ANDI Oxygen Administration



Oxygen therapy is the administration of oxygen as a medical intervention, which can be for a variety of purposes

in both chronic and acute patient care. Oxygen is essential for cell metabolism, and in turn, tissue oxygenation

is essential for all normal physiological functions. The ANDI Oxygen Administration course teaches the

procedures of oxygen administration for diving emergencies.


Room air only contains 21% oxygen, and increasing the fraction of oxygen in the breathing gas increases

the amount of oxygen in the blood. When 100% oxygen is needed, it may be delivered via a tight-fitting

face mask. Oxygen can be administered in other ways, including specific treatments at raised air

pressure, such as hyperbaric oxygen therapy.


High blood and tissue levels of oxygen can be helpful or damaging, depending on circumstances and

oxygen therapy should be used to benefit the patient by increasing the supply of oxygen to the lungs and

thereby increasing the availability of oxygen to the body tissues, especially when the patient is suffering

from hypoxia and/or hypoxaemia.
