Terms & Conditions

Please note all patients will be requested to sign below policies before starting treatment at NUMA. 


Hyperbaric Oxygen Therapy (HBOT) is a painless non-invasive process. You should feel comfortable at all times during your treatment. If you do not, speak to the technician immediately.


If any, the most likely side-effect you may feel during your hyperbaric treatments is the pressure changes which affect your eardrum. Your technician will teach you the valsalva manoeuvre which is a technique that allows you to equalize the pressure in the middle ear and additional techniques which will help you throughout treatment. Any ear pain should be addressed immediately during treatment. Please discuss and notify any problems or concerns you may have with the technician.


Sinus squeeze is very rare and is caused by changes in pressure. Pain may be felt around the sinus areas of the face. This usually occurs if the sinuses are blocked by mucus or tissue. Always inform the technician if you are uncomfortable or feel any pain immediately.

Other risks 

Some mild physiological changes and symptoms may present themselves over the course of your treatments; some may be due to medication interactions. It is important that you advise your technician and physician if any of unfamiliar symptoms arise, including but not limited to: 

  • Nausea. 
  • Changes in vision – temporary changes in eyeglass prescription may occur. These changes may be permanent in about 2% of those patients; usually the change is a vision improvement.
  • Numbness or tingling in the fingers or facial twitching. 
  • Shortness of breath or dizziness. 
  • Restlessness and/or irritability. 
  • Tinnitus (ringing of the ears). 
  • Out of the ordinary physical or mental changes. 
  • Hyperbaric Fatigue Syndrome – fatigue that occurs after treatments.
  • Herxheimer Reaction – for patients with infections, fatigue or an enhancement of symptoms may occur as a reaction to the large number of bacteria being destroyed. 
  • Oxygen Toxicity – in rare situations (1 in 10,000), oxygen toxicity can produce a seizure. The seizure has no lasting effect.

Please notify us immediately if any of the above or any the following occurs during your course of treatment. 

Please call us and reschedule your appointments if you develop colds, flu, upper respiratory infection, sinusitis, high fever, viral infection, vomiting, headache, or any other out-of-the-ordinary symptoms or concerns. 

Please let us know if there is anything we can do, in order to ensure your time with us is comfortable and pleasant. If you have any concerns and/or develop problems with your health, call your GP/physician immediately and please inform us. We are here to help you get better. 


I , _______________________________________________, hereby consent and authorize Numa Ltd staff to administer sessions of Hyperbaric Oxygen Therapy (HBOT) to me at the Hyperbaric Oxygen Clinic (Clinic). In doing so, I hereby fully understand and acknowledge the following:

I have received the approval of assigned medical consultant to receive HBOT. I was explained the possible benefits and risks of HBOT, including as relevant to my specific condition (if applicable). I acknowledge that the physician ultimately responsible for my care is my GP. 

I understand that I am undergoing HBOT not for the purpose of Treatment of disease, disorder or injury. I understand that I am only using HBOT as an aid to improve my general wellbeing and/or assist healing. For this reason, the nature and purposes of HBOT have been explained to me, including the option not to have treatment. 

I understand that for best results a full course of sessions should be completed.

I also understand that HBOT may need to be repeated in the future, either by repeated sets of treatment or by frequent maintenance treatments to help maintain its benefits. 

Prior to any treatment, I have undergone an Initial Consultation and been given the opportunity to ask any questions I have regarding HBOT, and these have all been answered to my satisfaction. I have been informed that I may refuse treatments at any time, or even terminate a treatment whilst in the chamber, and exit the chamber in accordance with the instructions of the chamber operator. 

Before my first treatment, I have informed the Clinic of my current health status, all current medications, and therapies, and I agree that it is my responsibility to keep the Clinic informed of any changes in my medical condition, medication or therapies before each session and I authorize the Clinic to contact my GP and other involved physicians and share my information if necessary. 

I will follow the instructions of the chamber operator and I will inform them of any concerns before and during the treatment, such as pain, nausea, diarrhoea, dizziness, visual changes, ringing or other noises in ears, unusual smells, fear or anxiety reaction, unusual sweating, changes in heart rhythm, hiccups, chest pain, faintness, mood changes, difficulty breathing or any discomfort. 

I understand that the benefits of HBOT may be much greater if I follow a healthy lifestyle, which includes non-smoking, weight control, exercise, proper nutrition and stress management. 

I understand the risks and complications involved with this treatment can include and are not limited to the following: 

Potential Risks of HBOT (more than 5%):

  • Ear drum/ sinus damage, discomfort or pain, due to pressure changes
  • Changes in vision (usually temporary and should return to pre-treatment levels about 6 weeks after treatment) 
  • Confinement anxiety/claustrophobia 
  • Fatigue

Uncommon Risks and Complications of HBOT (1-5%):

  • Sinus pain or tooth pain due to the effects of the pressure changes (pain relief medication may assist with this)
  • Existing cataracts in the eye may accelerate in maturity (this may require the need for a cataract extraction)
  • Patients with epilepsy may require extra medication to reduce the risk of seizures (usually only during treatments) 
  • Oxygen toxicity that may manifest with facial twitching, nausea, ringing ears, visual disturbance, seizures or sign of irritability (in most cases such symptoms can be quickly and simply fixed by taking away the oxygen masks for a few minutes)
  • Lung damage due to the effects of pressure changes (it may require some treatment and possible admission to hospital) 

Rare Risks and Complications (less than 1%):

  • Hearing loss, dizziness, tinnitus (ringing in the ears) and balance problems. If this occurs, you may need some treatment and hospitalization. Sometimes this can be permanent.

I believe the benefits from this treatment, exceed the risks involved. 

No guarantee has been made that the treatment will improve my condition even though it has been carried out with due professional care. If any unforeseen conditions arise during the course of the treatment, I do hereby authorize/request the staff to perform any additional procedures and/or treatments as may be deemed necessary in that time.

General Terms and Conditions

Preparing for Your Hyperbaric Oxygen Therapy

One of our main objectives is to inform you of what to expect during your hyperbaric treatments with us. Prior to any treatment session you will be asked to come in for an initial consultation for an assessment and taken through an orientation. The purpose of this consultation is to make sure you are suitable for HBOT treatment with a medical assessment and to answer any questions you may have. Please feel free to ask any questions, we are here to help you.

Children, family, friends, caretakers 

In order to be able to provide efficient and safe monitoring during your treatment, we don’t allow any family members, friends, caretakers, or any other persons associated with the patient (“Associates”) in the clinic room (unless specifically authorized by a technician). Failure by you or any of your Associates to comply with this requirement or to follow the instructions of a technician when in the clinic room may result in the termination of your treatment for that day.

No child under the age of 14 years old is allowed in the treatment area.

Personal Items

For your safety and the safety of those around the chambers, only items approved by our technical team can be taken into the chamber with you. Each chamber is accommodated with a mattress, pillows and blankets. 

NUMA Ltd and its staff members are not responsible for the loss of any your personal belongings.


We advise loose-fitting cotton clothing, and avoid cosmetics, perfumes, hair sprays, deodorants and jewellery. Shoes must be removed, and socks must be worn inside chamber.

Food and drink 

No food/eating is allowed in the chamber. 

It is strongly recommended that you have a light meal one hour prior to your treatment and are well hydrated with water throughout the day. To obtain full benefit from your treatments, it is recommended that you avoid food and beverages that contain caffeine. Consumptions of coffee, tea and caffeinated drinks should be kept to a minimum during the time you are receiving treatment as caffeine constricts blood vessels. Also, alcoholic beverages should be avoided before treatments because of alcohol’s diuretic effect.


Nicotine greatly compromises the effectiveness of your treatments and increase the risk of seizures. It constricts blood vessels which decreases blood flow to bone and tissue areas, thus slowing down the healing process by approximately thirty percent. Every attempt should be made to quit or temporarily stop smoking. If you must smoke, please do so as long before your treatment and as late after your treatment as possible. 


Every attempt will be made to plan your treatments so that they fit your schedule. Once you have reserved your time slot, we try to keep it reserved for you for the duration of your treatment. If you are late, you are unable to come in, or we have an emergency patient, we may assign your time slot to another patient. Keep in mind that generally, time slots are on a first come first serve basis. 

Please arrive 5 minutes prior to your scheduled treatment time in order to prepare for your treatment. Our daily treatment schedule runs smoothly if patients arrive on time. All appointments will start on time with no exception. If you are late, this time will be deducted from the remainder of your allocated session.
