| Term | Definition |
|---|---|
| Embolus | Blood clot, air bubble, piece of fatty deposit or other object which has been carried in the blood stream to lodge in a vessel and cause an embolism. |
| Friction | Effects of rubbing or the resistance that the moving body meets from the surface from which it moves; a force that occurs in a direction to oppose movement. |
| Dehiscence | Separation of the edges of a wound, revealing underlying tissues. |
| Tissue Ischemia | Point at which tissues receive insufficient oxygen and perfusion. |
| Approximated | To come close together as in the edges of a wound. |
| Granulation Tissue | Soft pink fleshy projections of tissue that form during the healing process in a wound not healing by primary intention. |
| Metabolism | Aggregate of all chemical processes that take place in living organisms and result in growth, generation of energy, elimination of water and other functions concerned with the distribution of nutrients in the blood after digestion. |
| Maceration | Softening or breaking down of skin from prolonged exposure to moisture. |
| Body Mass Index (BMI) | A person’s weight in kilograms divided by the square of height in meters. BMI can be used to screen for weight categories that may lead to health problems but it is not diagnostic of the body fatness or health of an individual. |
| Shear | Force exerted against the skin, while the skin remains stationary and the bony structures move. |
| Eschar | Thick layer of dead, dry tissue that covers a pressure ulcer or thermal burn. |
| Blanching | A temporary obstruction of blood flow to the area that causes the color of the area to become pale relative to the surrounding skin. |
| Pressure Ulcers | Inflammation, sore or ulcer in the skin over a bony prominence. |
| Enteral Nutrition (EN) | Provision of nutrients through the GI tract when the patient cannot ingest, chew or swallow food but can ingest nutrients. |
| Parenteral Nutrition (PN) | Administration of a nutritional substance into the vascular system. |
| Hemoptysis | Small amounts of blood mixed with sputum brought up by a forceful cough |
| Kussmaul's Respirations | an increase in both rate and depth of respirations, typically seen in metabolic acidosis, to compensate by decreasing carbon dioxide levels. |
| Cheyne-Stokes Respirations | abnormal respiratory pattern with periods of apnea followed by periods of deep breathing, then shallow breathing, then more apnea. Occurs when there is decreased blood flow or injury to the brain stem. |
| Diaphragmatic breathing | respiration pattern in which the abdomen moves out while the diaphragm descends on inspiration |
| Hematemesis | vomiting of blood, indicating an upper gastrointestinal bleed |
| Incentive spirometry | Method of encouraging voluntary deep breathing by providing visual feedback to patients of the inspiratory volume they have achieved |
| Pneumothorax | collection of air or gas in the pleural space |
| Metabolic acidosis | Abnormal condition of high hydrogen ion concentration in the extracellular fluid caused by either primary increase in hydrogen ions or decrease in bicarbonate |
| Metabolic alkalosis | Abnormal condition characterized by the significant loss of acid from the body or increased levels of bicarbonate |
| Respiratory acidosis | Abnormal condition characterized by increased arterial carbon dioxide concentration, excess carbonic acid, and increased hydrogen ion concentration |
| Respiratory alkalosis | Abnormal condition characterized by deceased arterial carbon dioxide concentration and hydrogen ion concentration |
| Hypotonic | Situation in which one solution has a smaller concentration of solute than another, therefore the first solution exerts less osmotic pressure |
| Hypertonic | Situation in which one solution and a greater concentration of solute than another, therefore the first solution exerts greater osmotic pressure |
| Isotonic | Situation in which two solutions have the same concentration of solute, therefore both solutions exert the same osmotic pressure |
| Phlebitis | the inflammation of a vein |
