Respiratory System
| Term | Definition |
|---|---|
| alveol/o | alveolus, air sac |
| bronch/o | bronchus, airway |
| bronchiol/o | bronchiole (little airway) |
| Alveoli | thin-walled, microscopic air sacs that exchange gases |
| pulmon/o | lung |
| pharyng/o | pharynx (throat) |
| incentive spirometry | A common post operative breathing therapy using a specially designed spirometer to encourage the patient to inhale and hold an inspiratory volume to exercise the lungs and prevent pulmonary complications |
| dyspnea | difficulty breathing |
| hypocarbia | deficient level of carbon dioxide in the blood; also called hypocapnia |
| PaCO2 | partial pressure of carbon dioxide |
| Pulmonary angiography | x-ray imaging of the blood vessels of the lungs after the injection of contrast dye |
| CXR | chest x-ray |
| Cardiopulmonary resuscitation (CPR) | Method of artificial respiration and chest compressions to move oxygenated blood to vital body organs when breathing and heart has stopped |
| coron/o | circle or crown |
| cyanosis | bluish coloration of the skin caused by a deficient amount of oxygen in the blood |
| Pulse oximetry | Non-invasive method of estimating the percentage of oxygen saturation in the blood using an oximeter with a specialized probe attached to the skin at a site of arterial pulsation, commonly the finger; used to monitor hypoxemia |
| uvula | small projection hanging from the back middle edge of the soft palate |
| PaO2 | partial pressure of oxygen |
| my/o | muscle |
| polysomnography (PSG) | recording of various aspects of sleep (i.e., eye and muscle movements, respiration, and brain-wave patterns) for diagnosis of sleep disorders (somn/o = sleep) |
| spir/o | breathing |
| parenchyma | functional tissues of any organ, such as the tissues of the bronchioles, alveoli, ducts, and sacs, that perform respiration |
| Thoracoscopy | Endoscopic examination of the plural cavity using a thoracoscope (endoscope for viewing intrathoracic structures) |
| radiology | x-ray imaging |
| pyothorax | accumulation of pus in the pleural cavity; also called empyema |
| Histamine | A chemical in the body that is released by injured cells during allergic reactions and injury causing constriction of bronchial smooth muscle and dilation of blood vessels |
| computed tomography (CT) | CT of the thorax is used to detect lesions in the lung; CT of the head is used to visualize the structures of the nose and sinuses |
| Peak Expiratory Flow Rate (PEFR) | measure of the fastest flow of exhaled air after a maximal inspiration; also called peak flow |
| pector/o | chest |
| PCP | Pneumocystis jiroveci pneumonia |
| hypercarbia | excessive level of carbon dioxide in the blood (capno = smoke; carbo = coal); also called hypercapnia |
| nasopharyngoscopy | use of a flexible endoscope to examine the nasal passages and the pharynx (throat) to diagnose structural abnormalities, such as obstructions, growths, and cancers |
| Anticoagulant | A drug that dissolves, or prevent the formation of, thrombi or emboli in the blood vessels (e.g., heparin) |
| MRI | magnetic resonance imaging |
| lung biopsy (Bx) | removal of a small piece of lung tissue for pathologic examination |
| nose | structure that warms, moistens, and filters air as it enters the respiratory tract; also houses the olfactory receptors for the sense of smell |
| sleep apnea | periods of breathing cessation (10 seconds or more) that occur during sleep, often resulting in snorting |
| nasopharynx | part of the pharynx directly behind the nasal passages |
