Harch HBOT 

Harch HBOT is the private practice of Dr. Paul Harch, the international expert in hyperbaric oxygen therapy. His treatment program for patients is unmatched. We aim to give people back their lives with hyperbaric oxygen therapy. Located in New Orleans, Louisiana, many patients come to us from outside of the New Orleans area.  In fact, patients from over 50 countries have come to New Orleans to receive HBOT under Dr. Harch’s guidance. Learn more about how Dr. Harch can help you heal with hyperbaric oxygen therapy. 

What is HBOT? 

Hyperbaric oxygen therapy, or HBOT, is a medical treatment that enhances the body’s natural healing processes. It is a simple, non-invasive, and painless treatment. The combination of increased atmospheric pressure and increased percentage of oxygen in a total body chamber treats a wide variety of medical conditions. It is also commonly referred to as oxygen treatment, hyperbaric therapy, or hyperbaric oxygen treatment.

How Does Hyperbaric Oxygen Therapy Work?

Under normal circumstances, oxygen is transported throughout the body by red blood cells with a tiny amount also dissolved in plasma, the liquid portion of the blood. When oxygen is delivered under pressure much greater amounts of oxygen are dissolved in plasma where it is more readily available for transfer to all of the tissues and fluids in the body, such as the central nervous system fluid, the lymphatic system, connective tissue, all solid organs, and bone. In the smallest blood vessels, plasma blood flow carries the increased oxygen to areas where circulation is diminished or blocked. In this way, adequate oxygen can reach all of the damaged tissues, especially those where healing is delayed or diminished. Once sufficient oxygen is delivered to these damaged tissues, the oxygen reduces swelling. This greatly enhances the ability of white blood cells to kill bacteria and stimulates new blood vessels to grow more rapidly into the affected areas.

What Are the Benefits of HBOT? 

There are many benefits of HBOT. Healing cannot take place without appropriate oxygen levels in the tissue and cells. Many illnesses and injuries fail to heal because of inadequate oxygen levels. Increased oxygen under pressure, or HBOT, provides this extra oxygen to tissue and cells with minimal side effects. Some of the many benefits of hyperbaric oxygen therapy include: 

  • New connective tissue growth
  • New blood vessel growth
  • New skin growth
  • Remodeling of bone
  • Expedited healing 
  • New cell regeneration 
  • Anti-aging 
  • A feeling of well being
  • Improved quality of life 

What Conditions Does HBOT Treat? 

Potentially, HBOT can be used for any condition that involves injury, wounding, loss of blood supply, or inflammation. At Harch HBOT, we treat more than 70 conditions with hyperbaric oxygen therapy. The following are some of the most common conditions and injuries that Dr. Harch treats with oxygen therapy.

Even if the condition or injury that you or a loved one is suffering from is not listed here, it does not mean that it is not responsive to HBOT or that we cannot successfully treat you with hyperbaric oxygen therapy. Hyperbaric oxygen therapy is different from all other known therapies in that it treats the underlying disease processes that are responsible for and common to many diseases. Diseases that are similar to those diseases that are typically treated with HBOT are also very often responsive to HBOT. Please contact us today to find out if you or your loved one is a good candidate for HBOT with Dr. Harch.

HBOT for COVID-19 

HBOT is most recently being used to treat COVID-19 and appears to be working well for most coronavirus cases. In early 2020, Dr. Harch announced to the medical community in a post that “History bears remembering.” He noted that the introduction of HBOT in the United States by Dr. Orval Cunninghan in 1918 was to Spanish Flu patients dying of the same lung condition as COVID-19 patients. At the same time, Dr. Xaioling Zhong in Wuhan successfully treated 35 patients with COVID-19, six of whom were deteriorating. Since then, multiple centers have reported the beneficial impact of HBOT on dying COVID-19 patients. Dr. Harch has been successfully treating patients with COVID-19 Long-Haulers Syndrome. Contact us for more details about how HBOT can benefit patients affected by COVID-19. 

What Is a Hyperbaric Chamber? 

A hyperbaric chamber is a fully enclosed vessel in which increased pressure and increased amounts of oxygen are therapeutically delivered.  At Harch HBOT, we use state-of-the-art, monoplace chambers of clear acrylic which have been customized to administer the entire range of clinical hyperbaric oxygen therapy doses.  During a treatment, the increased air pressure in the chamber causes greater than normal amounts of oxygen to dissolve in the blood passing through the lungs. The increased pressure itself also has beneficial effects for patients. Our clear chambers allow our professionally trained technicians to closely monitor the patient and allow the patient to see outside the chamber easily. Patients are able to communicate with the attending technician via an intercom, and they can watch a movie, listen to music, or rest during their treatment. 

Is HBOT Safe?

Overall, hyperbaric oxygen therapy is extremely safe. Hyperbaric oxygen therapy is prescribed by a physician and performed under medical supervision. It is non-invasive, painless, and helps with a wide variety of medical conditions and injuries. However, like all medical treatments, there are some minor risks. The risks will be discussed with you before you sign your consent form for therapy.

How to Get Oxygen Treatment at Harch HBOT 

Oxygen therapy

If you or a loved one are considering receiving hyperbaric oxygen therapy from Dr. Harch at Harch HBOT, we will walk you through our clinic’s process from start to finish. 

First, our patient care coordinator will schedule you for a telephone interview with Dr. Harch. He will review you or your loved one’s medical records and he will discuss the relevant medical history, expectations for HBOT, and confirm that the patient is a good candidate for oxygen therapy. 

Next, you will schedule an intake assessment at our clinic in New Orleans.
