| Hyperbaric Oxygen Therapy (HBOT) |
| |
| Hyperbaric Oxygen (HBO) Therapy is the breathing of 100 % oxygen
while inside a treatment chamber, at a pressure higher than sea level
pressure (ie, greater than 1 atmosphere absolute; ATA). The treatment
may be carried out in a monoplace chamber. The chamber accommodates
a single patient and the entire chamber is pressurized with 100 %
oxygen, which the patient breathes directly. By providing pure oxygen
in a pressurized chamber we are able to deliver 10 – 15 times
more oxygen then if delivered at sea level or at normal atmospheric
levels. Some of the effects this has are to promote the growth of
new blood vessels, decreases swelling and inflammation, deactivates
toxins, increase the body’s ability to fight infections, clears
out toxins and metabolic waste products, and improve the rate of healing.
HBOT should be used to compliment conventional therapies and treatments. |

| Benefits of HBOT: |
| |
1. HBOT is very cost effective.
2. HBOT is non-invasive.
3. HBOT is safe.
4. HBOT works well with other treatments. |

| What is a hyperbaric chamber ? |
| |
It
is a container / vessel / room built to withstand an increased internal
pressure. They are generally cylindrical, spherical or rectangular.
Multiplace chambers are usually constructed in steel and monoplace
units are mainly acrylic. Multiplace chambers have port-holes or small
windows and comfortable seating is provided.
Our large rectangular chamber is approximately 6m x 3m x 2m and is
our main treatment room. Access is via a door which is large enough
to walk through or wheel a special hyperbaric trolley. It has a toilet
available for urgent use. Out smaller chamber is cylindrical measuring
3m long x 2 m diameter and is usually reserved for acute diving-related
injuries.
Both chambers are twin-lock units, which enable personnel to enter
or leave while the main treatment continues. |
| |
| How does HBOT work ? |
| |
| The air we breathe is 21% oxygen, 79% nitrogen and minor amounts
of other gases. Out bodies are usually able to heal themselves with
a normal oxygen level, but in certain conditions extra oxygen is required.
During HBO therapy, the pressure is increased to 2 – 3 times
that of sea-level and you breathe 100% oxygen. The breathing of pure
oxygen under pressure causes a much larger than normal amount of oxygen
to be dissolved in the blood and, subsequently, the rest of the body.
The extra oxygen is used by the body in many ways. Depending on
the underlying problem, the actions can include improved wound healing
by reduction of swelling, infection control and the stimulation
of new blood vessel growth. In dysbaric injuries, there is a reduction
in gas bubble size and a reduction in the body’s response
to that injury.

| |
| Are there any side effects? |
| |
| Side effects are uncommon. They relate to the increase
in pressure (ear or lung barotrauma) or the use of increased amounts
of oxygen (CNS or lung oxygen toxicity). Some patients may also experience
visual changes that cause them to become more near-sighted (myopia);
this is usually temporary and should disappear within 3-4 months of
ceasing therapy. Your doctor will discuss these prior to your commencing
treatment and at any time you are concerned. If at any time during
the treatment you feel uncomfortable or have any sensation that
is not normal for you, please report it to nurse , immediately.
At the end of the treatment, the chamber pressure is reduced to
usual atmospheric pressure end the air will feel colder. You will
feel your ears “popping” during the phase. |
| |
| How long is a hyperbaric treatment ? |
| |
| Except for decompression sickness and arterial gas embolism, the
typical treatments are approximately two hours long. Treatments are
administered on an in-patient or out-patient basis. In some acute
cases, treatments may be administered every eight to twelve hours. |
| |
| How many treatments are needed ? |
| |
| A patient’s clinical response and other factors often dictate
the number of treatments required. Emergency cases, such as carbon
monoxide poisoning, arterial gas embolism or decompression sickness,
may only require one or two treatments. Non-healing wounds may call
for as many as 20 to 30 treatments. |
| |
| What does a hyperbaric treatment feel like ? |
| |
| Generally, the patient will not feel differently. However, during
certain parts of the treatment, the patient may experience a sensation
of fullness in the ears, similar to the feeling experienced on an
airplane. This is a result of the eardrum responding to pressures
changes. Prior to treatment, the patient will be taught a few easy
methods to “clear” his or her ears to avoid discomfort. |
| |
| What can I do during the treatment? |
| |
| It is possible to read, talk, rest, sleep or play cards or other
games with the other patients or staff. There will be a short break
during the treatment when it may be possible to have some refreshment. |
