Other Indications
Indications that HBO can help with but we don't routinely treat at DDRC
Burn injuries have low oxygen levels and can take a long time to heal. Use of hyperbaric oxygen in patients with burn wounds has been shown to:
- Improve healing
- Reduce oedema (swelling)
- Prevent extension of the burn
- Reduce hospital stay
- Reduce need for surgery
- Reduce wound infection
HBO is considered for patients with complex or serious burns therefore each case is assessed on a case by case basis.
Cases that are accepted are often serious but survivable:
- Greater than 20% total body surface area and/or with involvement of the hands, face, feet or perineum.
- Deep partial or full thickness injury.

Carbon monoxide (CO) is a colourless, odourless gas that occurs as a result of incomplete combustion of carbon containing substance. It is less common as safety has improved but can still occur as a result of poorly maintained gas appliances, burning solid fuel inside (log burners) or using barbecues or camping stoves in confined spaces.
The symptoms of carbon monoxide poisoning include:
- Headache - 90%
- Nausea and vomiting - 50%
- Vertigo - 50%
- Alteration in consciousness - 30%
- Weakness - 20%
CO poisoning can also cause longer term nervous system damage and result in problems with dementia, memory and concentration, as well as causing symptoms similar to Parkinson's Disease. Possible longer term effects include mental health problems such as depression.
If you think you have been exposed to carbon monoxide open windows and doors to increase ventilation and attend your nearest Emergency Department. A blood test can be taken to determine if you have carbon monoxide poisoning.
There are very specific circumstances in which HBO may help someone who has carbon monoxide poisoning. HBO can help improve oxygenation of tissues and speed up the elimination of carbon monoxide from the body.
A doctor can refer a patient to a hyperbaric chamber if they fit the following criteria:
- new neurological deficit or mental status change
- carboxyhaemoglobin of greater than 25% at any time
- pregnancy
- ECG evidence of myocardial involvement (evidence of damage to the heart)
- loss of consciousness, even if subsequently recovered

Central Retinal Artery Occlusion is a rare cause of sudden loss of vision. The degree of visual loss is dependent on the exact location and degree of occlusion (blockage of blood supply to the eye).
Hyperbaric oxygen therapy (HBO) can help restore blood supply to the eye however studies have shown that it is only effective if treatment is started within 24 hours of symptom onset.
In practical terms this means that very few patients meet the criteria for HBO and therefore it is a condition that we very rarely treat in the UK.

An intracranial abscess is a closed collection of pus and infection somewhere within the skull.
Hyperbaric Oyxgen Therapy (HBOT) is recognised to be a useful alongside the treatment provided in the hospital, i.e. antibiotics, neurosurgery and possibly intensive care involvement. However this only applies to some patients; it is not offered as standard and each case is carefully reviewed to decide if worthwhile.
Studies have shown better survival rates in those with multiple abscesses, in a deep location in immunocompromised patients and where surgery is contraindicated or there has been failure of standard treatments.

Oxygen is carried around the body by red blood cells, if you lose blood due to trauma or surgery and that blood is not replaced immediately with a blood transfusion you have a reduced supply of oxygen to your heart and brain which can quickly lead to death.
Hyperbaric oxygen can provide oxygen to depleted tissues without the need for a good blood supply and several animal studies have shown strong evidence of this. If a patient is unable to receive blood transfusions for blood loss due to medical or religious reasons then HBO has be used to sustain oxygenation and increase the chance of survival.
However, as these patients are critically unwell and the hyperbaric centres in the UK are not on hospital sites it is very complex to arrange treatment of these patients. HBO also only provides a bridge therapy until the patient is stabilised (i.e. it is not a definitive solution in itself).
Individual referrals are assessed on a case-by-case basis.

Crush Injuries
Crush injuries can cause soft tissue trauma but may also feature open wounds, broken bones, nerve injury, and vascular damage. Surgery can be employed to stabilise fractures and to repair nerves and vessels, but there are no surgical interventions that address tissue damage at the microvascular level. The trauma from the crush injury causes swelling (oedema), reducing the amount of oxygen able to get to the damaged tissues and causing further injury.
HBO has been used to counteract this phenomenon and increase oxygenation to the damaged tissues thus increasing the chance of healing.
Compartment syndrome
Compartment syndrome is a complication of a crush injury where bleeding occurs in the muscle compartment. This compartment is a fixed space and does not expand therefore, if the bleeding continues, the pressure can cause damage to the muscles and nerves. Surgery is used to relieve this pressure before the muscles and nerves die.
In some studies, HBO has been used when compartment pressures were elevated but before surgery was indicated, allowing for recovery before surgery was required. Therefore, in patients where compartment syndrome is a risk but not yet established, the early addition of HBO may be considered.
In both crush injuries and compartment syndrome HBO treatment is decided on a case by case basis.
