Q

asthma

A

a disease characterized by dyspnea and wheezing caused by spasm of the bronchial tubes or swelling of their mucous membrane

37
Q

A

incomplete expansion of a lung or part of a lung; lung collapse. May be present at birth (as in respiratory distress syndrome) or be caused by bronchial obstruction or compression of lung tissue

A

chronic dilatation of a bronchus or bronchi

Q

ABGs

A

arterial blood gases: the concentration of gases, specifically oxygen and carbon dioxide, in arterial blood. Reported as the partial pressure (P) of the gas in arterial (a) blood, such as PaO2 or PaCO2. These measurements are important in measuring acid-base balance

65
Q

bronchoscope

A

an endoscope used to examine the tracheobronchial passageways. Also allows access for tissue biopsy or removal of a foreign object

66
Q

lung scan

A

study based on the accumulation of radioactive isotopes in lung tissue.

67
Q

pulse oximetry

A

determination of the oxygen saturation of arterial blood by means of a photoelectric apparatus (oximeter), usually placed on the finger or the ear; reported as SpO2, in percent

68
Q

pulmonary function tests

A

tests done to assess breathing, usually by spirometry

Q

spirometer

A

an apparatus used to measure breathing volumes and capacities; record of test is a spriogram

A

a skin test for tuberculosis. Tuberculin (PPD), the test material made from products of the tuberculosis organism, is injected below the skin. A hard, raised lump appearing within 48-72 hours indicates an active or inactive TB infection. AKA Mantoux
