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.
