Wound care at GRMC
GRMC’s wound care clinic offers a wide range of leading-edge therapies and treatments. These include:

  • Hyperbaric oxygen therapy
  • Compression therapy
  • Negative pressure wound therapy (wound VAC)
  • Offloading treatments, which keep pressure off wounds to promote healing
  • Specialized wound dressings
  • Skin substitutes, an alternative to skin grafts

Our wound care specialists will also work with you to determine why your wound may not be healing properly. For example, an ankle-brachial index test can identify problems with circulation, such as peripheral artery disease. Treating underlying conditions can help you heal—and help prevent non-healing wounds in the future.

At GRMC, our progressive approach means your care doesn’t end when you leave our clinic. In addition to follow-up care at our wound center, we can help connect you with other services as needed, including home health services, nutrition counseling, physical therapy and vascular specialists.

Hyperbaric oxygen therapy at GRMC
Breathing pure oxygen in a pressurized environment can increase the amount of oxygen in the blood. For about 10% of patients, hyperbaric oxygen therapy (HBOT), breathing pure oxygen in a pressurized environment, can help wounds heal faster and more effectively when used in combination with other treatments.

Some benefits of HBOT include:

  • Reduced swelling for crush injuries.
  • Increased circulation as your body forms new blood vessels.
  • Increased oxygen in your blood and tissues.

At GRMC, our two state-of-the-art hyperbaric chambers offer high-tech healing in a comfortable environment. And our highly trained and certified staff is there to make sure you have a safe and comfortable experience. Your wound treatment team will let you know what to expect during and after HBOT, so you can make the most of your treatment.

Most HBOT sessions last from 90 to 120 minutes. Our chambers are transparent, and you’ll have access to a television during your sessions—but many patients use the time to nap and relax.

You will likely feel some improvement after a few HBOT sessions. However, a normal course of treatment includes around 60 visits. .
