TERMINOLOGY III
1. Definitions and Concepts
Aerobic
- Definition: Growing only in the presence of oxygen.
Ambient
- Definition: Natural atmospheric environment.
Angiogram
- Definition: Special type of x-ray that visualizes the blood vessels.
Apneusis
- Definition: Condition marked by maintained inspiratory activity.
Asystole
- Definition: Cessation of ventricular contraction of the heart.
Benign
- Definition: Not malignant; not recurrent; favorable for recovery.
Bronchiectasis
- Definition: Chronic dilation of the bronchi or bronchioles, marked by fetid breath and paroxysmal coughing with the expectoration of mucopurulent matter.
Cardiac Tamponade
- Definition: Acute compression of the heart due to effusion of fluid into the pericardium or the collection of blood in the pericardium from rupture of the heart or a coronary vessel.
Congestive Heart Failure
- Definition: Failure of the heart to maintain an adequate output, resulting in diminished blood flow to the tissues and congestion in pulmonary and/or systemic circulation.
Cyanosis
- Definition: Any bluish discoloration of the skin; associated with blood oxygen deficiency.
Distal
- Definition: Away from the point of origin; downstream.
Dyspnea
- Definition: Difficult or labored breathing.
Empyema
- Definition: Accumulation of pus in a cavity of the body, especially the chest.
Exudate
- Definition: Fluid that accumulates as a result of inflammation.
Heart Failure
- Definition: Sudden fatal cessation of the heart's action; the clinical condition resulting from the inability of the myocardium of the ventricles to maintain an adequate flow of blood to all the tissues of the body.
Heparin
- Definition: Macromolecule polysaccharide acid found in various tissues, especially abundant in the liver; used as a medication that prolongs the clotting time of blood.
Hypercapnia
- Definition: Excess of carbon dioxide in the blood.
Hypoxia
- Definition: Deficiency of oxygen in the tissues.
Ion
- Definition: An atom or group of atoms that has acquired an electric charge through a gain or loss of an electron or electrons.
Manometer
- Definition: Instrument for measuring pressure.
Orthopnea
- Definition: Inability to breathe unless in an upright position.
Perfusion
- Definition: Blood flow.
Pleura
- Definition: Serous membrane that invests the lungs and lines the thoracic cavity, enclosing the pleural cavity.
Polycythemia
- Definition: Excess of red corpuscles in the blood, often seen in patients with chronic cardiac or pulmonary diseases due to arterial oxygen unsaturation.
Pulmonary Circulation
- Definition: Blood circulation that carries blood from the right ventricle to the lungs and returns oxygenated blood to the left atrium of the heart.
Radiolucent
- Definition: Allowing for the passage of X-rays.
Resonance
- Definition: Prolongation and intensification of sound produced by the transmission of its vibrations to a cavity, especially a sound elicited by percussion.
Shunt
- Definition: Bypass; a direct communication between arterial and venous circulation or perfusion of unventilated alveoli.
Stenosis
- Definition: Narrowing or constriction, especially of a lumen or orifice.
Syndrome
- Definition: Group of signs or symptoms that, when considered together, characterize a disease.
Tachypnea
- Definition: Abnormally rapid rate of breathing.
Vapor
- Definition: A gas, especially the gaseous form of a substance that at ordinary temperatures can be converted to a liquid.
Ventilate
- Definition: Movement of gas into and out of the lungs.
Vital Signs
- Definition: Living signs, such as temperature, pulse, respiration, and blood pressure.
