First, the foundation

1. What is a medical hyperbaric oxygen chamber?

Hyperbaric Oxygen Chamber (HBOT) is a medical device that helps patients rapidly increase blood oxygen concentration and promote tissue repair by providing a pure oxygen environment higher than normal pressure (1.4-3.0 ATA). It is widely used in the treatment of acute and chronic diseases and postoperative rehabilitation.

2. What is the core principle of hyperbaric oxygen therapy?

Increased physical dissolved oxygen: Under high pressure, the amount of oxygen dissolved in plasma is significantly increased (up to 20 times normal pressure), and oxygen can be supplied to ischemic tissue without relying on hemoglobin.

Promote angiogenesis: Accelerate the reconstruction of damaged blood vessels by upregating growth factors such as VEGF.

2. Indications and contraindications

3. What diseases are commonly treated by hyperbaric oxygen chamber in Top three hospitals?

Emergency: carbon monoxide poisoning, gas embolism, crush injury, necrotizing soft tissue infection.

Chronic diseases: diabetic foot ulcer, radiation osteonecrosis, sudden deafness.

Postoperative recovery: skin grafting/flap surgery, nerve repair after brain injury.

Others: Refer to the American Underwater and High Pressure Medical Society (UHMS) 14 Indications.

4. Which patients are forbidden to use hyperbaric oxygen chamber?

Absolute contraindications: untreated pneumothorax, severe emphysema with bullae, claustrophobia.

Relative contraindications: high fever, uncontrolled seizures, early pregnancy (need to be evaluated by a doctor).

Third, security and risk

5. Is hyperbaric oxygen chamber treatment safe?

Security guarantee:

Comply with the ISO 13485 medical device standard and the national "Medical hyperbaric oxygen chamber safety Technical Specification".

Equipped with multiple safety systems: automatic pressure regulation, dual oxygen supply, emergency pressure relief valve.

Risk warning: In rare cases, air pressure injury of the middle ear may occur (incidence < 1%), which can be prevented by pinching the nose and blowing.

6. How to deal with emergencies (such as power failure)?

Emergency mechanism: the standby oxygen in the cabin can be supplied for 30 minutes, and the pressure relief system can safely relieve the pressure within 5 minutes.

Iv. Treatment process and operation

7. How long does a single treatment take?

Conventional treatment: 90-120 minutes/time (including pressure, pressure regulation, decompression stage), pressure range 1.5-2.5 ATA.

First aid treatment: Adjust according to the condition, such as carbon monoxide poisoning needs 2.8 ATA high pressure treatment for 60 minutes.

8. What should patients do to prepare?

Wear requirements: Change the pure cotton hospital gown, do not bring electronic products, cosmetics and other flammable materials.

Physical status: 1 hour before the treatment to avoid full food, need to complete the ear pressure balance training.

5. Equipment maintenance and support

9. Daily maintenance requirements of medical hyperbaric oxygen chamber?

Daily check: pressure gauge calibration, door tightness test, oxygen concentration monitoring.

Regular maintenance: Comprehensive inspection (including circuit and oxygen supply system) every quarter, and in-depth maintenance by certified engineers every year.

10. Equipment consumables (such as filters) replacement cycle?

Oxygen filter: Replace every 6 months or 500 hours of cumulative use.

Air compressor filter element: replace every 3 months, shorten to 2 months in high frequency use environment.

6. Effect and data support

11. Is there clinical evidence for the effectiveness of hyperbaric oxygen therapy?

Diabetic foot ulcers: Studies show that combined treatment with HBOT improves healing rates by 35% (NEJM, 2021).

Radiation osteonecrosis: 80% of patients experienced significant pain relief and 50% achieved bone tissue regeneration (JAMA Surgery, 2022).

12. When does the treatment effect appear?

Acute disease (e.g., carbon monoxide poisoning) : Recovery of consciousness after 1-3 treatments.

Chronic diseases (such as diabetic foot) : Usually 20-40 treatments are required, with significant improvement seen after 4-8 weeks.

Vii. Cooperation and service support

13. What qualifications do hospitals need to purchase hyperbaric oxygen chambers?

Necessary conditions: medical institution license, hyperbaric oxygen chamber operator qualification certificate (need to pass the National Health Commission certification training).

Optional support: We provide free operation training and 1-year on-site technical guidance.

14. How about the equipment warranty and after-sales service?

Warranty period: 3 years for the whole machine, 10 years for the core components (pressure vessel, control system).

Response time: 24 hours technical support, major failure within 48 hours of the engineer to arrive.
