Diagnosis

Question 1

The concentrations 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

Answer 1

arterial blood gases

ABGs

Question 2

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

Answer 2

bronchoscope

Question 3

Study based on the accumulation of radioactive isotopes in lung tissue. A ventilation
scan measures ventilation after inhalation of radioactive material. A perfusion scan
measures blood supply to the lungs after injection of radioactive material. Also called
a pulmonary scintiscan

Answer 3

lung scan

Question 4

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

Answer 4

pulse oximetry

Question 5

Tests done to assess breathing, usually by spirometry

Answer 5

pulmonary function tests

Question 6

An apparatus used to measure breathing volumes and capacities; record of test is a
spirogram

Answer 6

spirometer

Question 7

Surgical puncture of the chest for removal of air or fluids, such as may accumulate
after surgery or as a result of injury, infection, or cardiovascular problems. Also called
thoracocentesis

Answer 7

thoracentesis

Question 8

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 to 72 hours indicates an active or inactive TB infection. Also called the
Mantoux (man-TOO) test

Answer 8

tuberculin test
