What to Know Before Receiving Hyperbaric Oxygen Therapy

Hyperbaric Oxygen Therapy (HBOT) is a non-invasive treatment that delivers pure oxygen in a pressurised chamber, boosting the body’s natural healing processes. While it’s increasingly popular for conditions ranging from chronic wounds to skin rejuvenation and anti-ageing, it’s important to be well-informed before starting HBOT. Here’s what you need to know to ensure the treatment is safe and effective for you.

How Does This Treatment Work?

Hyperbaric oxygen therapy allows an increased concentration of oxygen, above that which is possible with inhaled oxygen alone. This is achieved by the delivery of 100% oxygen through a patient mask with the addition of pressure (hyperbaric). This allows oxygen to dissolve directly in the blood plasma as well as saturate the body’s red blood cells.

Preparation Factors to Do Before Your Appointment

Before your session, it is recommended that you have a healthy meal or snack; this can be consumed a few hours before your session. Avoiding alcohol and smoking will help to improve the benefits gained from the session

Potential Benefits

People seek HBOT for a variety of reasons, including:

• Faster recovery from sports injuries
• Enhanced wound healing (e.g., diabetic ulcers, radiation injuries)
• Skin rejuvenation and anti-ageing
• Reducing inflammation and swelling
• Boosting immune function
• Improved cognitive function in some cases (e.g., traumatic brain injuries)

The Treatment Process: What to Expect

• Sessions typically last 60 to 90 minutes. Depending on your condition, you might need multiple sessions—sometimes dozens over weeks or months.
• You’ll be in a pressurised chamber. Some facilities use monoplace chambers (single person) or multiplace chambers (several people).
• You might feel pressure changes. Much like taking off or landing in an aeroplane, you may experience ear pressure, which can be managed by swallowing, yawning, or chewing gum.
• Relaxation is key. Many people nap or listen to music during their sessions.

Do Not Arrive Sick

High temperatures or marked sinus congestion can increase the risk of side effects of hyperbaric oxygen therapy, and further sessions should be delayed until they have resolved. Uncontrolled high blood pressure should also be managed before having any hyperbaric oxygen sessions.

Who Should Avoid or Be Cautious with HBOT?

Certain conditions may require careful evaluation before starting HBOT:

• Lung issues such as pneumothorax (collapsed lung)
• Upper respiratory infections or sinus problems (can increase pressure discomfort)
• Seizure disorders
• Fever or acute illness
• Pregnancy (HBOT is not commonly recommended unless medically necessary)
• Certain types of ear surgery or eardrum issues

Certain medications should be Avoided Beforehand

Certain medications are not safe to be taken alongside hyperbaric oxygen therapy. These include some chemotherapies, some topical treatments and some medications used in the treatment of alcohol addiction.

It is important to bring a full list of medications with you to the appointment so they can be checked with the doctor before you have your session.

Be sure to speak with your doctor and health care providers in advance to discuss any drugs or medications that you are taking.

Food and Drink

It is important to be well-hydrated before attending your session. It is also important to avoid alcohol consumption before treatment and limit or avoid carbonated drinks. Smoking should be avoided both before and after treatments, as it can negate the benefit of oxygen therapy

Wear Cotton Material Clothing

Cotton fibres do not cause static charge accumulation, which can lead to sparks in an oxygen-rich environment. Metal jewellery should not be worn in the chamber for this same reason.
