1. Hyperoxygenation and Bubble Size Decrease

Mechanisms of Action

Hyperbaric Oxygen Therapy (HBOT) primarily works through two key mechanisms: hyperoxygenation and the reduction of bubble size. These mechanisms play a crucial role in enhancing tissue oxygenation and metabolic functions.


  • Enhanced Tissue Oxygenation: HBOT involves breathing pure oxygen in a pressurized chamber, which increases the amount of oxygen dissolved in the blood plasma. This elevated partial pressure of arterial oxygen significantly enhances tissue oxygenation.
  • Improved Metabolic Functions: With more oxygen available, cellular metabolism is optimized, supporting various biochemical processes essential for wound healing. Enhanced oxygen levels facilitate ATP production, collagen synthesis, and other critical metabolic functions.

Role of Boyle’s Law

Boyle’s law states that the volume of gas is inversely proportional to the pressure exerted on it. Under hyperbaric conditions:

  • Bubble Size Reduction: The increased pressure within the hyperbaric chamber reduces the size of gas bubbles in tissues. This is particularly important for managing decompression sickness and arterial gas embolism.
  • Prevention of Tissue Damage: Smaller bubbles reduce mechanical stress on tissues, preventing further damage during hyperbaric exposures.

Relevance to Wound Healing Processes

The mechanisms of hyperoxygenation and bubble size decrease are integral to promoting wound healing:

  • Angiogenesis: Elevated oxygen levels stimulate the formation of new blood vessels, ensuring an adequate supply of nutrients and oxygen to the wound site.
  • Fibroblast Proliferation: Enhanced tissue oxygenation promotes fibroblast activity, leading to increased synthesis of extracellular matrix components necessary for tissue regeneration.

By understanding these primary mechanisms, you can better appreciate how HBOT contributes to effective wound healing.

2. Vasoconstriction, Angiogenesis, and Fibroblast Proliferation

Vasoconstriction, angiogenesis, and fibroblast proliferation are secondary mechanisms of action for Hyperbaric Oxygen Therapy (HBOT). These processes play crucial roles in the wound healing cascade.


  • Vasoconstriction aids in reducing edema in the wound area.
  • This reduction in swelling is vital as it helps prevent further tissue damage.
  • By narrowing blood vessels, vasoconstriction also facilitates the formation of new blood vessels, a process essential for effective wound healing.


  • Angiogenesis ensures an adequate supply of nutrients and oxygen to the wound site.
  • The development of new blood vessels enhances the delivery of these critical elements, promoting faster and more efficient healing.
  • An increased oxygen gradient between the center and periphery of the wound creates a strong stimulus for angiogenesis.

Fibroblast Proliferation

  • Fibroblast proliferation is central to synthesizing extracellular matrix components necessary for tissue regeneration.
  • Fibroblasts contribute to collagen production, which forms the structural framework required for new tissue development.

These mechanisms collectively enhance the body’s ability to repair and regenerate damaged tissues.

HBOT has shown promising results not only in wound care but also in other areas such as sports injuries and diabetes-related neuropathy. For sports injuries, HBOT can stimulate the production of new blood vessels, improving blood flow and oxygen delivery to injured tissues.

3. Leukocyte Oxidative Killing and Modulation of Inflammatory Response

Leukocyte oxidative killing plays a critical role in the body’s defense against infections, especially in wounds that are slow to heal. Hyperbaric Oxygen Therapy (HBOT) improves this process by making leukocytes produce more reactive oxygen species (ROS). These extra ROS can effectively destroy harmful bacteria and other pathogens, helping to resolve long-lasting infections commonly found in non-healing wounds.

How HBOT Enhances Leukocyte Oxidative Killing

HBOT enhances leukocyte oxidative killing through two main mechanisms:

  • Increased ROS Production: By exposing the body to high levels of pure oxygen under pressure, HBOT stimulates leukocytes to produce more ROS. This “oxidative burst” strengthens their ability to kill bacteria and other microorganisms.
  • Improved Oxygen Delivery: HBOT also increases the amount of dissolved oxygen in the blood plasma, which can reach areas with poor blood circulation. This ensures that leukocytes have enough oxygen to carry out their antimicrobial functions effectively.

The Role of HBOT in Modulating Inflammation

In addition to boosting leukocyte activity, HBOT also helps regulate the body’s inflammatory response, which is crucial for wound healing. Here’s how it works:

  • Cytokine Regulation: HBOT influences the production and activity of various cytokines, which are small proteins involved in cell signaling. By modulating cytokine levels, HBOT can reduce excessive inflammation and promote a more balanced immune response.
  • Immune Cell Function: HBOT enhances the function of immune cells, such as macrophages and neutrophils, which play key roles in inflammation and tissue repair. This improved immune cell activity helps prevent chronic inflammation that could delay wound healing.

The Connection Between HBOT, Wound Healing, and Neurological Conditions

The mechanisms of leukocyte oxidative killing and inflammation modulation by HBOT have broader implications beyond wound healing. They also relate to neuroplasticity (the brain’s ability to reorganize itself) and recovery in neurological conditions like traumatic brain injury (TBI):

  • Reducing Swelling and Further Damage: The anti-inflammatory effects of HBOT may help reduce swelling and prevent additional harm to injured neural tissues in cases of TBI.
  • Promoting Neuroplasticity: By creating a favorable environment with less inflammation and improved oxygenation, HBOT could potentially support neuroplasticity processes and enhance functional recovery in individuals with neurological injuries.
