Chapter 9: Respiratory System; Diagnostic Tests and Procedures

analysis of arterial blood to determine the adequacy of lung function in the exchange of gases

a measure of blood acidity or alkalinity

partial pressure of oxygen measuring the amount of oxygen in the blood

partial pressure of carbon dioxide measuring the amount of carbon dioxide in the blood

examination of a body cavity with a flexible endoscope to examine within for diagnostic or treatment purposes

use of a flexible endoscope, called a bronchoscope, to examine the airways

use of a flexible endoscope to examine the nasal passages and the pharynx to diagnose structural abnormalities such as obstructions, growths, and cancers

removal of a small piece of lung tissue for pathological examination

two-part nuclear scan of the lungs to detect abnormalities of perfusion (blood flow) or ventilation (respiration)

ventilation scan - made as the patient breathes radioactive material into the airways

perfusion scan - made after radioactive material is injected into the blood and circulates to the lungs

nonionizing image of the lung to visualize lung lesions

recording of various aspects of sleep for diagnosis of sleep disorders

to listen; physical examination method of listening to the sounds within the body with the aid of a stethoscope

physical examination method of tapping over the body to elicit vibrations and sounds to estimate the size, border, or fluid content of a cavity such as the chest

direct and indirect measurements of lung volumes and capacities

portion of pulmonary function testing that is a direct measurement of lung volume and capacity

amount of air axhaled after a normal inspiration

amount of air exhaled after a maximal inspiration

measure of the fastest flow of exhaled air after a maximal inspiration

noninvasive 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

x-ray image of the chest to visualize the lungs

computed x-ray imaging of the head is used to visualize the structures of the nose and sinuses

x-ray of the blood vessels of the lungs after injection of contrast material
