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 make this direct statement to the American people that there is far less chance of the United States getting into war, if we do all we can now to support the nations defending themselves against attack by the Axis than if we acquiesce in their defeat, submit tamely to an Axis victory, and wait our turn to be the object of attack in another war later on.
    Franklin D. Roosevelt (1882–1945)

    The destructive character lives from the feeling, not that life is worth living, but that suicide is not worth the trouble.
    Walter Benjamin (1892–1940)
