Hypobaric chamber at the Biopol'H, in Catalonia (), used with patients and athletes who need treatment or training with reduced atmospheric pressure. A hypobaric chamber, or altitude chamber, is a chamber used during aerospace or high terrestrial altitude research or training to simulate the effects of high altitude on the human body, especially hypoxia (low oxygen) and hypobaria (low ambient ...
Intermittent hypoxic training (IHT), also known as intermittent hypoxic therapy, is a technique aimed at improving human performance by way of adaptation to reduced oxygen. An IHT session consists of an interval of several minutes breathing hypoxic (low oxygen) air, alternated with intervals breathing ambient (normoxic) or hyperoxic air.
An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are also used industrially and as medical devices for oxygen therapy. [15] Two methods in common use are pressure swing adsorption and membrane gas ...
Oxygen therapy is the use of supplemental oxygen as medical therapy. [46] Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity, cluster headache and decompression illness. It may also be prophylactically given to maintain blood oxygen levels during the induction of anesthesia. [47]
For example, at high altitude, the arterial oxygen P a O 2 is low, but only because the alveolar oxygen P A O 2 is also low. However, in states of ventilation perfusion mismatch , such as pulmonary embolism or right-to-left shunt , oxygen is not effectively transferred from the alveoli to the blood which results in an elevated A-a gradient.
Athletes training at high altitude in St. Moritz, Switzerland (elevation 1,856 m or 6,089 ft). Athletes can also take advantage of altitude acclimatization to increase their performance. [10] The same changes that help the body cope with high altitude increase performance back at sea level. However, this may not always be the case.

The alveolar oxygen is transferred to hemoglobin, a carrier protein inside red blood cells, with an efficiency that decreases with the partial pressure of oxygen in the air. Altitude. The external partial pressure of oxygen decreases with altitude, for example in areas of high altitude or when flying.
