Hyperbaric Chamber Access: Are All Hospitals Equipped?

Hyperbaric oxygen therapy is a treatment that uses a pressurised chamber to increase the amount of oxygen in the blood, helping to heal traumatic injuries and wounds that have not healed with other treatments. While hyperbaric oxygen therapy is offered by an estimated 1,800 to 2,000 hospitals in the US, not every hospital has a hyperbaric chamber. In fact, fewer than 10% of hyperbaric facilities in the US will accept emergency patients requiring hyperbaric oxygen therapy.

Hyperbaric oxygen therapy is used to treat chronic wounds, diabetic foot ulcers, bone infections, and more

Hyperbaric oxygen therapy is a medical treatment that involves breathing 100% pure oxygen inside a pressurised chamber. The pressure inside the chamber is about two and a half times higher than normal air pressure, which helps the lungs gather and absorb more oxygen. This increased oxygen in the blood helps to heal damaged tissue and promote the growth of new blood vessels, skin, and connective tissues.

Hyperbaric oxygen therapy is used to treat chronic wounds, particularly those that have failed to heal with other treatments. It is often used for diabetic foot ulcers, which can become seriously infected and lead to amputation. The therapy increases the effects of antibiotics and activates white blood cells to fight infections. It is also used to treat bone infections (osteomyelitis) that have not improved with other treatments and can help prevent amputation in patients with bone infections.

In addition to treating wounds and infections, hyperbaric oxygen therapy is used for a range of other conditions. It can be used to treat radiation injuries, burns, carbon monoxide poisoning, and compromised skin grafts. It is also beneficial for patients with chronic bone and soft tissue damage caused by radiation treatment for cancer. Hyperbaric oxygen therapy can help heal traumatic injuries, such as crush injuries, and can be used for conditions such as lymphoedema, minor burns, vascular leg wounds, head and neck injuries, and tooth extractions.

While hyperbaric oxygen therapy offers many benefits, it is not a cure-all. It should not be used during pregnancy as it can cause constriction of blood vessels in the placenta, leading to low oxygen levels in the fetus. It is also important to consult a healthcare provider before undergoing this treatment, as side effects may include ear injuries, claustrophobia, and sinus congestion and pressure.

Hospitals with 24-hour emergency hyperbaric facilities are limited

Hyperbaric oxygen therapy (HBOT) is a medical treatment that uses a special pressure chamber to increase the amount of oxygen in the blood. This therapy can be used to treat a variety of conditions, including chronic wounds, diabetic foot ulcers, bone infections, burns, and carbon monoxide poisoning. While HBOT is offered by many hospitals and outpatient centers, the availability of 24-hour emergency hyperbaric facilities is limited.

There are approximately 1,300 to 2,000 hyperbaric treatment facilities in the United States, each with one or more hyperbaric chambers. However, fewer than 10% of these facilities offer emergency HBO2 treatment, and some only do so intermittently. This limited availability is due to several factors, including funding and staffing considerations, as well as concerns about legal liability. Providing emergency HBOT services is more expensive due to the specialized training and staffing required, and the risk of liability is also increased.

In the past, hospitals and other hyperbaric treatment facilities provided 24/7 access to emergent HBOT as a public service. However, today, most hyperbaric chambers decline to accept emergent patients. This has led to delays in treatment and poorer patient outcomes. Organizations such as the Undersea and Hyperbaric Medical Society have recognized this deficiency in US healthcare and have advocated for change.

To increase access to emergency HBOT, incentives are needed to encourage hyperbaric treatment facilities to offer this service. This could include direct federal or state grants, indemnification from legal liability, and favorable reimbursement considerations from Medicare, Medicaid, and private insurance companies. Additionally, more physicians need to be trained in hyperbaric fellowship programs approved by the Accreditation Council for Graduate Medical Education.

While the availability of 24-hour emergency hyperbaric facilities is currently limited, efforts are being made to improve access to this lifesaving treatment. With the right strategies and support, more patients will be able to receive the urgent care they need.

The Undersea and Hyperbaric Medical Society provides location information for hyperbaric chambers in North and Central America

Hyperbaric oxygen therapy is a treatment method that uses a special pressure chamber to increase the amount of oxygen in the blood. This helps the blood carry more oxygen to organs and tissues in the body, promoting the growth of new blood vessels and accelerating the healing of wounds, particularly infected wounds. It is often used to treat chronic wounds, diabetic foot ulcers, bone infections, burns, carbon monoxide poisoning, and compromised skin grafts.

While not every hospital has a hyperbaric chamber, they are available in a variety of settings, including hospitals, doctors' offices, private clinics, and business occupancies. In North and Central America, the Undersea and Hyperbaric Medical Society (UHMS) provides location information for hyperbaric chambers. The UHMS is an international non-profit organization serving members from over 67 countries. It is the primary source of scientific information for diving and hyperbaric medicine physiology worldwide and supports research on matters of hyperbaric medicine and physiology.

The UHMS website includes a chamber directory that provides the public with location information on hyperbaric chambers within North and Central America. This directory includes a list of UHMS-accredited hyperbaric chamber facilities. UHMS accreditation signifies that a facility has met rigorous standards for patient care and safety, including evaluations of the facility, equipment, staff, and training.

In addition to providing location information, the UHMS also offers a certificate of added qualification (CAQ) for physicians who have completed the necessary training in hyperbaric medicine. This training is available through a postgraduate medical fellowship approved by the Accreditation Council for Graduate Medical Education (ACGME) and other organizations. The UHMS also maintains the Charles W. Shilling Library, the largest repository of current and historical research and clinical information in the field of diving and hyperbaric medicine.

Hyperbaric chambers are also used in support of civilian and military diving operations

Hyperbaric chambers are an essential tool in the treatment of decompression sickness, also known as "the bends", which is a common risk in both civilian and military diving operations. The condition occurs when nitrogen or inert gas bubbles form in the bloodstream and tissues due to rapid changes in pressure during ascent or descent. Hyperbaric chambers provide a controlled environment where the pressure can be gradually reduced to safely eliminate excess gases from the body, thereby reducing the size of the bubbles and treating decompression sickness effectively. This treatment is usually carried out in Class A and B chambers, which are pressurized with 100% oxygen and can also treat other clinical indications.

The use of hyperbaric chambers in diving operations is particularly valuable in military diving, where operational constraints may prevent divers from completing decompression stops before surfacing. This increases the risk of decompression sickness. Military diving operations are often conducted in remote locations under difficult and changeable conditions, requiring lightweight and reliable hyperbaric chamber solutions that can be easily transported and operated. Companies like SOS Group Global have designed lightweight hyperbaric chambers, such as the Hyperlite SL3 and DL5, to meet these needs and facilitate rapid response for military divers suffering from pressure-related injuries.

Hyperbaric chambers also play a crucial role in supporting civilian divers. They are used to treat gas embolisms, which occur when air bubbles enter the bloodstream due to rapid ascents or lung barotrauma. Hyperbaric oxygen therapy helps shrink these bubbles, promoting their reabsorption and reducing the risk of blockages and tissue damage. Additionally, hyperbaric oxygen therapy accelerates wound healing by delivering higher concentrations of oxygen to injured tissues, promoting the growth of new blood vessels, and enhancing the body's ability to fight infections.

Beyond their use in treating dive injuries, hyperbaric chambers are invaluable for training purposes. They allow divers to simulate dives in a controlled environment, helping them understand how their bodies react to changes in pressure. This hands-on experience is vital for new divers to learn their limits and prepare for various scenarios they may encounter underwater. Furthermore, hyperbaric chambers support research and advancements in diving knowledge and equipment. Researchers use these chambers to test new diving gear, such as rebreathers and dive computers, under controlled conditions, contributing to the overall safety and progress of civilian and military diving operations.

Some patients believe hyperbaric oxygen therapy can cure cancer, Parkinson's, and Alzheimer's, but these are non-evidence-based uses

Hyperbaric oxygen therapy (HBOT) is a treatment that uses a special pressure chamber to increase the amount of oxygen in the blood. While it is well-known for treating scuba and deep-sea divers affected by rapid pressure changes, it is also used to treat a variety of health problems. These include carbon monoxide poisoning, diabetic foot ulcers, chronic wounds, bone infections, and burns. The therapy can also help wounds, especially infected wounds, heal more quickly.

While HBOT is a powerful tool, it is not a cure-all. Some patients mistakenly believe that HBOT can cure cancer, Parkinson's disease, and Alzheimer's disease. However, these are non-evidence-based uses for HBOT, and the therapy has not been proven to treat these conditions. The U.S. Food and Drug Administration (FDA) recommends that individuals consult their healthcare provider before using HBOT to ensure they are pursuing the most appropriate care. If HBOT is recommended, the FDA advises individuals to go to a hospital or facility that has been inspected and accredited by the Undersea and Hyperbaric Medical Society.

While HBOT has not been proven to cure cancer, it can help people with chronic bone and soft tissue damage caused by radiation treatment. Radiation therapy kills cancer cells but can also damage the tiny blood vessels that feed healthy cells. HBOT can promote the growth of new blood vessels in areas affected by disease, helping to heal this damage.

There is also ongoing research into the potential benefits of HBOT for Alzheimer's disease. Some studies have found that HBOT improved cognitive function in patients with Alzheimer's, while others have investigated the influence of hyperbaric oxygen on oxidative stress markers in the blood and inflammation cytokines. However, other studies have shown limited efficacy in ameliorating the progression of Alzheimer's disease.

In addition to the uses mentioned above, HBOT is being studied for other conditions, including COVID-19. However, it is important to note that as of July 2021, the FDA has only cleared hyperbaric chambers for specific disorders, and serious complications are rare when the chambers are used for these indications.
