This document defines oxygen and provides normal ranges for various oxygen measurements. It describes how oxygen is supplied in hospitals via pipes or cylinders. Several methods for administering oxygen are outlined, including nasal catheters, nasal cannulas, oxygen masks, oxygen hoods, oxygen tents, Venturi masks, partial rebreather masks, and non-rebreather masks. Flow rates and oxygen concentrations are provided for each method. Risks of long-term high concentration oxygen are also mentioned.

2. Definition
Oxygen is a colourless ,tasteless ,odourless Gas that is
essential for body organ to survive.
PaCo2 - Partial Carbondioxide
Normal Range - 35 to 45 mmhg
Pao2 - Partial OOxyeg
Normal Range in Children - 80 to 100 mmhg
Normal Range in Adult - 50 to 80 mmhg

3. Spo2 full form is -
S – Saturation capillary
P - Peripheral
O2 - Oxygen
Normal Spo2 is - 96 to 100 %

4. Colour of Oxygen Cylinder is -
Black Body and white Neck
Humidifier water change
in every 24 hour.

5. Supply of Oxygen :
Thre are two ways to Supply oxygen in Hospital.
1. By Pipe/ Wall outlet
The pressure Store under 50 to 60 lbs
2. By Oxygen Cylinder
The Pressure under 2200 lbs
( 1000kg/Square inch)

6. Methods of Oxygen
Administartion
There are some methods as is -
1. Nasal Catheter

7. • Flow rate is 2-4 ltr/min.
• Change catheter every 8 to 12 hour.
• Most common method used in HoHospital.
• Inserted to the Uvula.

8. 2. Nasal Cannula / Nasal Pronge

9. • It is Disposable.
• Two Cannula about 1.5 cm.
• Used for Low medium Concentration of Oxygen 24
to 44%
• Flow rate 1 to 6 ltr/min.
• Never Deliver more than 2-3 ltr/min to the patient
with COPD because patient not Tolerate.
• Increase Co2 is called Hypercapnia.
• Decrease Co2 is called Hypocapnia.

10. 3. O2 Mask or Simple mask

11. • Flow Rate is 4 to 8 ltr/min.
• O2 Concentration is 40 to 60%.
• 5 ltr O2 = 40%
• 6 ltr O2 = 45 to 50%
• 8 ltr O2 = 55 to 60 %

12. 4. O2 Hood method

13. • It is a small box, transparent and Dome shape
Device.
• This is used only in infant.
• Flow rate is 2 ltr/min

14. 5. O2 tent Method

15. • It is a Canopy over the patient.
• Canopy should be Transparent.
• Flow rate is 8 to 10 ltr/min.

16. 6. Venturi Mask / Venti Mask

17. • Normal flow rate is 3 to 15 ltr/ltr.
• Best method to Deliver oxygen in COPD patient.
• In COPD Flow rate is < 4 ltr / Min.
• The venturi mask colur Code, flow rate and Oxygen
Concentration -

18. Colour Flow Rate Oxygen
Concentartion
Blue 2 24%
White 4 28%
Orange 6 31%
Yellow 8 35%
Red 10 40%
Green 15 60%

19. 7. Partial Rebreather Mask

20. • Flow rate is 6 to 15 ltr/min.
• Oxygen Concentration 70 to

21. Non Re-breather Mask

22. • Flow Rate is 10 to 15 ltr/min.
• Provide Higher concentartion of oxygen and can be
deliver and oxygen concentration > 90%
• It is most common method to use for oxygen.

23. T- Piece :
• Used on End of E.T tutu.
• Used as weaning from ventilator.
• It Provide Good humidity.
☆ If high Concentration of Oxygen for > 30 day cause
Retrolental Fibroplasia ( Abnormal Fibrous tissue )

24. • N2o * Nitrous Oxide- Laughing Gas
• Use in Analgesic and Anesthesia for O.T
• Colour - Blue Colour.
• Hilium - Colur Brown
• Used in MRI Machine to detect to Image.
