Hyperbaric Oxygen Therapy

Definition

Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen in a sealed chamber. This concentration is 5 times higher than the normal air we breathe. The chamber is also pressurized to create 1.5 to 3 times normal atmospheric pressure. These changes can improve blood circulation and the blood’s ability to deliver oxygen to the body.

Reasons for Procedure

This procedure has been used to treat many health problems, including:

Carbon Monoxide Poisoning

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Mild discomfort
  • Nearsightedness—myopia, which can last for weeks or months
  • Sinus damage, ruptured middle ear, or lung damage
  • Damage to the eardrum (tympanic membrane)
  • Oxygen toxicity, which can cause seizures, fluid in the lungs, or respiratory failure
  • Worsening symptoms or increased risk for lung problems in people with heart failure or lung disease

What to Expect

Prior to Procedure

  • Wear comfortable clothes.
  • Bring a book or an activity that you can do in the chamber.

Description of the Procedure

You will lie down on a padded table, which slides into a tube. This is called a single-person chamber. In some cases, the chamber may be large, holding more than a dozen people.

A technician will gradually pressurize the chamber with 100% oxygen. You will be able to talk to this person. While in the chamber, you will be instructed to:

  • Relax and breathe normally.
  • If your ears pop or you have discomfort, tell the technician. The pressure may be lowered.
  • Swallow or blow with your nose pinched to relieve discomfort.
  • After getting to the right pressure, place a clear plastic hood or mask over your head. This will deliver oxygen to you.

If you are at high risk for oxygen toxicity, you may be allowed to breathe regular air for brief periods.

Immediately After Procedure

Over a period of several minutes, the technician will slowly depressurize the chamber. You will likely have some ear popping and feel light-headed and tired. However, you should be able to go back to your daily activities. You may have more than one session over a period of several days.

How Long Will It Take?

½ hour to 2 hours

How Much Will It Hurt?

You will not have any pain. Your ears may feel full.

Average Hospital Stay

Unless you have another medical condition, you will be able to go home after HBOT.

Post-procedure Care

In most cases, there is no special care after treatment.

Call Your Doctor

It is important to monitor your recovery. Alert your doctor to any problems. If any of the following occur, call your doctor:

  • Discomfort or pain in your sinuses or ears
  • Onset of seizures
  • Vision problems
  • Cough, shortness of breath, or chest pain

If you think you have an emergency, call for medical help right away.
