If you or a loved one have a severe, non-healing wound, a doctor might recommend a Wound Vac (also known as Negative Pressure Wound Therapy or NPWT). But how does a wound vac actually work, and why can it sometimes be painful?

In this video, hosts Kim Cantwell-Opazo and Dr. Michael Devine break down everything you need to know about negative pressure wound therapy with guest surgeons Dr. Brett Freedman and Dr. Michael Schuler from Clear Choice Therapeutics.

You'll learn how traditional wound vacs use black foam under suction, why high suction pressure can sometimes push down on the wound and reduce blood flow (the "Perfusion Paradox"), and how new clear, polymer-based dressings like PREVENT™ are changing wound care to make healing faster, cleaner, and much less painful!

💡 What You'll Learn:

What is a Wound Vac? How suction helps pull fluid away and close deep wounds.
The Blood Flow Danger: How high suction with traditional black foam can act like a tourniquet and cut off blood circulation to fragile tissue.
Pain & Odor Concerns: Why traditional foam causes pain during dressing changes (tissue growing into foam) and how new clear dressings prevent it.
Advancements in Healing: How lower suction and clear materials help doctors see the wound without taking the bandage off.
