Pleural Space Flashcards
What type of pleura covers the inner inner surface of the thorax?
Parietal pleura
What type of pleura covers the lung parenchyma?
Visceral pleura
T/F:
Left and right pleural sacs are open
FALSE!
closed
The regions between the lung lobes that produce lines
on radiography
Pleural Fissure Lines
Dyspnea, thoracic cavity distension, and dyssynchonous
breathing are all clinical signs of the presence of
pleural fluid
Fluid in the pleural space is known as
pleural effusion
Gas is the pleural space is known as
pneumothorax
A pleural effusion detected with a ________ ________
indicates severe disease and a poor prognosis
peritoneal effusion
T/F:
Diaphragmatic hernias can cause pleural effusion,
fluid in the pleural space
TRUE
What radiographic signs are seen with pleural effusion?
_____ interlobular fissures
_______ opacity between lungs and thoracic wall and dorsal to the sternum
_________ of lungs from thoracic wall
_________ of lung margins
Silhouetting of the ______ in DV view
______ of the diaphragm
What radiographic signs are seen with pleural effusion?
WIDE interlobular fissures
SOFT TISSUE opacity between lungs and thoracic wall and dorsal to the sternum
RETRACTION of lungs from thoracic wall
Scalloping of lung margins
Silhouetting of the HEART in DV view
SILHOUETTING of the diaphragm
Which disease is indicated by the following signs?
Pleural fluid
Severely rounded lung lobe margins that do not return
to normal shape following thoracocentesis
Restrictive Pleuritis
___________ is a common cause of UNILATERAL
distributions of pleural fluid
Pyothorax
This type of pneumothorax occurs with
free communication between pleural space and environment
OPEN pneumothorax
This type of pneumothorax occurs when air
leaks into the pleural space via the
lung, trachea, bronchii, esophagus, or mediastinum
CLOSED pneumothorax
In this type of pneumothorax, pleural pressure is
greater than atmospheric pressure
resulting in a continuous influx of air on inspiration that does not
return to lung on expiration
TENSION pneumothorax
In this type of pneumothorax
pleural pressure = atmospheric pressure
Normotensive pneumothorax
Trauma is the most common cause of pneumothorax, and this usually
results in ___________ pneumothorax
Normotensive
Pneumothorax and pleural effusion is usually
_____lateral
BILateral
pneumothorax is easier to see on _______ view
lateral
If on radiography, you see the following, what disease is occuring?
Pulmonary vessels that do not continue to the thoracic wall
Lungs retracted from thoracic wall
Gas opacity between lungs and thoracic wall
Loss of sternal contact
pneumothorax
“Loss of Sternal Contact” is seen with pneumothorax.
What does this mean?
It is the dorsal displacement of the heart on lateral view
A greater degree of lung collapse and
_______ of the diaphragm is seen
with Tension pneumothorax
tenting of the diaphragm
What is the best test to find out if pneumothorax was
caused by a ruptured bullae?
CT
What position do you put the patient in for
Horizontal Beam Radiography?
LATERAL recumbency
