4. Introduction
Hyperbaric Oxygen Therapy (HBOT) is a
means of providing additional oxygen to
body tissues, by intermittently increasing
the amount of oxygen in the tissues,
thereby enhancing the healing process.
The therapy is painless and has the
potential for good results for certain
medical conditions

6. Definition
Hyperbaric oxygen therapy (HBOT)
is an inhalation of 100% oxygen at
pressure greater than atmospheric
pressure.
abychackothomas@icloud.com
12. HOW DOES HYPERBARIC OXYGEN
THERAPY WORK?
'Hyper' means increased and 'baric' relates to pressure.
Oxygen makes up 21% of the atmosphere air that we
breathe.
During HBO the patient breathes 100% oxygen
intermittently, usually through a hood or mask, while
inside a pressurised chamber.

13. Breathing 100% oxygen under pressure causes
oxygen to be dissolved into plasma.
By intermittently increasing the amount of oxygen
in the tissues, the healing process is enhanced.
HBO can encourage new growth of capillaries,
increases the ability of the body to fight infection
and kill bacteria, and can reduce swelling as well as
other effects.

16. Types of HBOT
Monoplace
Monoplace
chambers are
designed to treat a
single person
pressurized with
100% oxygen.
Multiplace
Multiplace chambers
are designed to hold
several people at
one time and oxygen
is delivered through
a mask, head hood
or endotracheal
tube.

21. Side Effects
Barotrauma to the ears and sinuses caused by
the change in pressure.
Oxygen Toxicity (Rare case)
Changes in vision: this can occur as a result of
multiple treatments

22. Patient Preparation
Educate the Patient about the benefits and side effects of
HBOT
Provide psychological support if he/she is anxious
Check RBS (should be more than 10mmol/L) and vital signs
prior to therapy
Patient must wear clean cotton(100%) clothing inside the
chamber.
The technician needs to know if any medications, including
non-prescription drugs, are being taken by the patient,
Teach the techniques for adequate clearing of the ears
(Valsalva maneuver)

23. Avoid cosmetics, perfumes, hair preparations,
deodorants, or jewellery in the chamber.

Hearing aids, Fountain Pens, Hard Contact lenses,
Heat Pads, Hand Warmers Metal-Framed Spectacles

25. Techniques for adequate clearing of the
ears
As soon as the air flows into the chamber
patient need to start making ears ‘pop’.
The easiest method of clearing the ears is to
try to very gently blow through nose while
holding the nose and lips tightly closed,
Moving lower jaw from side to side or an in or
out motion

26. Nurses Responsibilities
Maintain checklist for oxygen supply and air
cylinder
Verify the written consent form during each
session
Prepare patient trolley with 100% cotton bed
sheets and gown
Make sure of emergency breathing apparatus
Make sure the microphone is properly working
inside and outside the chamber
Observe patient safety measures strictly before
entering the chamberabychackothomas@icloud.com
27. Nurses Responsibilities
Start the session under the supervision of doctor and
record patient data including past medications
Observe the patient for any discomfort before and
during session
Record the data in nursing notes with date and time
Observe the patient for any complications like
hypoglycaemia, giddiness after the session
Close the chamber after proper cleaning
