  2. Life-support system - Wikipedia

    en.wikipedia.org/wiki/Life-support_system

    The life support system of a surface saturation accommodation facility provides breathing gas and other services to support life for the personnel under pressure. It includes the following components: [ 12 ] Underwater habitats differ in that the ambient external pressure is the same as internal pressure, so some engineering problems are ...

  3. Life support - Wikipedia

    en.wikipedia.org/wiki/Life_support

    Life support comprises the treatments and techniques performed in an emergency in order to support life after the failure of one or more vital organs. Healthcare providers and emergency medical technicians are generally certified to perform basic and advanced life support procedures; however, basic life support is sometimes provided at the scene of an emergency by family members or bystanders ...

  4. Primary life support system - Wikipedia

    en.wikipedia.org/wiki/Primary_Life_Support_System

    A portable life support system from the Apollo A7L suit, with its outer cover removed. A primary (or portable or personal) life support system (or subsystem) (PLSS), is a device connected to an astronaut or cosmonaut's spacesuit, which allows extra-vehicular activity with maximum freedom, independent of a spacecraft's life support system.

  6. Bioregenerative life support system - Wikipedia

    en.wikipedia.org/wiki/Bioregenerative_life...

    Bioregenerative life support systems (BLSS) are artificial ecosystems consisting of many complex symbiotic relationships among higher plants, animals, and microorganisms. As the most advanced life support technology, BLSS can provide a habitation environment similar to Earth's biosphere for space missions with extended durations, in deep space ...

    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.

  8. Controlled ecological life-support system - Wikipedia

    en.wikipedia.org/wiki/Controlled_ecological_life...

    The life of such a system is limited, as the entropy of a closed system can only increase with time. But if the otherwise closed system is allowed to accept high-temperature radiant energy from an external source (e.g., sunlight) and to reject low-temperature waste heat to deep space, it can continue indefinitely.

  9. Basic life support - Wikipedia

    en.wikipedia.org/wiki/Basic_Life_Support

    Basic Life Support Emergency Medical Services in the United States are generally identified with Emergency Medical Technicians-Basic (EMT-B). EMT-B is the highest level of healthcare provider that is limited to the BLS protocol; higher medical functions use some or all of the Advanced Cardiac Life Support (ACLS) protocols, in addition to BLS ...
