What You Should Know About Excess Oxygen within Blood

Oxygen is essential for cells to exist; without oxygen, there will be brain damage within three minutes. So in the treatments of traumas such as stroke or heart attack, patients are provided with oxygen to avoid brain damage. However, resuscitating the patient with excess amounts of oxygen will have a net negative effect. It will cause hyperoxemia, a condition that there is an incredibly high amount of oxygen in the blood. Read on to learn more about the situation.

What Are the Effects of Too Much Oxygen in Blood?

Patients who are susceptible to hyperoxemia include astronauts, scuba divers, and people undergoing hyperbaric oxygen therapy. When they inhale too much of oxygen, symptoms such as nausea, tunnel vision, and inflammation of the airways may occur.

According to the level of exposure to excess oxygen, there are different forms of hyperoxemia. CNS or central nervous system damage mostly occurs when there are high pressure and short duration of excess oxygen in blood. It can lead to twitching, dizziness, nausea, seizures and in severe cases death. On the other hand, pulmonary or ocular problems may occur if there is a long-term exposure to oxygen at normal atmospheric pressure. The symptoms include inflammation of the lungs, difficulty in breathing, coughing and fever.

How to Avoid Too Much Oxygen in Blood While Diving

To avoid excess oxygen in blood, astronauts should undergo proper training to curb this problem. These people need to learn how to utilize oxygen spacesuits under different atmospheric pressures. For patients undergoing hyperbaric oxygen treatment, they should be regularly monitored for excess or elevated levels of oxygen. Here is mainly about how to avoid inhaling excess oxygen while diving.
