1. • Good afternoon

4. Oxygen therapy is a treatment that
delivers oxygen gas for you to
breathe. You can receive oxygen
therapy from tubes resting in your
nose, a face mask, or a tube placed
in your trachea, or windpipe

5. This treatment increases the
amount of oxygen your lungs
receive and deliver to your blood.
Oxygen therapy is key treatment of
respiratory care.

6. Oxygen therapy may be prescribed for you
when you have a condition that causes
your blood oxygen levels to be too low.
Low blood oxygen may make you feel
short of breath, tired, or confused, and
can damage your body.

8. Indication for Oxygen therapy
 Severe respiratory distress (eg. Pneumonia and acute asthma.
 Intra and post operatively
 Hypoxia and hypoxemia
 Myocardial infraction
 Severe trauma
 Shock
 Shortness of breath
 Hypotension
 Preoxygenation

10. TRANSPORT OF OXYGEN
Oxygen is transported from alveoli to
the tissue by blood in two forms:
1. As simple physical solution
2. In combination with hemoglobin.

11. Gases in arterial and venous blood Gas
Arterial blood Venous blood
Oxygen Arterial blood
Venous Blood
Partial pressure (mm Hg) 95
40
Content (mL%) 19
14
Carbon dioxide
Partial pressure (mm Hg) 40
46
Content (mL%) 48
52

12. „AS SIMPLE SOLUTION
Oxygen dissolves in water of
plasma and is transported in this
physical form. Amount of oxygen
transported in this way is very
negligible. It is only 0.3 mL/100 mL
of plasma. It forms only about 3%
of total oxygen in blood

13. It is because of poor solubility of
oxygen in water content of plasma.
Still, transport of oxygen in this form
becomes important during the
conditions like muscular exercise to
meet the excess demand of oxygen
by the tissues.

14. „IN COMBINATION WITH
HEMOGLOBIN
Oxygen combines with hemoglobin in
blood and is transported as
oxyhemoglobin. Transport of oxygen in
this form is important because,
maximum amount (97%) of oxygen is
transported by this method.

15. Oxygen Carrying Capacity of
Hemoglobin
Oxygen carrying capacity of
hemoglobin is the amount of oxygen
transported by 1 gram of hemoglobin.
It is 1.34 mL/g.

16. Oxygen Carrying Capacity of Blood
Oxygen carrying capacity of
blood refers to the amount
of oxygen transported by
blood. Normal hemoglobin
content in blood is 15 g%.

17. Since oxygen carrying capacity of
hemoglobin is 1.34 mL/g, blood
with 15 g% of hemoglobin should
carry 20.1 mL% of oxygen.
i.e. 20.1 mL of oxygen in 100 mL
of blood.

18. Caution of oxygen therapy
• Oxygen toxicity- can occurs if FIO2
increase 50% longer then 48 hrs.
• Danger of fire
• infection

19. Oxygen toxicity
• Oxygen toxicity is a condition resulting
from the harmful effects of breathing
molecular oxygen (O2) at increased
partial pressures. Severe cases can
result in cell damage and death, with
effects most often seen in the central
nervous system, lungs, and eyes.

20. • The result of breathing increased
partial pressures of oxygen
is hyperoxia, an excess of oxygen in
body tissues. The result of breathing
increased partial pressures of oxygen
is hyperoxia, an excess of oxygen in
body tissues.

21. Sign and symptoms of oxygen toxicity
• Cough
• Nausea and vomiting
• Substernal chest pain
• Fatigue
• Headache
• Dyspnea
• Inspiration pain

22. Safety Precautions for Using Oxygen
Therapy
The following list includes at-home oxygen
therapy safety DON’Ts:
• Do not go near open flames - Stay least
10 feet away from open flames while
using an oxygen concentrator or oxygen
tank (cigarettes, candles, gas stoves,
etc.).

23. • Do not use an electric razor
while using oxygen
therapy (they are known to put
off sparks).
• Do not use oil or petroleum-
based products while using
oxygen.

24. The following list contains at-home
oxygen therapy safety DOs:
• Keep oxygen cylinders secure at all
times. If they fall over, the valve can
come loose, and the pressurized
oxygen will turn the tank into a
dangerous missile.
• Place a non-smoking sign in your
home or one in each room.

25. • Notify your utility providers and
local fire department that you are
using oxygen in your home. They
can put you on a “top-priority list”
in case you lose power.

26. • Keep the service number for your
oxygen equipment nearby, in case
something breaks.
• Make sure your smoke detectors are
all working correctly and replace
them with new batteries as soon as
they start to get low.

27. • When not in use, store your
oxygen equipment in an area of
your house that is away from
any sources of heat.

28. Equipment of oxygen therapy
• Nasal cannula
• Face Mask
• Partial rebreathing mask
• Non rebreathing mask
• Venturi mask
• T – piece
• ET Tube
• Tracheostomy tube

29. Nasal cannula

30. Nasal cannula
 It is a disposable .
It is a plastic devise with two open prongs for
insertion into nostrils, connected to an oxygen
source.
Used for low medium concentration of oxygen
(24-44%).

31. Flow of nasal cannula
Liter Percentage
1 liter/ min 24%
2 liter/ min 28%
3 liter/ min 32%
4 liter/ min 36%
5 liter/ min 40%
6 liter/ min 44%

32. Advantage of nasal cannula
• Easily used in home setting.
• Client able to talk and eat with oxygen in
place.
Disadvantage of nasal cannula
• May cause irritation the nasal and pharyngeal
mucosa.
• Never deliver more then 2-3 liter/ min to client with
chronic lungs disease.

33. Types of face mask
The simple oxygen mask.
The partial rebreathing mask.
The non rebreathing mask.
The venturi mask

34. The simple oxygen mask
 simple mask is made of
clear, flexible, plastic or
rubber that can be molded
to fit the face.
 it delivers 35- 60% oxygen.
A flow rate of 6 to 10 liter/min.

35. Documentation
Date and time oxygen started.
Method of delivery.
Oxygen consentration and flow rate.
Pt. observation.
Add oronasal care to the nursing
care plan.
