2. Hypoxic air technology for fire prevention - Wikipedia

   en.wikipedia.org/wiki/Hypoxic_air_technology_for...

   Some oxygen reduction systems are integrated with traditional fire detection systems (e.g., smoke detectors or heat sensors) for an additional layer of protection. Ventilation Control Systems : In some installations, ventilation systems (or air-conditioning systems) may be used to adjust the airflow and maintain a stable atmosphere within the ...

3. Immediately dangerous to life or health - Wikipedia

   en.wikipedia.org/wiki/Immediately_dangerous_to...

   The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or hypo-baric or submerged chambers, etc.).

4. Hypoxemia - Wikipedia

   en.wikipedia.org/wiki/Hypoxemia

   Hypoxemia is usually defined in terms of reduced partial pressure of oxygen (mm Hg) in arterial blood, but also in terms of reduced content of oxygen (ml oxygen per dl blood) or percentage saturation of hemoglobin (the oxygen-binding protein within red blood cells) with oxygen, which is either found singly or in combination.

   en.wikipedia.org/wiki/ISS_ECLSS

   The interactions between the components of the ISS Environmental Control and Life Support System (ECLSS) The International Space Station (ISS) Environmental Control and Life Support System (ECLSS) is a life support system that provides or controls atmospheric pressure, fire detection and suppression, oxygen levels, proper ventilation, waste management and water supply.

6. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   Oxygen deficiency gas monitors are used for employee and workforce safety. Cryogenic substances such as liquid nitrogen (LN2), liquid helium (He), and liquid argon (Ar) are inert and can displace oxygen (O 2) in a confined space if a leak is present. A rapid decrease of oxygen can provide a very dangerous environment for employees, who may not ...

7. CO-oximeter - Wikipedia

   en.wikipedia.org/wiki/CO-oximeter

   Finger tip carboxyhemoglobin saturation monitor.. A CO-oximeter is a device that measures the oxygen carrying state of hemoglobin in a blood specimen, including oxygen-carrying hemoglobin (O2Hb), non-oxygen-carrying but normal hemoglobin (HHb) (formerly, but incorrectly, referred to as 'reduced' hemoglobin), as well as the dyshemoglobins such as carboxyhemoglobin (COHb) and methemoglobin (MetHb).
