The document discusses various methods of oxygen administration. It defines oxygen administration as providing oxygen at a higher concentration than atmospheric air. Various sources of oxygen are described including wall outlets and cylinders. Signs of hypoxemia that indicate the need for oxygen therapy are provided. Common indications for oxygen therapy include cyanosis, dyspnea, and hypoxemia. Different devices for oxygen delivery are outlined like nasal cannulas, masks, hoods, and tracheostomy collars along with their advantages and disadvantages.

1. OXYGEN ADMINISTRATION

2. DEFINITION
Oxygen administration is the process
by which supplemented oxygen is
administered in high concentration
than that of atmospheric air.

3. OXYGEN SOURCES
•Wall outlets (Central
supply).
The oxygen is supplied
from a central source
through a pipeline.

4. OXYGEN CYLINDER

5. 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

6. INDICATIONS
• Cyanosis
• Dyspnoea
• Hypoxemia
• Hypoxia
• Respiratory distress
• Shock
• Anaemia
• Acute myocardial infraction
• During anaesthesia for surgery

8. OXYGEN DELIVERY

9. •These contribute partially to the inspired gas the
patient breathes
•These provide total amount of inspired air. A specific
percentage of oxygen is delivered independent of the
patients breathing

SUGGESTED
FLOW RATE

NG
1 L/mnt 24
2 L/mnt 28
3 L/mnt 32
4 L/mnt 36
5 L/mnt 40
6 L/mnt 44

11. ADVANTAGES DISADVANTAGES
Client able to talk and eat
with oxygen in place
Easily used in home settings
Safe and simple
Easily tolerated
Delivers low concentrations
Unable to use with nasal
obstruction
Drying to mucous membranes so
flow greater than 6L/mnt needs
to be humidified
Can dislodge from nares easily
Causes skin irritation or
breakdown over ears or at nares
Not good for mouth breathers
Patients breathing pattern affects
exact Fio2

12. SIMPLE OXYGEN FACE
MASK
It delivers 35% to 60%
oxygen.
A flow rate of
6 to 10 L/mnt.

13. ADVANTAGES DISADVANTAGES
 Simple to use
 Inexpensive
 Can provide
increased
delivery of
oxygen for short
period of time.
 Difficult to keep
mask in position
over nose and
mouth
 Potential for skin
breakdown
 Uncomfortable
for patient while
eating or talking

14. THE PARTIAL REBREATHER
MASK
It is used to deliver oxygen
concentration up to 80%.
The oxygen flow rate must be
maintained
at a minimum of 6 L/mnt

15. ADVANTAGES
•Client can inhale room air through openings in mask if
oxygen supply is briefly interrupted
•Delivers moderate oxygen concentration
DISADVANTAGES
•Requires tight seal ( eating and talk difficult,
uncomfortable)

16. THE NON RE -BREATHER
MASK
This mask provides the
highest
concentration
of oxygen ( 80%- 100%)
at a flow rate 6-15 L/mnt.

17. ADVANTAGES
• Delivers the highest possible oxygen concentration
• Suitable for patient breathing spontaneous with severe
hypoxemia
DISADVANTAGE
• Impractical for the long term therapy
• Malfunction can cause co2 build-up
• Suffocation
• Expensive
• Uncomfortable

18. HIGH FLOW DELIVERY SYSTEM
VENTURI MASK
It is a high flow oxygen delivery
delivery device. Oxygen from
40-50% At litters flow of 4 to 15
L/ mint. The mask is constructed
so that there is a constant flow of
room air blended with a fixed
concentration of oxygen.

19. COLOR FiO2 O2 Flow
Blue 24% 2 L/mnt
White 28% 4 L/mnt
Orange 31% 6 L/mnt
Yellow 35% 8 L/mnt
Red 40% 10 L/mnt
green 60% 15 L/mnt

20. ADVANTAGES DISADVANTAGES
Delivers most precise
oxygen concentration
Doesn’t dry mucous
membranes
• Uncomfortable
• Risk for skin irritation
• Produce respiratory
depression in COPD
patient with high
concentration of oxygen
50%

21. TRACHEOSTOMY COLLAR
Direct to the trachea. To
deliver oxygen, humidity, and
medication to patients with
tracheostomies. The oxygen
flow rate is 8- 10 L/mnt. It is
comfortable and more
efficient.

22. ADVANTAGES
•deliver high concentration of oxygen
•maintain saturation level
•stable and not moved
•good humidity
DISADVANTAGES
•Heavy with tubing
•Regular cleaning
•Chance for infection

23. T- PIECE
T- Piece adaptor is used on end
of endotracheal tube to provide
humidification and oxygen
therapy. The oxygen flow rate is
8 – 10 L/mnt . And 30% - 100%
oxygen can be given

24. OXYGEN HOOD
It covers only the head
allowing access to the lower
body. Ideal for short term use
for neonates and infants. O2
and air premixed passed
through heated humidifiers.
Oxygen flow rate is 8-10 L/mnt

25. TRANSTRACHEAL THERAPY
Trans tracheal catheter is used to
deliver oxygen directly into the
lungs. A small plastic catheter is
surgically placed in your neck
and sits in the windpipe. Here the
flow rate is 1-4 L/mnt. And the
oxygen 60% - 100%

26. ADVANTAGES DISADVANTAGES
• Lower O2 use
• Eliminates nasal and skin
irritation
• Increased exercise tolerance
