Hyperbaric Oxygen Therapy For Non-Healing Wounds

Non-Healing Wounds

Non-healing (or Chronic) wounds are certain wounds that fail to heal within a certain time period, typically 4 weeks or longer. Ulcers are the most common type of non-healing wound, but there are several types of wounds that have the potential to be non-healing depending on a number of factors. If left untreated, non-healing wounds can lead to infection and/or illnesses and in extreme cases the loss of limbs.

Examples of non-healing/
chronic wounds:

  • Diabetic Ulcers
  • Venous Ulcers
  • Arterial/Ischemic Ulcers
  • Pressure Wounds (Bedsores/Decubitus Ulcers)

Common Causes of Non-Healing Wounds

Non-healing wounds can occur because of many underlying reasons that are also affecting the body’s ability to heal the wound:

  • Poor Circulation

    Leads to improper deliveries of oxygen and essential nutrients to the wound site and removal of toxins and bacteria, which can hinder the body’s ability to heal wounds. Poor circulation can be caused by other conditions that affect proper blood flow (e.g., High blood pressure, diabetes).

  • Age

    As we get older, our skin becomes more fragile, and our bodies do not produce as many antibodies. This can lead to more frequent or stronger infections. We also become more susceptible to common conditions that lead to poor circulation like Diabetes and Heart disease

  • Trauma

    Repeated trauma to the wound (rubbing, bumping, added pressure) can affect the speed in which the wound heals.

  • Infection

    Infections (Fungal, Bacterial, Viral) around/in the wound site can delay the healing process. Infections that originated near bone have the potential to rise to the surface and form lesions.

  • Medication

    Certain medications, in particularly chemotherapy and radiation therapy drugs can increase the risk of infections and non-healing wounds

  • Diabetes

    Having steadily high blood glucose levels weakens the functionality of white blood cells, worsening the body’s ability to heal wounds or fight infections.

Non-Healing Wounds Symptoms

  • Dark outer skin around the wound site
  • Discharges of pus (green/yellow) or excessive fluid (clear)
  • Excessive bleeding
  • Redness
  • High levels of pain

Conventional Treatments


Removal of the dead tissue, application of new dressings with a medicated ointment or gel


Ointments can be described for Ulcers that aid in preventing further infection or tissue dying


How Hyperbaric Oxygen Therapy Can Help

HBOT increases the level of oxygen concentration in the blood, enhancing the blood supply to the affected areas allowing for the development of new tissue. HBOT also increases the production of white blood cells which can aid in killing bacteria and fighting infections at the wound site.
