What’s the difference between Hard and Soft Hyperbaric Chambers?

Learn which type of hyperbaric oxygen therapy chamber is right for you


Before you begin hyperbaric oxygen therapy, it’s important to understand the different types of treatment available. At Hyperbaric Healing Treatment Center, we’re committed to giving you all the information you need to make an informed decision before you begin your healing journey.


How can Hyperbaric Oxygen Therapy help?

Hyperbaric oxygen therapy (HBOT) works by exposing the body to an atmosphere of 100% oxygen, in an enclosed chamber where the atmospheric pressure is increased and controlled.


The benefits of HBOT are well-documented, including:

  • Speeding up the body’s healing by increasing tissue oxygen levels in areas of injury or illness
  • Supporting faster wound healing
  • Reducing swelling that may occur around damaged areas
  • Stimulating new blood vessel growth and increased blood flow
  • Elevating the body’s natural immune defenses to fight infection and bacteria
  • Boosting your supply of circulating stem cells.

What you might not know is that there are different types of hyperbaric chambers, and the health benefits they can offer vary greatly.

What is a Soft Hyperbaric Chamber?

Also known as mild hyperbaric chambers or portable hyperbaric chambers, these inflatable bag chambers cannot achieve internal pressures of over 1.3 atmospheres.


Scientific studies of the effectiveness of HBOT are only conducted at pressures starting at 1.5 atmospheres, so the health benefits of these soft hyperbaric chambers cannot be accurately measured.


Soft hyperbaric chambers are authorized by the FDA only for the treatment of acute mountain sickness. It’s currently not known whether these types of chambers can help with other medical conditions.

What is a Hard Hyperbaric Chamber?

Hard hyperbaric chambers are capable of reaching much higher pressures than soft hyperbaric chambers.


There are two types:


Monoplace hyperbaric chambers are built to fit one patient at a time. They are gradually pressurized and filled with pure oxygen while the patient lies down and relaxes. Monoplace chambers can pressurize up to 3.0 atmospheres.


Multiplace hyperbaric chambers are larger hyperbaric chambers the size of a room that can fit multiple patients at one time. Multiplace chambers are filled with room air while a patient breathes oxygen through a hood or a mask. These chambers are typically found in hospitals and are most commonly used more in emergency situations.


Hard hyperbaric chambers are approved by the FDA to treat many medical conditions. Additionally, HBOT is approved by Medicare to treat the following conditions:

  • Air or Gas Embolism
  • Carbon Monoxide Poisoning
  • Chronic Osteomyelitis
  • Compartment Syndrome/Crush Injury/Other Traumatic Ischemias
  • Compromised Skin Grafts and Flaps
  • Decompression Sickness (Bends)
  • Diabetic and Selected Wounds
  • Exceptional Blood Loss (Anemia)
  • Gas Gangrene
  • Intracranial Abscess
  • Necrotizing Soft Tissue Infection
  • Osteoradionecrosis and Radiation Tissue Damage
  • Thermal Burns


HBOT administered in hard hyperbaric chambers can also help with the following off-label conditions:

  • Fibromyalgia
  • Lyme Disease
  • Migraine
  • Multiple Sclerosis
  • Near Drowning
  • PTSD
  • Recovery from Plastic Surgery
  • Sports Injuries
  • Stroke
  • Traumatic Brain Injury
  • Addiction
  • Autism
  • Anoxic Brain Injury
  • Avascular Necrosis
  • Cerebral Palsy
  • Crohn’s Disease
  • Circulation conditions
  • Concussion
  • Complex Regional Pain Syndrome



soft hyperbaric chambers-our hard hyperbaric chambers

At Hyperbaric Healing Treatment Center, we have four Sechrist 3600 monoplace hyperbaric chambers, capable of pressures up to 3.0 atmospheres. We are proud to treat patients for a variety of insurance-approved and off-label medical conditions.


Our chambers are made of clear acrylic, allowing the patient to see outside the chamber and allowing our trained technologists to closely monitor them at all times. Patients are able to communicate with the attending technologist via an intercom system. To ensure the comfort of our patients, all chambers have privacy curtains between them. Our chambers are also equipped with streaming capabilities, so you can relax and watch a movie or TV show during treatment.
