Theory

High air pressure decreases the size of gasbubbles in the blood

2 to 3 times that of normal air pressure

High oxygen (100%) intake saturates theblood plasmawith oxygen

Net increase in oxygen delivered to healing

tissues Decreases hypoxia

Increases phagocytic and fibroblastic activity

Biophysical Effects

Blood Flow

Increased oxygen levels causevasoconstriction

Net increase in oxygen delivered to thetissues

Maybe especially beneficial to avascular

structures: Achilles tendon

Rotator cuff

Precautions

Hyperbaric oxygen therapy should only beadministered by trained personnel

Too great of pressure may rupture thetympanic membrane

Increased risk with an inner ear infection

Decongestants may help prevent this

Can increase the output of bodily gasses
