Introduction
Hyperbaric
Oxygen Therapy (HBOT) is a medical treatment by which oxygen
is administered at greater than normal pressure to a patient
in order to treat specific medical indications.
Mechanism
of action
•
In HBOT, the patient is placed in a specially
designed chamber, the pressure in the chamber is increased,
and 100% oxygen is breathed.
•
Alveolar oxygen pressure is increased,
causing a rise in plasma oxygen content which results in
enhanced tissue oxygen delivery.
Dose
and session duration
•
The amount of pressure increase and the
length of time under pressure are determined by the condition
being treated.
•
Treatment pressures are usually between 2 and
3 times atmospheric.
•
Treatments usually last from 1 to 2 hours at
full pressure.
