Hyperoxia
Hyperoxia
Hyperoxia (pronounced: hi-per-ox-ee-uh) is a medical condition characterized by an excess level of oxygen in the body tissues.
Etymology
The term "Hyperoxia" is derived from the Greek words "hyper" meaning "over" and "oxia" referring to "oxygen".
Definition
Hyperoxia occurs when the body's tissues and organs are exposed to an excess supply of oxygen (O2) or higher than normal partial pressures of oxygen. This condition can occur in various medical and clinical settings, such as during oxygen therapy or in a hyperbaric oxygen chamber.
Causes
Hyperoxia is typically caused by breathing air or oxygen at pressures greater than normal atmospheric pressure. This can occur during oxygen therapy, in a hyperbaric chamber, or at high altitudes.
Symptoms
Symptoms of hyperoxia can vary depending on the severity of the condition and the length of exposure to high oxygen levels. They may include pulmonary edema, seizures, and vision changes.
Treatment
Treatment for hyperoxia primarily involves reducing the exposure to high levels of oxygen. This may involve adjusting the settings on an oxygen concentrator or ventilator, or moving the patient to a lower altitude or out of a hyperbaric chamber.
