The importance of Oxygen
Oxygen is essential for life in that it combines chemically with Glucose to provide energy for the metabolic processes of the body, upon which we all depend to survive.
Oxygen therapy should never be withheld from any patient suffering from hypoxia (see below) except for instances of Paraquat poisoning where the oxygen increases the toxicity of the poison.
Every cell of the body must have a continuous supply of oxygen, but in cases of trauma or illness some organs of the body or the body as a whole, may receive an inadequate amount. This lack of oxygen is termed hypoxia.
By increasing the oxygen levels in the lungs via oxygen therapy when can reverse the effects of hypoxia on the brain heart and other vital organs.
Oxygen is an odourless, colourless gas that makes up one fifth of the earths atmosphere
We breathe in 21% oxygen
We breathe out 16% oxygen
So the body needs only 5% oxygen to survive
Conditions that benefit from oxygen therapy include:
Cardiac/respiratory arrest Spinal and pelvic injuries Difficulty
in breathing Drowning/unconsciousness Cardiac conditions/shock Toxic
Fitting/convulsions/fainting COAD (Chronic Obstructive Airway Disease)
COPD (Chronic Obstructive Pulmonary Disease) Chest and head injuries
Emphysema Burns Chronic Bronchitis
