UNIT-SEVEN: OXYGEN ADMINISTRATION
Objectives: At the end of the unit the Trainees will be able to:
1. Utilize different oxygenation delivery system when necessary
2. Demonstrate precaution of oxygen administration
3. Deliver oxygen appropriately
Monitor oxygenation level of client
Oxygen is a colorless, odorless, tasteless gas that is essential for the body to function properly
and to survive. When chilled to liquid or frozen to solid it turns a light blue color
Oxygen therapy is the administration of oxygen at a concentration greater than that found in the
environmental atmosphere. The concentration of o2 in room air is 21 %.
Purpose
To provide and maintain a normal supply of O2 for blood and tissues
The goal of oxygen therapy
o Oxygen therapy has three fundamental goals.
o Improve tissue oxygenation
o Decrease work of breathing in dyspneic clients.
o Decrease work of the heart in clients with cardiac disease.
Oxygen transport to the tissue depends on factors such as:
 Cardiac output.
 Arterial oxygen content.
 The adequate concentration of hemoglobin.
 Metabolic requirement.
Oxygen therapy is used to primarily reverse hypoxemia (below normal amount of oxygen
in the blood) which manifested by:
• Change of mental status (progressing through judgment, agitation, disorientation,
confusion, lethargy, and coma).
• Dyspnea
• Increased blood pressure
• Change in heart rate

• Dysrhythmia
• Central cyanosis(late sign)
• Diaphoresis
• Cool extremities
Indications oxygen therapy
 Obstruction in air passage like a foreign body, growth enlarged thyroid.
 Bronchial asthma
 Pneumonia and pulmonary edema.
 Cardiac insufficiency.
 Peripheral circulatory failure.
