Intensive Care Unit or ICU- A specialized area of the hospital where critically ill patients can be closely monitored by specially trained staff.
Intermediate Care Unit or ICR - A patient care area where patients who require close monitoring, or medical and nursing care can be treated.
Intracranial Pressure (ICP) – Pressure in the head (within the cranial cavity).
Intracranial Pressure Monitor (Bolt, ICP monitor, Ventric, Ventriculostomy) –A device inserted through the skull to monitor the pressure in the brain or to drain extra fluid/blood.
Intubate – To insert a tube that can be used to assist the patient with his or her breathing.
Liver – A body organ, located on the right side of the body under the rib cage. Its main functions relate to metabolism, the immune system and blood clotting.
Living Will – A legal document listing a patient’s wishes to receive or refuse medical treatments (similar to Advanced Directives).
Multi-Trauma - An injury to more than one body system.
Myocardial Infarction (MI) – Heart attack.
Magnetic Resonance Imaging (MRI) – A test that can provide images of a bone or a body area, by using magnets rather than x-rays or radioactive materials.
Nasogastric/Orogastric Tube (NG, OG) – Small plastic tubing inserted through the nose or mouth to deliver nourishment to or remove fluid or air from the stomach.
Neurologic – Anything having to do with the brain, spinal cord or nerves.
Oximeter (Pulse-OX) – A device that measures blood oxygen levels through the skin.
Oxygen (O2) – A molecule necessary for breathing and healing. The amount may need to be increased for patients with specific injuries.
Paralysis – A patient’s inability to move voluntarily, either completely or partially; can be temporary or permanent.
Parenteral Nutrition (TPN) – An intravenous solution of calories, protein, vitamins and minerals, given when the intestinal tract cannot be used for nourishment.
Patient Controlled Analgesia (PCA) – A device allowing patients to administer the amount of pain medication they want to receive.
