Glossary

Bone Growth Stimulator: A machine that uses either electronic stimulation or ultrasound to heal broken bones.

Bronchosopy: A technique of visualizing the inside of the airways for diagnostic and therapeutic purposes.

Deep Vein Thrombosis: (Usually abbreviated as DVT) is the formation of a blood clot (“thrombus”) in a deep vein.

Electroencephalography (EEG): The recording of electrical activity along the scalp produced by the firing of neurons within the brain.

Electrolytes: Commonly, electrolytes are solutions of acids, bases or salts.

Evoked Response Potential: An electrical potential recorded from the nervous system following presentation of a stimulus, as distinct from spontaneous potentials as detected by electroencephalography (EEG) or electromyography (EMG).

Extubate: To remove a tube from a hollow organ or passageway, often from the airway. The opposite of extubate is intubate.

G-Tube: A gastric feeding tube is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition.

Gastric Residual (Checking): A major nursing responsibility to prevent aspiration in tube-fed for assessing the rate of gastric emptying. This is accomplished by measuring the amount of gastric contents at regular intervals during continuous tube feedings or prior to each intermittent feeding. High residual volumes increase the risk for pulmonary aspiration (the most severe complication of tube feedings).

Hyperbaric Oxygen Therapy (HBOT):  The medical use of oxygen at a level higher than atmospheric pressure.  The therapeutic principle of HBOT lies in its ability to drastically increase partial pressure of oxygen in the tissues of the body. The oxygen

partial pressures achievable using HBOT are much higher than those achievable while breathing pure oxygen at normobaric conditions (i.e. at normal atmospheric pressure); A related effect is the increased oxygen transport capacity of the blood. Under normal atmospheric pressure, oxygen transport is limited by the oxygen binding capacity of hemoglobin in red blood cells and very little oxygen is transported by blood plasma. Because the hemoglobin of the red blood cells is almost saturated with oxygen under atmospheric pressure, this route of transport cannot be exploited any further. Oxygen transport by plasma, however is significantly increased using HBOT as the stimulus.

Intubate: The placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway. The opposite of intubate is extubate.

Oxygen Saturation: (SO2), commonly referred to as “sats”, measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.

PICC Line:peripherally inserted central catheter (PICC or PIC line) is a form of intravenous access that can be used for a prolonged period of time (e.g. for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition).

Propofol: A short-acting, intravenously administered hypnotic agent. Its uses include the induction and maintenance of general anesthesia, sedation for mechanically ventilated adults, and procedural sedation.

Qualitative EEG, or qEEG: A scientifically established method for evaluating brain function based on brain electrical activity mapping. In this form of functional brain imaging, the brain’s electrical activity, as measured in 19 or 25 sites on the head, is analyzed using complex mathematical and statistical tools in comparison to norms or averages.

Sputum Culture: A test to detect and identify bacteria or fungi that infect the lungs or breathing passages.  Sputum is a thick fluid produced in the lungs and in the adjacent airways.

Stridor: a high pitched wheezing sound resulting from turbulent air flow in the upper airway.
