Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that makes it difficult to breathe. COPD is a common condition that affects millions of people worldwide and is often caused by smoking. COPD can cause a range of symptoms, including shortness of breath, coughing, and wheezing.

While there are various treatment options available for COPD, some patients may find that hyperbaric oxygen therapy (HBOT) can help alleviate their symptoms.

Hyperbaric oxygen therapy is a medical treatment that involves breathing pure oxygen in a pressurized chamber. The increased pressure and oxygen levels in the chamber can promote healing and reduce inflammation in the body.

HBOT has been used to treat a range of medical conditions, including decompression sickness, carbon monoxide poisoning, and non-healing wounds.

Some studies have suggested that HBOT may also be beneficial for patients with COPD. In this article we’re going to examine what these studies are and what researches say about Hyperbaric Oxygen Therapy for COPD.

Understanding COPD

Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease that causes breathing difficulties. It is characterized by the narrowing of the airways, making it harder for air to flow in and out of the lungs.

COPD is a progressive disease, which means it worsens over time. It is a major cause of morbidity and mortality worldwide.

The primary risk factor for COPD is smoking. Exposure to air pollution, occupational dust and chemicals, and genetic factors can also increase the risk of developing COPD.

The symptoms of COPD include shortness of breath, coughing, wheezing, and chest tightness. These symptoms can significantly impact a person’s quality of life.

COPD is typically classified into two types: chronic bronchitis and emphysema.

Chronic bronchitis is characterized by inflammation of the airways, leading to excessive mucus production and a chronic cough.

Emphysema is characterized by damage to the air sacs in the lungs, leading to reduced lung function and shortness of breath.

Currently, there is no cure for COPD. Treatment aims to relieve symptoms and slow the progression of the disease.

This can include medications such as bronchodilators and steroids, oxygen therapy, and pulmonary rehabilitation. Lifestyle changes such as quitting smoking and avoiding air pollution can also help manage COPD.

In recent years though, hyperbaric oxygen therapy (HBOT) has emerged as a potential treatment for COPD. While HBOT has shown promise in treating other conditions such as carbon monoxide poisoning and decompression sickness, its effectiveness in treating COPD is still being studied.

Hyperbaric Oxygen Therapy: An Overview

Hyperbaric Oxygen Therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized chamber. The therapy has been used to treat a variety of conditions, including decompression sickness, carbon monoxide poisoning, and wounds that won’t heal.

The therapy works by increasing the amount of oxygen in the blood, which can help damaged tissues heal more quickly. The increased oxygen also helps fight off infections and stimulates the growth of new blood vessels.

While HBOT has been used to treat a variety of conditions, including COPD, the therapy is not a cure-all. It is also important to note that the therapy is not a replacement for traditional treatments, such as medication and lifestyle changes.

There are some potential risks associated with HBOT, including ear injuries, lung damage, and seizures. It is important for patients to discuss the risks and benefits of the therapy with their doctor before undergoing treatment.

The Science Behind Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized chamber. The basic principle behind HBOT is to increase the amount of oxygen that can be dissolved in the plasma, thus improving tissue oxygenation and promoting healing.

During HBOT, patients breathe 100% oxygen at a pressure higher than sea level atmospheric pressure. This increases the partial pressure of oxygen in the arterial blood, which in turn increases the amount of oxygen that can be dissolved in the plasma. This extra oxygen is then delivered to the tissues, even in areas with poor blood flow.

The increased oxygenation provided by HBOT has been shown to have a number of therapeutic benefits, including

reducing inflammation
promoting angiogenesis
enhancing tissue repair.

It has been used to treat a wide range of conditions, including:

diabetic foot ulcers
carbon monoxide poisoning
decompression sickness

HBOT has also been studied as a potential treatment for chronic obstructive pulmonary disease (COPD). While the evidence is limited, some studies have suggested that HBOT may improve lung function and quality of life in people with COPD.

What is the difference between Hyperbaric Oxygen Therapy and Oxygen Therapy?

Hyperbaric Oxygen Therapy (HBOT) and Oxygen Therapy are both approaches that involve delivering oxygen to patients, but they differ in their methods and applications, particularly in relation to Chronic Obstructive Pulmonary Disease (COPD).

Hyperbaric Oxygen Therapy (HBOT)

HBOT involves breathing pure oxygen in a pressurized chamber, typically at pressures greater than sea level atmospheric pressure. This allows the oxygen to dissolve more effectively in the bloodstream, promoting its delivery to tissues, even those with compromised blood flow. HBOT is often used to treat conditions like decompression sickness, non-healing wounds, and certain infections, as well as to aid tissue healing.

In the context of COPD, HBOT has been explored as a potential therapy. The idea is that by delivering oxygen at high pressure, it might help deliver oxygen to damaged lung tissue and promote healing. However, research on the effectiveness of HBOT for COPD is still ongoing, and the results are mixed. Some studies suggest modest improvements in lung function, while others have not consistently demonstrated significant benefits.

Oxygen Therapy

Oxygen therapy, on the other hand, involves delivering supplemental oxygen to individuals who have difficulty getting enough oxygen from the air due to lung diseases like COPD. This can be done through various devices, such as nasal cannulas, masks, or portable oxygen tanks. Oxygen therapy aims to increase the oxygen levels in the blood, alleviate shortness of breath, and improve overall oxygen supply to the body’s organs.

Oxygen therapy is a standard treatment for COPD. In COPD, the airways are narrowed, and lung tissue is damaged, leading to reduced oxygen exchange. Supplemental oxygen helps improve oxygen levels in the blood, making it easier for the body to function and reducing the workload on the heart.

KEY TAKEAWAY
while both Hyperbaric Oxygen Therapy (HBOT) and Oxygen Therapy involve oxygen delivery, they differ in their methods and applications. HBOT involves breathing pure oxygen under increased pressure and is explored for various medical conditions, including COPD. Oxygen Therapy, on the other hand, provides supplemental oxygen to improve oxygen levels in the blood and is a common treatment for COPD to alleviate symptoms and enhance overall well-being.

Hyperbaric Oxygen Therapy For COPD: What Expert Say

While there is no cure for COPD, there are several treatments available that can help manage the symptoms and slow the progression of the disease. One of these treatments is hyperbaric oxygen therapy (HBOT).

In this section I am going to examine all the scientific literature around HBOT and COPD.

HBOT’s Effect on Lungs

A study published in BMC Pulmonary Medicine examined the effects of hyperbaric oxygen therapy (HBOT) on lung function using the current treatment protocol. Patients underwent 60 daily HBOT sessions, each involving 100% oxygen at 2 ATA, five days a week.

Lung function tests were conducted before and after the sessions. The findings revealed that, apart from a slight and statistically significant increase in forced vital capacity (FVC) and peak expiratory flow rate (PEF), there were no notable changes in key lung function parameters.

This study concluded that the HBOT protocol seemed to be safe for lung function, demonstrating minor improvements in patients without chronic lung conditions.

Expert Views on Hyperbaric Oxygen Therapy Safety for COPD Patients

A question on the HealthTap medical Q&A website inquired about the safety of hyperbaric oxygen therapy (HBOT) for individuals with COPD. Several doctors responded with varying viewpoints.

Dr. Robin Dretler noted that the increased pressure in the lungs during HBOT could potentially cause lung collapse in individuals with fragile air-filled sacks (blebs) due to COPD.
Dr. George Ciechanowski mentioned the possibility of a fatal event in COPD patients who retain carbon dioxide during hyperbaric diving.
Dr. Saptarshi Bandyopadhyay expressed uncertainty, mentioning that while there’s anecdotal evidence of potential issues with high oxygen concentrations and lung vulnerabilities, this hasn’t been consistently observed. He suggested evaluating each case individually.

Pulmonary Function During Hyperbaric Oxygen Therapy

In a study spanning from 2016 to 2021, researchers evaluated the impact of modern hyperbaric oxygen therapy (HBOT) protocols on pulmonary function. Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working.

Patients underwent 100% oxygen HBOT at 2.0–2.4 atmospheres for 90 minutes, five times weekly. No significant changes were found in pulmonary function tests after 20, 40, or 60 HBOT sessions. Even when considering pre-existing respiratory conditions, smoking history, and treatment pressure, no notable alterations in lung function emerged.

The study implies that contemporary HBOT protocols do not seem to pose a substantiated risk of pulmonary oxygen toxicity, and lung function remained steady even in patients with respiratory diseases.

KEY TAKEAWAY
HBOT is not a cure for COPD, and it should not be used as a stand-alone treatment. Instead, it should be used in conjunction with other treatments, such as medication and pulmonary rehabilitation. Additionally, HBOT may not be suitable for all patients with COPD, and it should only be used under the guidance of a healthcare professional.

Benefits of Hyperbaric Oxygen Therapy for COPD Patients

Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing in pure oxygen while inside a pressurized chamber. This therapy has been found to be beneficial for patients with various medical conditions, including chronic obstructive pulmonary disease (COPD).

Here are some of the benefits of HBOT for COPD patients:

Improved Oxygenation

COPD patients often have difficulty breathing due to damaged lung tissue and reduced lung function. HBOT can help improve oxygenation by increasing the amount of oxygen in the blood and tissues. This can help reduce shortness of breath and improve exercise tolerance in COPD patients.

Reduced Inflammation

Inflammation is a common symptom of COPD, and it can cause further damage to the lungs. HBOT has been found to reduce inflammation in the body, which can help alleviate COPD symptoms and slow down the progression of the disease.

Enhanced Healing

COPD patients are at increased risk of developing infections, which can further worsen their condition. HBOT has been found to enhance the body’s healing process by increasing blood flow and oxygen delivery to damaged tissues. This can help reduce the risk of infections and improve overall lung function.

Improved Quality of Life

COPD can significantly impact a patient’s quality of life, making it difficult to perform daily activities and enjoy hobbies. HBOT has been found to improve quality of life in COPD patients by reducing symptoms and improving lung function. This can help patients regain their independence and enjoy a better quality of life.

Risks and Side Effects

Hyperbaric oxygen therapy (HBOT) is generally considered safe, but there are some risks and side effects associated with it, particularly for patients with chronic obstructive pulmonary disease (COPD).

One of the main concerns is the potential for pulmonary barotrauma (PBT) from lung overinflation during decompression. Patients with active bronchospasm, air trapping, or bullae are at higher risk for PBT.

In addition, patients with a history of severe asthma, emphysema, or other COPD are at risk for formation of a tension pneumothorax, which can be life-threatening.

Other potential side effects of HBOT include ear barotrauma, sinus barotrauma, and dental barotrauma. These occur when changes in pressure cause damage to the ear, sinuses, or teeth. Patients may also experience claustrophobia, anxiety, or fatigue during treatment.

Oxygen toxicity is another potential risk of HBOT. This occurs when patients are exposed to high levels of oxygen for an extended period of time. Symptoms of oxygen toxicity may include seizures, vision changes, and breathing difficulties.

Overall, the risks and side effects of HBOT are relatively low, but patients with COPD should be carefully evaluated before undergoing treatment. It is important for patients to discuss any concerns or medical conditions with their healthcare provider before starting HBOT.

Conclusion

In conclusion, hyperbaric oxygen therapy (HBOT) has been shown to have potential benefits for patients with chronic obstructive pulmonary disease (COPD). However, the evidence is limited and conflicting.

Some studies suggest that HBOT can improve lung function, exercise capacity, and quality of life in patients with COPD, while others have found no significant benefits.

Further research is needed to fully understand the potential benefits and risks of HBOT for COPD. Until then, it is recommended that patients with COPD consult with their healthcare provider before considering HBOT and only receive treatment from a qualified healthcare professional in a safe and controlled environment.

Overall, while HBOT may hold promise as a complementary therapy for COPD, more research is needed to determine its effectiveness and safety.
