Basic Information about Oxygen Therapy

1. Oxygen Therapy

2. Introduction
Every single cell or tissue needs oxygen to
being survive or performing metabolism.
Oxygen is necessary component for establishing
aerobic metabolism in living organism.

3. Definition
A Process to administer the oxygen to the
patient for treating the Hypoxemia thereby
Hypoxia which may result in tissue injury or
even cell death.

4. Indication
• Respiratory Failure
• Cardiac Failure
• Shock
• Metabolic Disorder
• Anemia
• Cyanide Poisoning
• Intra/Post- Operative Stage

5. Source of Oxygen in Hospital Setting
Oxygen Cylinder Wall Outlets

6. Parts of Oxygen Cylinder
Keys Flow Meter

7. Parts of Wall Outlets
Oxygen Points Flow Meter

8. Methods for Oxygen Administration
• Nasal Prongs/Catheter
• Simple Mask
• Partial Re-breather Mask
• Non Re-breather Mask
• Venturi mask
• Oxygen Hood
• Ambu Bag
• T-Piece
• Endotracheal/Tracheostomy

9. Nasal Prongs/Cannula
Nasal Prongs and Cannula are similar
device to deliver the oxygen. Only difference is
about placement of tip. Nasal Prongs Tip is
placed in Nostril while Nasal Cannula tip is
placed at Oropharynx

10. Nasal Prongs/Catheter
About Device
It is Disposable plastic
silicon material device have
two protruding Prongs for
placement in nostril while
another end is connected with
oxygen source. This is used for
delivering very low amount of
oxygen.
Concentration of oxygen for
delivery
Flow Rate FiO2
1ltr/min 24%
2ltr/min 28%
3ltr/min 32%
4ltr/min 36%
5ltr/min 40%

11. Simple Mask
About Device
It is mask like structure
made up by silicone rubber
able to cover the nose and
mouth of an individual and
secure through as elastic band
behind the head. This may
require high flow of oxygen to
prevent from close ventilation
and deliver around 60% of Fio2
Concentration of oxygen for
delivery
Flow Rate FiO2
5ltr/min 30%
6ltr/min 35%
7ltr/min 40%
8ltr/min 45%
9ltr/min 50%
10ltr/min 55%

12. Mask connected with
reservoir bag and inflated in both
condition inspiration and expiration.
Between the Mask and bag
there is no valve or obstruction
through which expired air mixes with
oxygen and make close ventilation.
This is helpful for COPD
Patient at the time when they need
high concentration of oxygen but
CO2 also important element of
respiration
Flow Rate FiO2
10ltr/min 60%
11ltr/min 65%
12ltr/min 70%
13ltr/min 75%
14ltr/min 80%
15ltr/min 90%

13. Non Re-Breather Mask
About Device
Device is similar to the
Partial Re-Breather mask the
only difference that between
the mask and bag Valve is
found that obstruct the exhale
air to mixing with oxygen.
It is useful for
delivering higher oxygen
concentration at lower flow
rate,
Concentration of oxygen for
delivery
Flow Rate FiO2
10ltr/min 95%

14. Venturi Mask
About Device
Device is constructed
for mixing a accurate amount
of air with the oxygen so that
constant oxygen concentration
may deliver to the patient.
Mask for delivering the
oxygen is similar to simple
mask it just connected with
specially designed connector
between mask and oxygen
source
Concentration of oxygen for
delivery
Flow Rate Color FiO2
 2-4ltr/Min. Blue 24%
 4-6ltr/Min. White 28%
 6-8ltr/Min. Orange 32%
 8-10ltr/Min. Yellow 36%
 10-12ltr/Min. Red 40%
 12-15ltr/Min. Green 60%
