| Question | Answer |
|---|---|
| arterial blood gases | Test used to assess the levels of oxygen and carbon dioxide in the blood |
| auscultation | Process of listening for sounds in the body; especially useful for detecting abnormal sounds in the thoracic cavity. |
| bronchoscopy | Visual examination inside the bronchi using a scope. |
| chest X-ray (CXR) | Radiographic image of the lungs and heart; often done with anterior, posterior, and lateral views |
| oximetry (SpO2) | Use of a noninvasive device, called an oximeter (ahk-SIH-meh-ter), to measure blood oxygen level. The oximeter is placed on a patient’s finger or earlobe. |
| polysomnography (sleep apnea study) | Monitoring of a patient during sleep to aid in diagnosing apnea or other sleep disorders; also called a sleep study. |
| pulmonary angiography | X-ray visualization of arteries and veins using a contrast agent (dye) injected into the patient’s bloodstream. |
| pulmonary function test (PFT) | A group of tests performed to measure airflow into and out of the lungs, lung volumes, and gas exchange between the lungs and the bloodstream. |
| spirometry | Measurement of air capacity in the lungs using a device called a spirometer. |
| sputum culture and sensitivity | Test in which secretions from the lungs are placed in a growth medium, observed for bacterial reproduction, and then tested for antibiotic effectiveness. |
| sputum cytology | The microscopic examination of lung secretions for the presence of malignant (muh-LIG-nuhnt), or cancerous, cells. |
| sweat test | Test that aids in the diagnosis of cystic fibrosis (CF) by measuring the amount of chloride (sodium) present in sweat. |
| tuberculin (TB) skin test (Mantoux tuberculin test) | Injection of a tuberculin-purified protein derivative (PPD) under the skin to determine whether or not a person has been exposed to tuberculosis (TB). |
| ventilation/perfusion (V/Q) scan | A nuclear medicine diagnostic procedure in which radioactive air is inhaled by the patient, and the lungs are observed to determine whether or not they are filling with air. A radioactive dye is injected into the patient to trace blood flow. |
