HBOT: Physician’s Guide

Nirvana has successfully treated hundreds of patients, referred to us from not just the Santa Ynez Valley, but from all over Santa Barbara & San Luis Obispo Counties and beyond.  We make the patient referral process simple... you refer, we handle everything from there.   We accept most major health insurance.  We give your patients the ultimate in care and comfort while making certain they get the treatment they require.  At the same time we will keep you fully informed as to the patients progress throughout the treatment protocol.  

We can provide extensive information and specific case studies for physicians, providers and patients on most any topic or condition.  Many of those studies you'll find on our case studies page, or contact us for assistance and we can get you all the information you seek.

Hyperbaric oxygen (HBOT) is the administration of 100% oxygen at higher than 1.4 atmospheres of pressures while the patient is fully enclosed in a hyperbaric chamber. This causes oxygen to dissolve into the plasma resulting in up to a 20 fold increase in arterial oxygen pressure.  The length of treatment is usually 90 minutes and the number of treatments range from a few to over 40 depending on the protocol for the treating condition.  Treatments are administered consecutively 5 days per week.

HBOT speeds the body’s natural ability to heal by increasing the blood supply (angiogenesis) and fighting infection through the following mechanisms: stem cell production, improved mitochondrial ATP generation, new blood vessel formation (angiogenesis) for improved wound and bone healing, and improved immune activity during chronic infections.

Safety of HBOT

Hyperbaric oxygen therapy is safe for all conditions except for untreated pneumothorax. (29) Certain chemotherapy drugs are contraindicated during HBOT treatment.

Efficacy of HBOT

HBOT has been studied in thousands of clinical, in vivo and in vitro studies and has been shown to be both safe and effective for dozens of disorders. The following section lists all the indications for HBOT, the insurance-reimbursed indications as well as citations of clinical studies for the most common indications.

The following is a list of diagnoses and conditions treated by hyperbarics that are typically covered by health insurance:

Conditions related to cancer treatments and radiation damage
Infections in tissue, muscle, bone or skin, and/or drug resistant infections
Sores and gangrene that will not heal or that are related to diabetes
Surgical sites with grafts or flaps
Bones and/or tissue that are difficult to heal
Acute severe problems from accidents (e.g. crushed leg, arm, fingers)
Rare conditions such as decompression sickness, anemia, burns, carbon monoxide poisoning, or emboli from air or gas
Swelling of the brain, cerebral edema

Atmospheric vs. Hyperbaric oxygen therapy

Normally, when we consider the role of oxygen in medicine it is primarily for hypoxia due to cardiopulmonary indications, such as congestive heart failure, COPD, or pneumonia. Oxygen, carried by hemoglobin in red blood cells, is limited by how much it can increase tissue oxygenation due to rapid saturation of hemoglobin. 

HBOT uses 100% oxygen in a pressurized chamber at 1.5 atm or greater, creating up to a 20-fold increase in oxygen delivery to cells. The key to the effects of hyperbaric oxygen is that it increases the amount of dissolved oxygen in plasma, which has several advantages for patients:

  • Oxygen Delivery: Oxygen dissolved in plasma can be delivered to cells independently of oxygen dissociation factors required by hemoglobin such as 2,3- DPG, acidosis and elevated body temperature
  • Oxygen Perfusion: dissolved oxygen allows for oxygen to be delivered to the microvasculature where red blood cells could not due to:
  1. Altered distensibility, making it useful for sickle cell anemia (1, 2)
  2. Blood rheology, improving oxygenation in the face of thromboemboic phenomenon
  3. Abnormal vasculature improving perfusion in patients with diabetes (3-6), cancer (7-11), cardiovascular disorders (12-14)
  4. Compromised perfusion: traumatic brain injury15, stroke16, CHF12-14
  • Circulation: HBOT increases peripheral vascular dilation through nitric oxide production (4, 13, 14, 17)
  • Stem Cells: Increases stem cell production through nitric oxide production (17)
  • Immunity: Improves oxidative burst capacity, improving native anti-microbial function, particularly in chronic infections (Lyme’s disease18), and acute, aggressive infections (Necrotizing infections19-21)
  • Cancer:
  1. Improves natural killer cell activity against cancer cells22
  2. Potentiates oxidative effects of chemotherapy and radiation therapy and improves quality of life in cancer patients (7- 11)
  • Wound Healing: (3-5, 8, 20, 21, 23, 24) :Improves fibroblast production23, angioneogenesis (6, 12)
  • Sports Injuries: HBOT improves muscle recovery and reduces healing time (25)
  • Neuro-Degenerative disorders: Improves ATP production in mitochondria which improves degenerative disorders: Autism (26, 27), Alzheimer’s, Muscular dystrophies (28)
