description
Description
  • Exposes the patient (or an extremity) to a:
    • High breathable oxygen environment
    • High air pressure
  • Saturates blood with oxygen
used for
Used For
  • Wound healing
  • Soft tissue healing*
    • Sprains
    • Strains
    • Contusions
    • Inflammation
    • Delayed onset muscle soreness
  • Following cerebral strokes
  • Treatment of the Bends

* Efficacy as not been substantiated

theory
Theory
  • High air pressure decreases the size of gas bubbles in the blood
    • 2 to 3 times that of normal air pressure
  • High oxygen (100%) intake saturates the blood plasma with oxygen
    • Net increase in oxygen delivered to healing tissues
      • Decreases hypoxia
      • Increases phagocytic and fibroblastic activity
biophysical effects
Biophysical Effects

Blood Flow

  • Increased oxygen levels cause vasoconstriction
  • Net increase in oxygen delivered to the tissues
  • Maybe especially beneficial to avascular structures:
    • Achilles’ tendon
    • Rotator cuff
biophysical effects6
Biophysical Effects

Wound Healing

  • Improved by:
    • Oxygen accelerating phagocytosis
    • Decreasing hypoxia
    • Antimicrobial effect
    • Increased ATP levels
biophysical effects7
Biophysical Effects

Tissue Regeneration

  • Improved wound healing assists tissue regeneration
  • Increased rate of fibroblast proliferation
  • Also used for:
    • Fracture healing
    • Reducing delayed onset muscle soreness
    • Lacking clinical evidence
precautions
Precautions
  • Hyperbaric oxygen therapy should only be administered by trained personnel
  • Too great of pressure may rupture the tympanic membrane
    • Increased risk with an inner ear infection
    • Decongestants may help prevent this
  • Can increase the output of bodily gasses
contraindications
Contraindications
  • Pregnancy
  • Inner ear infection
  • Tympanic membrane rupture
  • Upper respiratory infection
  • Sinus conditions
  • Lung disease
  • Asthma
  • Seizure disorders
  • Optic neuritis
  • Pneumothorax
  • Claustrophobia
instrumentation
Instrumentation

Chamber

  • May hold one or more people

Oxygen Administration

  • Treatments administered at 95 to 100% O2
  • Oxygen delivered via an air mask

Pressure

  • Adjusts the chamber temperature from 1 to 3 atmospheres
instrumentation11
Instrumentation

Topical Administration

  • Wounds:
    • Patch is applied over the area
  • Extremity
    • Appliance is placed over the extremity
  • 100% oxygen is used to inflate the device
  • In some cases the patient will breath 95 to 100% oxygen
treatment duration
Treatment Duration
  • Using 100% oxygen and 2.5 atmospheres:
    • 90 to 100 minutes

Or

    • 3 30-minute session
    • The patient is exposed to normal air and air pressures between sessions
maintenance
Maintenance

After Each Use:

  • Clean the interior of the chamber
  • Clean or replace the oxygen mask

As Indicated:

  • A qualified technician should:
    • Calibrate the pressure gauge
    • Inspect and repair the unit
