Oxygen is very essential component for living things so as a nurse it is fundamental to assess the level of oxygen in body, and if it is less than necessary action should be taken. Oxygen insufficiency can lead serious illness like lung diseases or breathing difficulties, heart conditions, or certain medical emergencies. When the body doesn't receive enough oxygen, it can lead to symptoms like shortness of breath, dizziness, confusion, rapid heart rate, and in severe cases, it can be life-threatening. Treatment typically involves addressing the underlying cause and, if necessary, providing supplemental oxygen therapy.

3. Introduction of O2 Insufficiency
Oxygen insufficiency refers to a condition where there is an
inadequate supply of oxygen to the body's tissues and organs.
This can occur for various reasons, such as respiratory problems
(like lung diseases or breathing difficulties), heart conditions, high
altitude, anaemia, or certain medical emergencies.
When the body doesn't receive enough oxygen, it can lead to
symptoms like shortness of breath, dizziness, confusion, rapid
heart rate, and in severe cases, it can be life-threatening.
Treatment typically involves addressing the underlying cause and, if
necessary, providing supplemental oxygen therapy.
4. Contd
All life on earth is based on 5 basic elements: Sulfur, nitrogen,
hydrogen, carbon and oxygen.
Amongst these, the element that is most abundant is oxygen.
Oxygen makes up about 65% of the human body.
Odourless, tasteless, and colourless, oxygen is one of the most
important substances without which life would not be able to
exist.
For example, we can go without food for a number of weeks
and survive, we can even go without water for 3-7 days, but we
cannot survive without oxygen beyond 5 minutes.
5. Meaning & Physiology of Oxygenation
Meaning of Oxygenation Oxygenation means the delivery of oxygen
to the body tissue and cells. It is necessary to maintain health.
Physiology of Oxygenation
6. Oxygenation results from the co-operative
function of 3 major systems:-
Respiratory/Pulmonary system
Haematological system
Cardiovascular system
7. Lung Volumes and Capacities
Tidal Volume 500 ml
Inspiratory Reserve Volume
3000 ml
Expiratory Reserve Volume
1000 ml
Residual Volume 1500 ml
Inspiratory Capacity 3500 ml
Functional Residual Capacity
2200 ml
Vital Capacity - 4500 ml
Total Lung Capacity (5700 -
6000 ml)
8. There are three steps in the process of
oxygenation
1) Ventilation,
2) Perfusion
3) Diffusion
Pathway of Air Nasal Cavities (or Oral Cavity) > Pharynx
>Trachea >Primary bronchi (right & left) > Secondary
bronchi > tertiary bronchi > bronchioles > alveoli (site of gas
exchange).
9. Terminology Related to Ventilation & How
its Possible
Pulmonary Ventilation It means movement of air into and out
of lungs. Its main purpose is to supply fresh air.
Ventilation is composed of
- Inspiration - when air flows into the lungs.
- Expiration - when air moves out of lungs.
Adequate ventilation depends upon
- Clear airways
- An intact central nervous system and respiratory center
- An intact thoracic cavity capable of expanding and contracting.
10. Regulation of Respiration
Neural Regulation It maintains rhythm and depth of
respiration and balance between inspiration and expiration.
A) Cerebral cortex
B) Medulla oblongata
Chemical Regulation It maintains appropriate rate and
depth of respirations based on changes in the body's carbon
dioxide, oxygen and hydrogen ion concentration
A) Chemoreceptors
13. Developmental Factor
o Fetus
o Neonates and infants
o Toddler, preschool-aged children and accidents
o Older adults
Behavioural Factors
o Lifestyle
o Medication
14. Environmental Factors The incidence of pulmonary disease is higher in
smoggy, urban areas than in rural areas. In addition, the client's
workplace may increase the risk for pulmonary disease. Occupational
pollutants include asbestos, talcum powder and silica dust, coal dust.
15. Sign and symptom of inadequate
oxygenation
Anxious and tired
Headache, dizziness, irritability and memory loss.
Nausea, vomiting and cyanosis
Oliguria and anuria
Fatigue lethargic
RBC count increases,
Clubbing of fingers
Sometime patient may have pain while breathing
16. Etiological factors
Decreased haemoglobin & oxygen carrying capacity of blood.
Diminished concentration of inspired oxygen which may occur at
high attitude.
Inability of the tissue to extract oxygen forms the blood in case of
cyanide poisoning.
Decreased diffusion of oxygen from the alveoli to the blood as with
in pneumonia.
Poor tissue perfusion with oxygenated blood as with shock.
Impaired ventilation as with multiple rib fracture or chest traumas.
17. Disease / abnormalities Which Cause Oxygen
Insufficiency
Musculoskeletal Abnormalities Rib cage Deformity, Rib &
sternal fracture or trauma of thoracic region. Some times
kyphosis, lordosis or scolliosis and Pectus excavatum etc.
Trauma The person with multiple rib fracture can develop a
flail chest.
Neuromuscular Diseases Disease such as muscular dystrophy
affects oxygenation of tissue by decreasing the clients ability to
expand and contract the chest wall. Ventilation is impaired an
atelectasis, hypercapnia and hypoxemia can occur.
18. CONTD
Central Nervous System Alterations Disease or trauma involving
the medulla oblongata and spinal cord may result in impaired
respiration.
Myocardial Ischemia
Angina pectoris
Myocardial infraction (MI)
Hypoventilation
Hypoxia
Cyanosis
Cerebral Palsy
Syncope
19. Diagnosis & Evaluation of the Patient That Who
Is Having Oxygen Insufficiency
History Collection
focus on the clients ability to meet oxygen needs.
Nursing history for cardiac function includes pain, dyspnoea, fatigue,
peripheral circulation, cardiac risk factors, and presence of past or
current conditions.
Nursing history for respiratory function includes the presence of a
cough, shortness of breath, wheezing, pain environmental exposure,
frequently of respiratory tract infections, past respiratory problem,
current medications use and smoking history or second hand smoke
exposure.
21. MEASUREMENT NORMAL
RANGE
CLINICAL
SIGNIFICANCE
Tidal volume - (TV)
Volume of air inhaled or
exhaled per breath.
5-10 ml/kg Decreased in restrictive lung
disease and older client.
Residual volume (RV)
Volume of air left in
lungs after a maximal
exhalation.
1000 1200 ml
Increase in clients with COPD and
older clients due to decreased
respiratory muscle mass, strength,
elastic recoil and chest wall
compliance.
Functional residual
capacity Volume of air
left in lungs after a
normal exhalation.
2000 2400 ml
Increased in clients, with COPD and
older
Vital capacity (VC)
Volume of air exhaled
after a maximal
inhalation
4500 4800 ml
Decreased in pulmonary edema an
atelectasis and changes associated
with a giving.
Total lung capacity
(TLC) Total volume of
air in lungs following a
maximal inhalation
5000 6000 ml
Decreased in restrictive lung
disease increase in obstructive lung
33. MANAGEMENT OF O2 INSUFFICIENCY
Position Semi fowler/high fowler/prone position also help to
proper ventilation and diffusion in lungs & to raise
oxygenation .
35. CONTD
Oxygen Therapy
Oxygenation by Applying Nasal Cannula
Oxygenation By Applying An Oxygen Mask
Nasal Catheter
Oxygen Tent
Oxygen Therapy In The Home
36. Nursing Diagnosis and Interventions
Impaired gas exchange related to Broncho construction
and inflammation of airways.
Ineffective airway clearance related to increased mucous
production due to upper respiratory infection and
asthma.
Anxiety related to difficulty in breathing as manifested by
asking more doubts.
Fluid volume deficit related to sodium and water
retention as manifested by crackles.
37. CONTD
Infective breathing pattern related to neuromuscular
impairment of respirations (pain, anxiety, decreased
level of consciousness, respiratory muscle, fatigue and
bronchospasm.) as evidenced by altered respiratory
etc.
Imbalanced nutrition less than body requirement
related to poor appetite, shortness of breath,
decreased energy level and increased caloric
requirement as evidenced by weight loss, weakness,
muscle waiting.
38. Nursing Interventions
