HBOT - At a glance.



Oxygen is a colorless, odorless gas that makes up about 21% of the atmosphere. It is essential for life for two main reasons:

1. Oxygen is one of the body’s basic building blocks. All of the body’s major components – water, protein, carbohydrate, and fat – contain oxygen.

2. Oxygen helps promote certain chemical reactions within the body that result in energy production. Energy is needed for proper circulation, respiration, digestion, temperature control, and many other important functions.

Nature has proven that healing cannot take place without appropriate oxygen levels in the body’s tissues. Many serious health problems stem from or are complicated by tissues having low oxygen levels. In many cases adequate oxygen cannot reach the damaged areas. Without adequate oxygen in the tissues, the body’s natural healing process fails to function properly, and we begin to see damaged tissues, decreased tissue function, slow healing, dry & sagging skin, aging,  fatigue, wrinkles,  and a variety of other symptoms.

Oxygen given under normal atmospheric pressure is not enough to raise tissue oxygen levels to reverse this lack of oxygen because red blood cells cannot carry and release enough extra oxygen. In order to overcome the oxygen starvation and raise tissue oxygen levels high enough for optimal healing to occur, the oxygen must be delivered under slightly increased atmospheric pressure.

Blood is made up of three main components: White blood cells that help fight infection; red blood cells that carry oxygen; and plasma, which is the fluid that carries both kinds of cells throughout the body.

Normally, only the red blood cells deliver oxygen, via a protein called hemoglobin, to the body’s tissues and cells. A healthy person’s hemoglobin is 97% saturated with oxygen when exposed in our lungs to normal air, or 100% saturated when breathing pure oxygen. Whether breathing air or pure oxygen, the limited number of red blood cells can only deliver a certain level of oxygen to the body’s tissues.

Hyperbaric Oxygen Therapy (HBOT) is a 300 year old medical treatment that consists of administering 100% oxygen at greater than atmospheric (sea level) pressure in order to improve and correct certain medical conditions. The underlying principle of hyperbaric oxygen therapy is quite simple: HBOT saturates the body and its tissues with oxygen so they can function properly.

When HBOT is used, you are breathing 10 times the regular amount of oxygen under increased pressure. These increased oxygen molecules are not only dissolved in the red blood cells, but also forced into the blood plasma, which makes up the bulk of the blood. This allows oxygen to be delivered to every parts of tissues and cells that  that may be deprived of oxygen. 

Oxygen is transported by blood in two ways: Chemically, bound to haemoglobin, and physically, dissolved in plasma. The main effect of HBO is hyperoxia. During this therapy, oxygen is dissolved physically in the blood plasma.

HBOT forces oxygen into the body under pressure, oxygen dissolves into all of the body’s fluids including the blood plasma, the lymph, and the cerebrospinal fluid surrounding the brain and spinal cord. All of these fluids carry the extra oxygen to the tissues and cells of the body, even where circulation is poor or blocked. In short, Hyperbaric Oxygen Therapy (HBOT) works by saturating a person’s blood and plasma with oxygen resulting in increased oxygen delivery to tissues.

The physiological effects of Hyperbaric Oxygen Therapy includes:  vasoconstriction and enhanced oxygen delivery, reduction of edema, phagocytosis activation and also an anti-inflammatory effect - enhanced leukocyte function,  neovascularization - angiogenesis in hypoxic soft tissues, osteoneogenesis as well as stimulation of collagen production by fibroblasts are known long-term effects. Hyperbaric Oxygen Therapy HBOT Chamber india, HBOT Chamber india, HBOT India, India HBOT chamber, india hyperbaric oxygen therapy chamber, india hyperbaric oxygen therapy indications, india hyperbaric oxygen therapy information, Hyperbaric Oxygen Therapy HBOT Chamber india, HBOT Chamber india, HBOT India, India HBOT chamber, india hyperbaric oxygen therapy chamber, india hyperbaric oxygen therapy indications, india hyperbaric oxygen therapy information,

HBOT - Contraindications & Precautions


Absolute contraindications:

Include untreated pneumothorax and use of bleomycin, disulfiram, doxorubicin and mafenide acetate. Contraindicated drugs must be discontinued before Hyperbaric Oxygen Therapy.

List of a few known contraindication: 1) History of spontaneous pneumothorax. 2) Severe sinus infection. 3) Upper respiratory infection. 4) Asymptomatic pulmonary lesions on chest x-ray. 5) Uncontrollable high fever (greater than 39C). 6) History of chest or ear surgery 7) Congenital spherocytosis. 8) Any anemia or blood disorder (Although HBOT treats different types of anemia. 9) Any convulsive disorder though many patients have seizure disorder and are treated successfully with HBOT. 10) History of optic neuritis or sudden blindness. 11) Middle ear infection. 12) Diabetes mellitus (insulin therapy). Many diabetic wound patients are diabetic and are treated successfully with HBOT. 13) Pregnancy. 14) Nicotine use/addiction. 15) Acute Hypoglycemia (Many patients are treated successfully with HBOT.) 16) Emphysema with CO2 retention.

Relative contraindications 

Should be observed with caution or consideration, but do not prohibit. They include seizure disorders, emphysema with carbon dioxide retention, high fever, history of spontaneous pneumothorax, optic neuritis, upper respiratory infection, pregnancy, congenital spherocytosis, implanted pace makers and epidural pain pumps. Cancer Chemotherapy agent doxorubicin (Adriamycin) is thought to become cardio toxic when used concurrently with Hyperbaric Oxygen Therapy. Treating patients with Hyperbaric Oxygen Therapy after doxorubicin is stopped for 2-3 days.

Complications & Precautions:

Barotrauma: 

Virtually no patients should have barotraumas if each dive should be observed manually, and at the first sign the pressure is adjusted or reversed to relieve any discomfort.

Confinement Anxiety: 

Oxygen is natural an anti-anxiety agent for patients. A thoruough counseling should remove this condition. Most of the patients get rid of this after the first treatment.

Oxygen Toxicity: 

Pulmonary and CNS – 1 in 10,000 people may experience this but no permanent effects result from this occurrence. There are 14 signs that patients display before experiencing oxygen toxicity that the CHT is trained to recognize. It is recommended that the chambers are operated manually, if a patient should start to display symptoms, the pressure is reversed and symptoms are resolved. Oxygen Toxicity occurs in less than 1 in 10,000 treatments. Does not occur if treated with in recommended pressures and limitation in number of treatments.

Myopia:

Minor eyesight changes due to temporary curvature in the lens while undergoing slight pressurization. Gradually reverses after cessation of HBOT when the lens flattens out again.

Precautions to be followed while entering the Hyperbaric Oxygen Therapy Chamber:

Because the chamber is pressurized with 100% oxygen, certain items can not be taken inside. These include lighters or matches, cigarettes, nylons, wigs, or hair pieces, petroleum jelly, ointments, hearing aids, watches, makeup, lipstick or lip balm, hair spray, hair oil or relaxers, synthetic clothing or hard contact lenses and as advised by your hyperbaric center safety regulations.

HBOT - How it effects the blood flow ?

Normal Blood Flow:

There is 21% oxygen in the air that we breathe, and our lungs transfer this oxygen to our red blood cells (via hemoglobin). These oxygen-filled red blood cells are carried around the body by the plasma (fluid), which travels through the blood vessels. The oxygen diffuses into the surrounding tissue ensuring that it is delivered to where it is needed most.



Normal Blood Flow


Restricted Blood Flow:

When there is a restriction (occlusion) in blood flow due to surgery, illness, or injury, the red blood cells block the blood vessel and are unable to transfer oxygen to the cells on the other side of the occlusion. This causes swelling and starves the area of oxygen, causing hypoxia (a lack of oxygen); when this occurs the tissue begins to break down.


Restricted Blood Flow


Hyperbaric Oxygenation:

Breathing 100% oxygen under pressure causes the oxygen to diffuse into the blood plasma. This oxygen-rich plasma is able to travel past the restriction, diffusing up to 3 times further into the tissue. The pressurized environment helps to reduce swelling and discomfort, while providing the body with at least 10-15 times its normal supply of oxygen to help repair tissue damaged by the original occlusion or subsequent hypoxic condition. Hyperbaric Oxygenation (HBOT) directly increases the saturative effects of tissue oxygenation slowing and reversing hypoxic induced apoptosis – restoring blood supply to the compromised region by the development of new capillary networks (angiogenesis) enabling the body to alter the course and impact of the disease process.


Hyperbaric Oxygenation


Neurovascular Regeneration:

HBOT mobilizes the body’s circulating stem cells. American Journal Physiology – Heart and Circulatory Physiology (Nov 05)] reports a single 2-hour exposure to HBOT at 2 ATA doubles circulating CD34+ progenitor stem cells (primordial cells targeted to salvage and restore damaged structures); and at approx. 20-hours of HBOT; circulating CD34+ cells increases eight fold (800%).
