Definition • Oxygen therapy is defined as the administration
of oxygen by inhalation from a cylinder , piped in system liquid oxygen reservoir or oxygen concentration by various methods to relieve anoxemia (reduction in oxygen content of blood )
![Page 3: Oxygen administration](https://reader035.vdocuments.us/reader035/viewer/2022062900/58ce9ac01a28ab8c3b8b7443/html5/thumbnails/3.jpg)
Purposes • To facilitate normal metabolism of the tissues
• To reduce / correct arterial hypoxaemia ( low concentration of oxygen in the blood ) & tissue hypoxia
![Page 4: Oxygen administration](https://reader035.vdocuments.us/reader035/viewer/2022062900/58ce9ac01a28ab8c3b8b7443/html5/thumbnails/4.jpg)
Indications • Breathlessness or labored breathing
• High altitudes
• Shock & circulatory failure • Patient under anesthesia
• Patients who are critically ill
• Patients with a decreased respiratory capacity

contraindications• Administer with caution to the patient with COPD(emphysema + chronic bronchitis + asthma) as it includes hypoventilation
• Atelectasis (collapse of lung) • Oxygen toxicity

Methods of oxygen delivery 1. Nasal catheter :
• The nasal catheter is inserted into the nostrils reaching up to the uvula & is held by adhesive tapes
• The catheter does not interfere with the patients freedom to eat , to talk & to move in bed
• Flow of 1 to 4 liters of oxygen will be sufficient to maintain the concentration of 22 to 30 % oxygen

2. Nasal cannula : • A nasal cannula is a simple comfortable
device , the two cannula about 1.5 cm (half inch ) long , protrude from the centre of a disposable tube & are inserted into the nose
• Low flow, Up to 5 liter of oxygen can provide through nasal cannula

3. Oxygen by mask : • Oxygen mask covers the patient’s nose &
mouth • Mask is advantageous for those patients
who are unable to breathe through the nose
• Flow of 8 to 12 liters of oxygen will maintain the concentration of 25 to 60 % of oxygen

4. Oxygen tent :
• When a patient has a facial injury or for any other reason cannot tolerate an oxygen mask , then this method can be used
• Certain advantages & disadvantages for using a oxygen tent
• It provides an environment for patient with controlled oxygen concentration , temperature regulation & humidity control
• It allows freedom for free movement in bed
• Create feeling of isolation
• It requires high volume of oxygen ( 10 to 12 liter/ minute )
• There is increased chances of fire
• It requires much time & effort to clean & maintain a tent

Care of oxygen cylinder• Always use cylinder of metal case to prevent
danger of falling & breaking
• Oxygen cylinder should be placed at head end of the bed
• Any source of fire should be kept away from cylinder for fear of fire
• Oxygen cylinder should be placed at cool temperature
![Page 15: Oxygen administration](https://reader035.vdocuments.us/reader035/viewer/2022062900/58ce9ac01a28ab8c3b8b7443/html5/thumbnails/15.jpg)
• When cylinder are empty , always marks i.e. “ empty “ & send for filling
• Inspect the apparatus at frequent intervals & make sure for its good working condition
• To test any leakage in the regulator soap leather may be used

Nurse’s responsibility for administration of oxygen • Check the name & bed no. & other identification
of patient
• Check the diagnosis & need for oxygen therapy
• Check the doctors order for the initiation of the therapy , the dosage etc
• Check the doctors order for specific precaution regarding the movement of the positioning of the patient
![Page 18: Oxygen administration](https://reader035.vdocuments.us/reader035/viewer/2022062900/58ce9ac01a28ab8c3b8b7443/html5/thumbnails/18.jpg)
• Assess the patient for any sign of clinical analysis ex: cyanosis
• Check the patients vital sign • Check the result of arterial blood gas analysis
• Note any signs of pulmonary dysfunction

![Page 26: Oxygen administration](https://reader035.vdocuments.us/reader035/viewer/2022062900/58ce9ac01a28ab8c3b8b7443/html5/thumbnails/26.jpg)
After care of the patient & article • Stay with patient
• Keep the patient warm & comfortable
• Evaluate the patients progress by observing the vital signs
• Watch the patient for any deteriorating symptoms after the removal of oxygen inhalation
