Oxygen administration is used to treat conditions causing low oxygen levels in the blood and tissues. It works by delivering oxygen at higher percentages than is found in regular air. The normal oxygen level in arterial blood is 80-100 mm Hg; levels below 60 mm Hg can cause physiological effects. Oxygen is administered through various devices like nasal cannulas, masks, tents and venturi masks to precisely deliver the prescribed oxygen concentration. Close monitoring is needed when providing oxygen therapy to ensure safety and prevent drying of tissues or other potential side effects.

1. OXYGEN ADMINISTRATION
Prepared by
Vinil Upendrababu

2. OXYGEN ADMINISTRATION
• Method by which oxygen is supplemented at
higher percentages than what is available in
atmospheric air.
• Oxygen (O2) is administered as a corrective
treatment for conditions resulting in hypoxia
(low level of oxygen in the Cells).

3. • The normal amount of oxygen in the arterial blood
should be in the range of 80 to 100 mm of Hg.
• If it falls below 60 mm of Hg; irreversible physiologic
effects may occur.
• The oxygen administration treats the effects of oxygen
deficiency but it does not correct the underlying causes

4. DEFENITION OF OXYGEN
ADMINISTRATION
• Oxygen administration is the process by which
supplemented oxygen is administered in high
concentration than that of atmospheric air.
• The air that we breathe contain approximately
21% oxygen

5. PURPOSE
• To relieve dyspnea.
• To reduce or prevent hypoxemia (low level of
O2 in blood) and hypoxia (low level of O2 in
cells).

6. Sources of O2
•
Therapeutic oxygen is available from two sources:
1. Wall Outlets(; Central supply)
2. Oxygen cylinders
 Stationary

Portable, mobile or ambulatory.

7. INDICATIONS FOR OXYGEN
ADMINISTRATION.
• Severe respiratory distress (e.g. acute asthma and
pneumonia.)
• Intra and post operatively
• Hypoxia and hypoxemia
• Shock
• Acute myocardial infraction (heart attack)

8. PAO2 AS AN INDICATOR FOR
OXYGEN THERAPY
• PaO2 : 80 – 100 mm Hg : Normal
• 60 – 80 mm Hg : cold, clammy extremities
• < 60 mm Hg : cyanosis
• < 40 mm Hg : mental deficiency, memory loss
• < 30 mm Hg : bradycardia, cardiac arrest
PaO2 < 60 mm Hg is a strong indicator for oxygen therapy

9. GENERAL NURSING RESPONSIBILITIES
• Oxygen must only be administered at the rate and percentage prescribed.
• Explain to the client the dangers of lighting matches or smoking cigarettes, cigars.
Be sure the client has no matches, cigarettes, or smoking materials in the bedside table.
• Make sure that warning signs (OXYGEN - NO SMOKING) are posted on the client’s door
and above the client’s bed.
• Do not use oil on oxygen equipment.( Rationale: Oil can ignite if exposed to oxygen.)
• With all oxygen delivery systems, the oxygen is turned on before the mask is applied to
the client.
• Make sure the tubing is patent at all times and that the equipment is working properly.

10. • Watch for respiratory distress.
• Encourage or assist the client to move about in bed.
• Provide frequent mouth care. Make sure the oxygen contains proper humidification.( Rationale:
Oxygen can be drying to mucous membrane.)
• Discontinue oxygen only after a physician has evaluated the client. Generally, you should not
abruptly discontinue oxygen given in medium-to-high concentrations( above 30%). Gradually
decrease it in stages, and monitor the client’s arterial blood gases or oxygen saturation level. (
Rationale: These steps determine whether the client needs continued support.)
• Always be careful when you give high levels of oxygen to a client with COPD. The elevated levels of
oxygen in the patient’s body can depress their stimulus to breathe.
• Wear gloves any time you might come into contact with the client’s respiratory
secretions.( Rationale: To prevent the spread of infect

11. • Mark oxygen cylinder to indicate whether full or empty.
• Use only carriers with wheel to transport oxygen cylinder,
do not roll the oxygen cylinder.
• Oxygen must only be administered at the rate and
percentage prescribed.
• Do not adjust flow meter until instructed.
• Encourage or assist patient to move about in bed to prevent
circulatory difficulties.

oralsecretion out easily
without anyinterruption in
oxygen delivery.

through nasal cannula
• 1ltr 24%
• 2 28%
• 3 32%
• 4 36%
• 5 40%
• 6 44%

18. MASK
ADVANTAGES
• It delivers high
concentration of
oxygen.
• Its quick and easy to apply
DISADVANTAGES
• It must be removed while talking,
eating, vomiting and drinking.
• It obstruct coughing.
• It blocks vomitus in unconscious
patients.
• Carbon dioxide may build up in the
mask.
• It causes skin irritation.
• Aspiration of vomitus is likely when
mask is in place.

19. • It delivers 35% to 60% oxygen. A flow rate of
6 to 10 L/mnt.

20. NASAL CATHETER :
• The nasal catheter is inserted into the nostrils
reaching up to the uvula & is held by adhesive
tapes
• The catheter does not interfere with the
patients freedom to eat , to talk & to move in
bed
• Flow of 1 to 4 liters of oxygen will be sufficient
to maintain the concentration of 22 to 30 %
oxygen

22. OXYGEN TENT :
• When a patient has a facial injury or for any
other reason cannot tolerate an oxygen mask ,
then this method can be used

23. OXYGEN TENT
Advantages

for patient with controlled
oxygen concentration ,
temperature regulation &
humidity control
• It allows freedom for free
movement in bed
Disadvantages
• Create feeling of isolation

( 10 to 12 liter/ minute )
• There is increased chances of fire
• It requires much time & effort to
clean & maintain a tent

28. THE PARTIAL REBREATHER

at a minimum of 6 L/mnt.

29. The partial re-breathing reservoir
mask:
• The mask has a reservoir bag that must remain inflated
during both inspiration & expiration.
• It collects the first parts of the patients' exhaled air.
• The oxygen flow rate must be maintained at a minimum of
6 L/min to ensure that the patient does not rebreath large
amounts of exhaled air.
• It is used to deliver oxygen concentrations up to 80%

32. THE PARTIAL REBREATHER MASK
Advantages

through openings in mask if
oxygen supply is briefly
interrupted.

of oxygen ( 80%- 100%) at a flow rate 6-15
L/mnt.

35. • Similar to the partial rebreather mask except that
two one way valves are present to conserve the
exhaled air.
• The bag is an oxygen reservoir.

closes and all the exhaled air is vent out and the
patient does not re breath any of the exhaled air.
