Initial HBOT instructions Mar 20th, 2024
Since hyperbaric oxygen therapy requires a pressure higher than the normal atmospheric pressure, this creates tension in the tissues that may be inappropriate for people with some medical conditions.


People with the following conditions should not use HBOT treatment:

  • Fear of enclosed space

  • Pneumothorax

  • COPD- Chronic Obstructive Pulmonary Disease

  • History of burst lung

  • Emphysema

  • Severe asthma

  • History of seizures (fits)

  • Heart disease

  • Eye, ear, nose and throat problems

  • Experienced middle ear barotrauma

  • Eustachian Tube Dysfunction

  • High fever or acute illness

  • Latex allergy

  • Currently pregnant

  • History of chest surgery

  • History of heart failure

People with an implanted electronic medical device such as a pacemaker/automatic implantable cardioverter-defibrillator (AICD) should not enter HBOT units.

People with a history of exposure to, or taking the following medications should not enter HBOT units.

  • Doxorubicin (Adriamycin)

  • Cisplatin

  • Disulfiram (Antabuse)

  • Mafenide Acetate (Sulfamylon)

  • Bleomycin

Before coming for your appointment

Do not put on any oil or alcohol based grooming products such as perfume, or makeup.

Bring a towel or blanket for comfort, and a book or a tablet for entertainment!

Set aside at least 90 minutes for the HBOT session.


Before entering the HBOT

Do not carry any items into the HBOT that could ignite a fire (eg. lighters, match sticks, etc.).

Remove and do not bring in any sharp objects, be careful with jewellery, into the HBOT.

Make sure you take a visit to the toilet prior to entering. To get the most out of your HBOT session ideally you should not leave the unit for 60 minutes!


During compression (5 minutes)

Once you are comfortable inside the HBOT, we will begin slow compression. The feeling is similar to descending from a plane flight. Your ears ‘pop’ as the atmospheric pressure is increased. This is where the Valsalva maneuver or swallowing saliva, could be performed to ease and equalize pressure changes within your ears.

Once pressurised the door will not open from the inside.

We will maintain verbal communication via intercom or phone during pressurisation.

At any point of time when discomfort is experienced, we can slow or halt compression and open the door until you are ready to proceed. It is perfectly normal and we will be there to help.


Treatment time (40-50 minutes)

Once the pressure stabilizes, you can get comfortable and enjoy the high pressured high oxygen concentration environment.

This is where you can relax, read a book, play a game of tetris, sleep, meditate, conduct breathing exercises, or even catch up on your favourite podcast.


Decompression (10 mins)

At the end of your HBOT session the unit will slowly decompress automatically to allow a safe exit.

The pressure will be released slowly until you are back to 1 atmosphere.

You can exit the HBOT with or without support. Again, we will be there for you!



Once you are out, let us know how things went and what changes you would like ot make for future HBOT sessions.
