Hyperbaric Oxygen Therapy Education

HBOT Basics, Safety & Chamber Types

Hyperbaric Oxygen Therapy (HBOT) involves breathing oxygen in a pressurized environment to increase oxygen delivery throughout the body. Used across hospital-based and outpatient settings, HBOT plays a role in the treatment of select complex medical conditions involving tissue hypoxia, impaired healing, infection, and radiation injury.

House of Hyperbaric provides physician-focused educational resources designed to support a better understanding of hyperbaric medicine, clinical applications, treatment environments, and operational considerations.

Hyperbaric Oxygen Therapy is a medical treatment in which a patient breathes oxygen while inside a pressurized chamber.

Under increased atmospheric pressure:

  • Oxygen dissolves more efficiently into plasma
  • Tissue oxygen delivery increases
  • Hypoxic tissues may receive improved oxygenation
  • Certain healing and physiologic processes may be supported

HBOT is commonly incorporated into multidisciplinary treatment plans involving wound care, surgery, infectious disease management, vascular medicine, rehabilitation, and radiation injury care.

How Hyperbaric Oxygen Therapy Works

During HBOT treatment, atmospheric pressure inside the chamber is increased above normal sea-level pressure. This process allows oxygen to dissolve into plasma at significantly higher concentrations than under normal conditions.

Potential physiologic effects may include:

  • Enhanced tissue oxygenation
  • Support for angiogenesis
  • Reduction of edema
  • Improved leukocyte function
  • Support for compromised tissue healing

These programs are commonly found in:

  • Hospitals
  • Wound care centers
  • Accredited hyperbaric facilities
  • Specialty outpatient programs

Types of Hyperbaric Chambers

Hyperbaric centers will soon be able to submit their location for inclusion in the House of Hyperbaric directory.

Monoplace Chambers

Monoplace chambers are designed for a single patient and are commonly pressurized with 100% oxygen.

Characteristics may include:

  • Individual treatment environment
  • Acrylic chamber design
  • Hospital and outpatient use
  • Physician-supervised treatment protocols

Multiplace Chambers

Multiplace chambers accommodate multiple patients simultaneously and are typically pressurized with compressed air while patients breathe oxygen through masks or hoods.

Common features include:

  • Hospital-based systems
  • Critical care capability
  • Clinical staff entry during treatment
  • Support for more complex patient management

Mild Hyperbaric vs Medical-Grade Hyperbaric Therapy

Medical-grade Hyperbaric Oxygen Therapy (HBOT) is a physician-supervised medical treatment delivered using FDA-cleared hyperbaric chambers, regulated oxygen delivery systems, and established clinical protocols. These treatments are performed at substantially higher therapeutic pressures and are integrated into comprehensive medical programs designed to manage recognized clinical conditions such as radiation tissue injury, diabetic foot ulcers, decompression sickness, compromised grafts and flaps, and other UHMS-recognized indications. Medical-grade HBOT programs operate within structured healthcare environments including hospitals, wound care centers, accredited hyperbaric facilities, and specialty outpatient programs, where patient screening, treatment protocols, safety standards, emergency procedures, and clinical oversight are strictly maintained.

In contrast, mild hyperbaric therapy generally refers to lower-pressure chamber systems frequently marketed for wellness, recovery, athletic performance, or non-medical applications. These systems operate at significantly lower pressures, often utilize different oxygen delivery approaches, and are not equivalent to hospital-based medical hyperbaric programs. Mild hyperbaric systems do not provide the same therapeutic environment, clinical oversight, or standardized treatment protocols associated with medical-grade HBOT and should not be confused with the evidence-based hyperbaric treatments used for recognized medical indications within accredited clinical settings.
