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.
