Hyperbaric Oxygen Therapy (HBOT) is a sophisticated treatment modality that involves breathing pure oxygen in a pressurized chamber. This scientifically-backed therapy has been utilized for decades to treat a variety of conditions, from decompression sickness to chronic wounds and more. At Under Pressure Hyperbarics, we delve deep into the science behind HBOT to help our patients understand how increased oxygen levels can lead to significant therapeutic outcomes. This blog explores the biological effects of HBOT, providing insights into why this therapy is so effective.

The Basics of HBOT

HBOT involves administering 100% oxygen at pressures greater than atmospheric sea level pressure. Typically, these treatments occur in a specialized chamber where the air pressure is increased to up to three times higher than normal air pressure. Under these conditions, your lungs can gather more oxygen than possible by breathing pure oxygen at normal air pressure.

Critical Biological Effects of HBOT

Enhanced Oxygen Saturation and Dissolution: Under normal conditions, oxygen is primarily transported throughout the body bound to hemoglobin in red blood cells. However, under the increased pressure of HBOT, oxygen can also dissolve into the body’s fluids, such as plasma, cerebrospinal fluid, and lymph, allowing it to reach areas where circulation is diminished or blocked. This process facilitates greater oxygen delivery to ischemic tissues, areas with reduced blood flow.
Neovascularization: One of HBOT’s pivotal benefits is its ability to stimulate the growth of new blood vessels, a process known as neovascularization. This is particularly important in areas with reduced blood circulation and in tissues damaged by injury or disease. By promoting neovascularization, HBOT enhances blood supply to these areas, improving oxygen and nutrient delivery, which supports faster and more effective healing.
Anti-inflammatory Effects: HBOT has been shown to significantly reduce inflammation by modulating the levels of cytokines proteins involved in signaling inflammation. By decreasing pro-inflammatory cytokines and increasing anti-inflammatory cytokines, HBOT helps mitigate inflammatory processes at injury sites, aiding in pain reduction and faster recovery.
Antimicrobial Activity: High oxygen levels under pressure have a bactericidal and bacteriostatic effect on anaerobic bacteria, which thrive in environments devoid of oxygen. Additionally, HBOT enhances the ability of white blood cells to fight infection, further bolstering the body’s innate immune response.
Enhanced Collagen Production: Collagen is a vital protein for wound healing, as it helps form scar tissue to repair and strengthen the damaged area. HBOT promotes collagen synthesis, thereby enhancing the structural integrity of newly formed tissues during the healing process.

Therapeutic Applications of HBOT

Given its wide range of biological effects, HBOT is employed in the treatment of several conditions, including:

Decompression Sickness: This condition, also known as “the bends,” affects divers who surface too quickly. HBOT can counteract the effects of decompression by normalizing air pressure and dissolving gas bubbles that form in the bloodstream.
Chronic Wounds: Conditions such as diabetic foot ulcers and venous stasis ulcers benefit from HBOT due to its ability to enhance oxygenation and neovascularization in hypoxic wound tissues.
Infections: Particularly those involving anaerobic bacteria, which can be effectively managed with HBOT due to its oxygen-enriched environment hostile to anaerobes.
Neurological Conditions: Emerging evidence suggests HBOT’s efficacy in treating conditions like stroke and traumatic brain injury, where increased oxygenation can help revive function in dormant brain cells.
