Treatment with pure oxygen inside a pressurized chamber


Hyperbaric Oxygen Therapy (HBO) involves breathing pure oxygen under increased atmospheric pressure to promote the body’s natural healing ability and treat various conditions. The treatment increases your oxygen intake by 10-20 times the normal amount and enhances blood circulation.


HBO can speed up the healing of chronic wounds and skin injuries from bruising and swelling to burns, treat sudden hearing loss, and relieve office syndrome and insomnia.


“HBO increases oxygen intake by 10-20 times
revitalizing the body holistically.”



  • HBO helps stimulate cell functions, repair tissue injury and can increase the generation of blood stem cell by up to 8 times, accelerating wound closure.
  • The treatment also helps minimize infection by improving white blood cells’ disease-fighting efficiency and inhibiting the growth of disease-causing pathogens such as bacteria and fungi.
  • HBO can reverse oxygen deprivation caused by blood loss, shock, or severe smoke inhalation.



  • Suitable for treating diving-related injuries including decompression sickness, aka the bends.
  • Suitable for patients with chronic or slow-healing wounds, trauma-related bruising and swelling or burns.
  • Suitable for patients with chronic bone infection.
  • Suitable for patients with sudden hearing loss.

Hyperbaric Oxygen Therapy (HBO) uses pure oxygen at a high atmospheric pressure to increase oxygen intake to 10-20 times the normal amount, boosting oxygen supply to the body and improving circulation.


HBO works by increasing the supply of oxygen and promoting the circulation of blood to the capillaries. This is beneficial for a variety of conditions, from heavy swelling and bruising from contact injury to surgery wounds, infected wounds, infection leading to cell necrosis, burns and scalds, as well as for soft tissue reconstruction.


More than half of the patients who seek HBO treatment at Thonburi Hospital come to us with sudden sensorineural hearing loss – sudden deafness from auditory nerve vascular compression. HBO helps deliver more oxygen to the auditory vein, increasing the chance that the patient will regain better hearing. Also used to treat many other conditions including stroke, cerebral palsy, sports-related injuries and anemia, HBO offers an alternative for those suffering from office syndrome or insomnia and provides anti-aging benefits as well.


HBO treatment at Thonburi Hospital uses 2.4 kPa pressure, corresponding to diving at the depth of 45 feet (14-15 meters). Treatment length varies according to the patient’s condition. Sessions start from 1.30 hours, and a variety of treatment courses are available ranging from 5, 10 to 30 sessions (ideal for slow-healing wounds).
โดยบรรยากาศในการรักษาเปรียบได้เหมือนกับการขึ้นเครื่องบินหรือการดำน้ำแห้ง สิ่งสำคัญคือคนไข้ที่ทำการรักษาจำเป็นต้องได้รับคำแนะนำที่ถูกต้องจากแพทย์และพยาบาล เปลี่ยนชุดพร้อมรับการบำบัดด้วยผ้าฝ้าย งดอุปกรณ์ที่เป็นตัวนำไฟฟ้าก่อนเข้าใช้งาน โดยระหว่างการใช้สามารถดูทีวี และขยับพลิกตัวได้เพื่อความสบาย
Undergoing HBO treatment feels similar to being on an airplane or dry diving. Before treatment begins, it is important that the patient receive advice about the procedure from the medical team. The patient then changes into a cotton clothing and leaves all electrical and electronic appliances outside the hyperbaric chamber. During treatment you can watch TV and change positions to feel more comfortable.


Some precautions need to be taken. If you suffer from respiratory, sinus or ear infection, or a lung disease or lung injury where air gets trapped in tissue outside air sacs in the lungs, you need to undergo a checkup before receiving hyperbaric oxygen therapy.
