Hyperoxia is the state of being exposed to high levels of oxygen; it may refer to organisms, cells and tissues that are experiencing excessive oxygenation, [1] or to an abnormally high oxygen concentration in an environment (e.g. a body of water).

Experimental models and volunteer and patient studies demonstrate that hyperoxia (and hypoxia) can induce pro- and anti-inflammatory responses, with both protective and harmful sequelae [17].

2021年12月19日 · Experimental models and volunteer and patient studies demonstrate that hyperoxia (and hypoxia) can induce pro- and anti-inflammatory responses, with both protective and harmful sequelae [17]. Hyperbaric oxygen is used to aid wound healing and treat gas gangrene, but may cause neurotoxicity.

Hyperoxia is a state of excess supply of O 2 in tissues and organs. Oxygen toxicity occurs when the partial pressure of alveolar O 2 (P A O 2) exceeds that which is breathed under normal conditions. With continuous exposure to supraphysiologic concentrations of O 2, a state of hyperoxia develops.

A hyperoxia test is a test that is performed—usually on an infant—to determine whether the patient's cyanosis is due to lung disease or a problem with blood circulation.

hyperoxia， 英语单词，主要用作为名词，意为（组织内）氧过多。 hyperoxia liquid 高氧液. hyperoxia solution 高氧液. hypertonic and hyperoxia 高渗高氧. venous hyperoxia liquid 静脉高 …

Hyperoxia involves the administration of high concentrations of inspired oxygen to the lung. Hyperoxemia reflects high levels of oxygen in the blood. In general, a PaO2 >100 mm Hg/13.3 kPa reflects hyperoxia. Hyperoxia leads to development of reactive oxygen species (ROS).

Physiological effects of hyperoxia include inhibition of hypoxic pulmonary vasoconstriction, promotion of atelectasis, and systemic vasoconstriction. Adverse clinical effects of hyperoxia occur, including increased mortality, in intensive care, …

Hyperoxia describes any situation when cells, tissues, or organs are exposed to oxygen at a higher than normal partial pressure.

2018年7月1日 · Hyperoxia has also been used liberally by athletes in a belief that it offers performance-enhancing benefits; such benefits also extend to hypoxemic patients both at rest and during rehabilitation. This review aims to provide a comprehensive overview of the effects of hyperoxia in humans from the "bench to bedside."
