Oxygen is essential for life. It produces energy and removes toxins from our body. Oxygen therapy heals wounds, increases the quality of life, and also extends lifespan. Continue reading to learn more about how oxygen therapy can improve your health.

Oxygen therapy is the use of supplemental oxygen to treat a variety of medical conditions. There are two main types of oxygen therapies available:
- Normobaric oxygen therapy
- Hyperbaric oxygen therapy
Normobaric oxygen therapy is supplemental oxygen administered at the same pressure of our atmosphere (1 atm). Depending on the medical condition, 40 to 100% of saturated oxygen is delivered to the body.
As excessive oxygen can be harmful, normobaric oxygen therapy should be regulated. In the absence of correct medical supervision, normobaric oxygen therapy can also cause heart disease, inflammation, diabetes, and aging [R].
Hyperbaric oxygen therapy is 100% saturated supplemental oxygen delivered at higher atmospheric pressures. Patients are placed in a high pressure, full body chamber (hyperbaric chamber). This increases oxygen delivery to all of the tissues of the body [R].
Treatment schedules of hyperbaric oxygen therapy vary between 60 to 120 minutes, 1 or more times daily [R].
Hyperbaric oxygen therapy is approved for the treatment of a number of conditions such as air or gas embolisms, burns, diabetic wounds, and traumatic ischemia.
Mechanism of Oxygen Therapy
Blood is made up of 4 components: plasma, red blood cells, white blood cells, and platelets. Oxygen is transported through red blood cells that contain the protein hemoglobin. Hemoglobin is an iron-containing protein that oxygen can bind to [R].
The only differences between normobaric and hyperbaric oxygen therapy are the pressure that they’re applied at and the method of delivery. Both forms of therapy increase the amount of oxygen that is delivered in the blood [R].
Normobaric oxygen therapy increases binding of oxygen with blood hemoglobin [R].
Titrated normobaric oxygen therapy improves blood oxygen levels [R].
Increasing the delivery of oxygen to the body supports the healing process of damaged tissues.
Health Benefits of Oxygen Therapy
1) Oxygen Therapy Can Improve Lung Failure
Acute lung failure is a condition that is caused by choppy or labored inhaling, causing low blood oxygen levels [R].
A meta-analysis including 703 patients (RCTs) concluded that emergency normobaric oxygen therapy increased the number of patients recovering from life-threatening acute lung failure [R].
A multicenter analysis (RCTs) of patients with lung failure indicated that normobaric oxygen therapy cleared the upper airways, improved lung function, and reduced pressure on the lungs [R].
2) Oxygen Therapy is Beneficial for Asthma
Asthma obstructs airways in lungs and can cause low blood oxygen (hypoxemia) leading to severe health complications.
In 106 patients with severe asthma (RCT), normobaric oxygen therapy for 2 years increased survival of patients and reduced symptoms [R].
3) Oxygen Therapy Can Improve Symptoms of COPD
Smoking, breathing pollutants, and lack of a specific protein, alpha-1-antitrypsin, causes COPD [R].
Several long-term clinical studies of hundreds of patients with COPD using supplemental normobaric oxygen therapy showed [R]:
- Benefit from exercise and activity
- Reduction of anxiety
- Improved quality of life
- Prolonged lifespan
- Improved sleep quality
An observational study with 195 COPD patients for 6 months indicated that normobaric oxygen therapy improved the quality of life of patients with emphysema [R].
In 86 elderly patients with COPD, normobaric oxygen therapy reduced pressure on the heart blood vessels and improved sleep [R].
4) Oxygen Therapy is Beneficial for Cystic Fibrosis
Cystic fibrosis is a genetic condition caused by the lack of the CFTR gene. People with cystic fibrosis suffer from breathing problems [R].
A review of 11 clinical trials (RCT) with 172 participants found that supplemental normobaric oxygen therapy improved sleep patterns and quality of life [R].
5) Oxygen Therapy May Improve Symptoms of Stroke
Ischemic stroke is caused by a clot in the blood vessels that decreases blood flow to the brain and leads to cell death.
There is limited evidence in humans indicating that normobaric oxygen therapy is beneficial for stroke patients. Oxygen therapy is most beneficial when applied within the first few hours of having a stroke [R].
The importance of prompt treatment is highlighted in an RCT where delayed normobaric oxygen therapy of 40 patients did not improve the outcomes of these patients [R].
Contraindications of Oxygen Therapy
Before using supplemental oxygen therapy, patients must be inspected for pneumothorax. Pneumothorax is caused by the buildup of air in the space between the chest wall and the lungs. If the pneumothorax is unrecognized or untreated, using oxygen therapy could result in the lungs collapsing and ultimately death [R, R].
- Severe claustrophobia
- Febrile illness
- Chronic obstructive pulmonary disease (COPD)
- Seizure disorder
Highly concentrated oxygen can easily catch on fire. Therefore, fires surrounding hyperbaric oxygen chambers, oxygen gas cylinders, tanks, and concentrators are a high risk for danger [R].
Side Effects of Oxygen Therapy
Normobaric is safer than hyperbaric oxygen therapy, although hyperbaric oxygen therapy is more effective.
Despite the risks and side effects, proper use of normobaric and hyperbaric oxygen therapies are considered safe and low-risk interventions [R].
Technicalities of Oxygen Therapy
During normobaric oxygen therapy, oxygen can be delivered as oxygen gas, liquid oxygen, or via oxygen concentrators.
Oxygen gas is compressed in a gas cylinder. Liquid oxygen is stored in portable tanks and is boiled to release oxygen gas. Oxygen gas cylinders are also fitted with regulators that sense a patient’s breathing rate and sends pulses of oxygen.
Oxygen concentrators are devices that take oxygen from the air and concentrate it for use.
Health Tools I Wish I Had When I Was Sick
At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.
That’s why I decided to create tools that will help others cut down the guesswork:
- Lab Test Analyzer – a software tool that will analyze your labs and tell you what the optimal values are for each marker — as well as provide you with actionable tips and personalized health and lifestyle recommendations to help you get there.
- SelfDecode – a software tool that will help you analyze your genetic data from companies such as 23andme and ancestry. You will learn how your health is being impacted by your genes, and how to use this knowledge to your advantage.
- SelfHacked Secrets – an ebook where we examine and explain the biggest overlooked environmental factors that cause disease. This ebook is a great place to start your journey if you want to learn the essential steps to optimizing your health.
