how to increase oxygen level

1. Care of gas exchange and
respiratory function care modalities

2. Non invasive respiratory therapies
• The goal of oxygen therapy is providing
adequate o2 wile decreasing the load of
breathing and reducing stress on heart.

3. Non invasive respiratory therapies
• Indication:
1. Change in respiratory rate or pattern:
hypoxemia or hypoxia.
2. Hypoxemia is decrease in the arterial oxygen
tension in the blood.
3. Hypoxemia leads to hypoxia which is
decrease O2 supply to the tissues.

5. Question to think about
• What are the three methods to
assess oxygen level in the blood?

6. Complication
• It is considered as medication. And it is used with
prescription.
• Oxygen toxicity: when administering more than
50% for more than 48hrs.
• Suppression of ventilation: the stimulus of
respiration is O2 if it is give in high dose it will
suppress the respiratory center as in COPD.
• Other complication: O2 supports combustion so
dangerous for fire so put “oxygen on use” sign.
Change the tubing and its device between
patients to reduce the risk for infection.

7. Methods of oxygen administration
• It is dispensed from cylinder or a pipe in
system (central line).
• Humidifier is use to prevent dryness of
mucous membrane.
1. Nasal cannula is used to provide low to
medium amount of O2.

8. 2. Oropharyngeal is used for short term therapy
for low and moderate concentration of oxygen.
It should be changed every 8hrs.

9. 3. Oxygen mask:
a. Simple mask: gives low to moderate o2. it has
opening for exhalation and draw air when o2
ceases. Adjust it properly to the skin but not to
press tightly to prevent skin break down. (you
can put gauze around the ear).

10. b. Partial re-breather mask: has reservoir bag
which must remain inflated during inspiration
and expiration. High doses of O2 can be
administer as both mask and bag act as
reservoir for o2.

11. c. Non re-breather mask: it has valve to allow air
to go to the mask but not opposite. It allows
exhaled air to exit the mask during exhalaiton.

12. d. Venturi mask: it is accurate for delivering o2.
e. Other oxygen delivery include aerosole
masks, tracheostomy collars and face tent.

13. • face tent

14. Nursing management:
1. Teach patient that it is available in gas, liquid
and concentrated forms.
2. Sign of “o2 in use to be put”
3. If it is in portable device patient can leave the
house or hospital with it.
4. Humidity must be provided.

15. • Compare and contrast between various types
of low and high flow systems page 637.
