You probably learned a long time ago that 1) We need oxygen to survive, and 2) Our bodies transport oxygen by using red blood cells. In many cases, this process works fine. We breathe in air through our lungs. That oxygen is then transported through the blood and delivered to the rest of our bodies.

However, poor circulation or blockage can prevent oxygen from reaching certain areas of a person’s body. This can cause a condition called hypoxemia, which is low oxygen in tissues. Symptoms can include sweating, wheezing, fast heart rate, confusion and changes in skin color, according to News Medical. And this condition can be caused by severe asthma attacks, lung diseases, heart issues and anemia.

“If someone experiences hypoxemia, he or she should receive immediate medical assistance.”

If someone experiences hypoxemia, he or she should receive immediate medical assistance. While at the hospital, doctors will administer oxygen into the patient’s body right away, according to Charles Davis, MD, writing for Although the patient receives the necessary amount of oxygen to bring levels back to normal, the following problem may occur later: His or her oxygen level could drop again. Naturally, there may be no way to keep oxygen amounts stable, but this could be done by using a procedure called hyperbaric oxygen therapy.

HBOT is an alternative treatment, not administered in hospitals, that increases the amount of oxygen in a person’s tissues. When using this method to treat for oxygen deficiency, a patient sits or rests in a roomy, pressurized device called the Vitaeris 320. While in this machine, he or she breathes pure oxygen for about an hour. This procedure ensures oxygen is equally absorbed into all parts of the body, and, from there, it can be carried to locations that need more.

HBOT is a versatile procedure that solves multiple health issues by getting to the root of the initial problem: a lack of oxygen. Author Hesh Goldstein of Natural News brought up an obvious but very good point when he noted that a person’s body simply won’t operate without oxygen. The body requires oxygen to naturally heal wounds, our cells need it to redevelop and our brain relies on it to help us think. HBOT reintroduces oxygen into a person to help him or her function on a daily basis and manage and prevent serious conditions.

In general, the Department of Anesthesia at the University of Iowa noted there are few serious health side effects when using HBOT. If a patient typically doesn’t enjoy tight spaces, he or she may be put off by the chambers slightly small quarters. Although, most devices should be able to fit upwards of two people.
