When Is A Hyperbaric Chamber Used

When the patient’s tissue cells are in urgent need of high concentrations of oxygen at the cellular level, and conventional blood circulation or breathing oxygen supply can no longer meet the repair needs, hyperbaric oxygen therapy (HBOT) should be on the stage. The most typical examples include chronic wounds (such as diabetic foot ulcers), decompression sickness (commonly known as diving disease), carbon monoxide poisoning, and tissue damage after radiation therapy.

How Does Hyperbaric Oxygen Therapy Work?

In a normal environment, the oxygen we inhale is mainly transported by hemoglobin in red blood cells, which is like transporting goods by bus, with limited parking spaces and an upper limit on transport capacity. But in the special environment of hyperbaric oxygen chamber, the situation has changed. We will provide 100 percent pure oxygen to the patient and raise the cabin pressure to 2 to 3 times normal atmospheric pressure (ATA). According to the law of gas dissolution in physics, oxygen no longer depends only on red blood cells, but can be directly and physically dissolved in plasma, cerebrospinal fluid and body fluids. This high concentration of dissolved oxygen can be used as “osmosis”, bypassing damaged or blocked blood vessels and perfusing directly into tissues that are on the edge of hypoxia. This physical pressure effect is often beyond the reach of ordinary oxygen inhalation equipment.

Core Clinical Indications

In the medical profession, we usually use hyperbaric oxygen chambers to deal with the following types of complex situations when traditional treatments are inadequate:

Management of chronic wounds (especially diabetic foot)

For patients suffering from diabetic foot ulcers for a long time, wound healing is extremely slow, and even tissue necrosis occurs. This is because the local microcirculation is too poor. In this case, HBOT is like the catalyst, which can significantly promote angiogenesis and collagen synthesis. Frankly, without the oxygen supply in this high-pressure environment, many patients’ wounds may never heal on their own.

Sudden Emergency

In some life-threatening emergency situations, the hyperbaric oxygen chamber is the last “killer”:

• Carbon monoxide poisoning: hyperbaric oxygen can forcibly “squeeze” the carboxyhemoglobin bound to hemoglobin, quickly restore blood oxygen transport capacity, and prevent irreversible nerve damage.
• The Bends: High pressure can reduce the volume of nitrogen bubbles in the blood, which is a physical means of saving lives.

Radiation-induced tissue damage (radiation necrosis)

Many cancer patients after receiving radiation, although the tumor disappeared, but the healthy soft tissue or bone may appear delayed damage. This radiation necrosis is tricky, but hyperbaric oxygen can improve local blood supply, reduce inflammation, and prevent further deterioration of the damaged area.

Advanced Applications For Specific Medical Needs

In addition to the common indications mentioned above, we also use oxygen chambers when dealing with some stubborn diseases:

• Gas gangrene and osteomyelitis: A hyperbaric oxygen environment is fatal to anaerobic bacteria. For refractory osteomyelitis, it can assist antibiotics to play a better bactericidal effect.
• Sudden deafness: Many doctors may not notice that if the oxygen supply to the inner ear can be increased as soon as possible, HBOT actually has a very good performance in saving the patient’s hearing.
• Severe burns: For large-area burns, this therapy can effectively reduce edema and improve the survival rate of skin grafting. After all, oxygen is the foundation for tissue survival.

When Should You Consider Hyperbaric Oxygen Therapy?

As a responsible doctor, I usually advise patients to consider entering the cabin at the following two key points:

First, when the conventional treatment plan has “hit the wall.” For example, dressing changes, antibiotics or routine vascular surgery have been done, but the wound still shows no signs of improvement, when hyperbaric oxygen can often break the ice.

Second, when an organ or limb needs to be saved urgently. In the face of the risk of tissue decay caused by hypoxia, hyperbaric oxygen intervention must be carried out immediately in order to preserve the function of hands and feet or organs.

Hyperbaric oxygen therapy is like a bridge between modern conventional medicine and the body’s self-healing instinct. Of course, the specific treatment plan must be decided by the multidisciplinary medical team. If you or a family member is experiencing hypoxia-related problems, I strongly recommend that you consult with a professional to see if HBOT is appropriate to add to your treatment list.
