Life Support

The critical systems are the atmosphere control system, the water supply system, the food supply facilities, the sanitation and hygiene equipment, and fire detection and suppression equipment. The Russian orbital segment's life support systems are contained in the Service Module Zvezda. Some of these systems are supplemented by equipment in the USOS. The MLM Nauka laboratory has a complete set of life support systems.

Life Support

Life support in medicine is a broad term that applies to any therapy used to sustain a patient's life while they are critically ill or injured, as part of intensive-care medicine. There are many therapies and techniques that may be used by clinicians to achieve the goal of sustaining life. Some examples include:

  • Feeding tube
  • Total parenteral nutrition
  • Mechanical ventilation
  • Heart/Lung bypass
  • Urinary catheterization
  • Dialysis
  • Cardiopulmonary resuscitation
  • Defibrillation
  • Artificial pacemaker

These techniques are applied most commonly in the Emergency Department, Intensive Care Unit and, Operating Rooms. As various life support technologies have improved and evolved they are used increasingly outside of the hospital environment. For example a patient who requires a ventilator for survival are commonly discharged home with these devices. Another example includes the now ubiquitous presence of Automated external defibrillator in public venues which allow lay people to deliver life support in a prehospital environment.

The ultimate goals of life support depend on the specific patient situation. Typically life support is used to sustain life while the underlying injury or illness is being treated or evaluated for prognosis. Life support techniques may also be used indefinitely if the underlying medical condition cannot be corrected but a reasonable quality of life can still be expected.


Famous quotes containing the words support and/or life:

    I believe, as Maori people do, that children should have more adults in their lives than just their mothers and fathers. Children need more than one or two positive role models. It is in your children’s best interest that you help them cultivate a support system that extends beyond their immediate family.
    Stephanie Marston (20th century)

    My love lies underground
    With her face upturned to mine,
    And her mouth unclosed in a last long kiss
    That ended her life and mine.
    —D.H. (David Herbert)
