressing issues, or urgent symptoms.
Negative pressure wound therapy often involves more than one provider, caregiver, or support partner.
Advanced Wound Care of Arizona may coordinate with:
Clear communication helps everyone understand the wound care plan, dressing changes, device concerns, follow-up needs, and warning signs that should not be ignored.

Negative pressure wound therapy is an advanced wound care option that uses controlled suction through a sealed dressing system. It may help manage drainage and support the wound environment when clinically appropriate.
NPWT stands for Negative Pressure Wound Therapy.
Many patients and caregivers use the term wound VAC therapy to describe negative pressure wound therapy. The general idea is a sealed dressing system connected to a therapy unit that applies controlled suction.
Negative pressure wound therapy may be considered for certain surgical wounds, pressure sores, diabetic ulcers, venous or arterial ulcers, extremity wounds, and non-healing wounds when clinically appropriate.
No. Negative pressure wound therapy is not used for every wound. The decision depends on the wound type, tissue condition, drainage level, infection risk, circulation, bleeding risk, patient health, and the overall care plan.
Mobile wound care may be appropriate for some patients. Advanced Wound Care of Arizona provides wound evaluation, treatment support, and care coordination in homes, assisted living settings, residential care environments, and other appropriate care locations within our active service area.
Advanced Wound Care of Arizona currently serves Coconino County, Maricopa County, Mohave County, and Yavapai County.
No. NPWT does not remove the need for wound monitoring or dressing management. The dressing must be changed according to the care plan, and the wound still needs follow-up evaluation.
Follow the instructions provided by the care team or device supplier. If the alarm does not resolve, the dressing seal is lost, drainage changes suddenly, bleeding occurs, the patient has increased pain, or urgent symptoms develop, contact the appropriate care team or seek urgent medical attention depending on the situation.
Wound progress may be tracked through measurements, drainage changes, tissue appearance, pain level, odor, surrounding skin condition, and whether the wound is getting smaller, larger, or staying the same.
NPWT is not appropriate for every patient. The care team should review the wound, medical history, bleeding risk, circulation status, infection risk, exposed structures, patient safety, and other factors before determining whether treatment is appropriate.
A wound may need urgent medical attention if it rapidly worsens, has spreading redness, increasing swelling, a foul odor, fever, severe pain, heavy drainage, black tissue, exposed bone or tendon, uncontrolled bleeding, a cold or discolored foot, or other concerning symptoms. If symptoms are urgent or severe, seek immediate medical care.
Yes. Family members and caregivers often contact Advanced Wound Care of Arizona on behalf of a parent, spouse, or loved one.
