Breath-hold diving involves environmental challenges, such as water immersion, hydrostatic
pressure, and asphyxia, that put the respiratory system under stress. While training and …

Hyperbaric oxygen therapy (HBOT) is a therapeutical approach based on exposure to pure
oxygen in an augmented atmospheric pressure. Although it has been used for years, the …

Long COVID-19 patients show systemic inflammation and persistent symptoms such as
fatigue and malaise, profoundly affecting their quality of life. Since improving oxygenation …

Exercise generates reactive oxygen species (ROS), creating a redox imbalance towards
oxidation when inadequately intense. Normobaric and hyperbaric oxygen (HBO) breathed …

Oxygen is a powerful trigger for cellular reactions and is used in many pathologies, including
oxidative stress. However, the effects of oxygen over time and at different partial pressures …

Concordia Station is the permanent, research station on the Antarctic Plateau at 3230 m.

In this study, the metabolic responses of hypoxic breathing for 1 h to inspired fractions of
10% and 15% oxygen were investigated. To this end, 14 healthy nonsmoking subjects (6 …

Saturation diving allows divers to reduce the risk of decompression sickness while working
at depth for prolonged periods but may increase reactive oxygen species (ROS) production …

Purpose Divers can experience cognitive impairment due to inert gas narcosis (IGN) at
depth. Brain-derived neurotrophic factor (BDNF) rules neuronal connectivity/metabolism to …
