3. Respiratory system
The respiratory system provides oxygen to the tissues and organs of the body
An average adult at rest will breathe approximately 10 – 20 times each minute

4. Respiratory system The Upper Airway Mouth Nose Larynx – Voice box
Trachea - Windpipe

5. Respiratory system
The Lower Airway
Bronchi
Lungs
Alveoli

6. Circulatory system
Red blood cells or haemoglobin cells carry Oxygen

7. Nervous system input Carbon dioxide levels rise
Impulse to breath in Oxygen
Exhale Carbon dioxide

8. Muscles used in respiration
The diaphragm
Internal intercostal muscles
External intercostal muscles

9. Inspiration and Exhalation
The diaphragm and the intercostal muscles contract increasing space in the chest and creating negative pressure which draws air in
Muscles then relax decreasing the space in the chest creating pressure thus forcing air out

10. Composition of air Inspired air Nitrogen (N) 79% Oxygen (O2) 20%
Carbon dioxide (CO2) 1%
Inert gases
Expired air
Nitrogen (N) 79%
Oxygen (O2) 16%
Carbon dioxide (CO2) 4%
Inert gases
Can change depending on air quality
From the oxygen we breathe in we use approximately 25%
The rest is dispelled with when we breathe out, along with other gases including carbon dioxide

11. When to give Oxygen High flow 15 LPM 100% CPR Major head injury Shock
Sepsis
Anaphylaxis
Near drowning
Carbon monoxide poisoning
Pulmonary haemorrhage

12. When to give Oxygen Medium flow 5-10 LPM 40% Acute asthma
Shortness of breath
Lung disease
Acute heart failure
Acute anaemia
Sickle cell anaemia

13. When to give Oxygen Low flow 4 LPM 28% COPD Exacerbation of CF
Chronic neuromuscular disorder
Chest wall disorders
Morbid obesity

14. Oxygen saturation SPO2 Pulse oximetry Normal > 94% Low < 94%
COPD normal 88-94%

15. When to give Oxygen
If in any doubt give oxygen until EMS help arrives, or patients conditions improve significantly

16. When to give Oxygen Oxygen contradictions Paraquat poisoning
Neonate unless cyanosed

17. Equipment Oxygen cylinder Carry bag Mask including tubing
Face/bag mask

18. Equipment

19. Storage Always store and move Oxygen with industry approved equipment
If being carried in a vehicle do not forget a compressed gas sign 19

20. Record keeping
Remember if Oxygen has been given a record must be kept:
Name of patient
Time given
Concentration given i.e. 100%
Effects on condition i.e. change SPO2 / mental state/colour 20

21. Lack of Oxygen Hypoxia Lack of Oxygen in body tissue Hypoxaemia
Lack of Oxygen in the blood 21
