تعريف

Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen in a sealed chamber. This concentration is five 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.

أسباب هذا الإجراء

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

  • An air bubble (embolism) which gets into the circulatory system and blocks blood flow
  • Decompression sickness, which can occur when divers or miners come to the surface too quickly
  • Carbon monoxide poisoning
  • Wound healing, especially in patients with poor circulation
  • Radiation therapy injuries following treatment for cancer
  • Skin grafts, flaps, or burns

ما يمكن توقعه

قبل الإجراء

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

وصف الإجراء

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. She may be able to lower the pressure.
  • 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.
