Chest Flashcards
projection? & pt Position?
PA projection
Upright chest
when Is the pt placed in Upright position of Chest and why?
whenever possible
~To PREVENT engorgement of Pulmonary vessels & to allow gravity to depress Diaphragm
Also Shows AIR & Fluid Lvls
Projection? & Pt Position? How can you tell?
PA Chest
PRONE chest (RECUMBENT)
Diaphragm is superior
compresses thoracic viscera which prevents full expansion of lungs
Projection? & Pt Position? How can you tell?
PA Chest
PRONE chest (RECUMBENT)
Diaphragm is superior
compresses thoracic viscera which prevents full expansion of lungs
For PA Chest in recumbent (Prone) position the difference in Diaphragm movement is not great in ________ individuals it is marked in _______ individuals.
Hyposthenic & Hypersthenic
The ____ Lateral Position Chest position is most common. because…
LEFT
~places Heart closer to IR resulting in less magnified heart image
A slight amount of rotation from. PA or Lateral projection causes…
considerable distortion of the heart shadow
respiration for. PA chest
Full. inspiration, exposure made @SECOND full inspiration
Deep. Inspiration causes the diaphragm to. _____ ________ resulting in…
move inferiorly
~ elongation of heart
(Radiographs of heart should. be. taken @ end. of. normal inspiration to prevent distortion)
MORE AIR =INHALED during SECOND breath (& w/o. strain vs 1st
When pneumothorax is suspected …
One exposure made @END of Full inspiration
&
Another @END of Full expiration
To show: small amounts of free air in pleural cavity tht might be obscurred on inspiration exposure
Inspiration & Expiration Radiographs are used when…
~pneumothorax is suspected &
~to show movement of diaphragm,
~presence of foreign body
~Atelactasis (Absence. of free Air)
The ____ Projection of Chest most common and is used in all …& ____ Projection is usually ordered…
PA
~lung & heart exams
Lateral
~in conjuction w/PA
Right & Left obliques may be used…
required to supplement the PA
Improvised variations. of the basic positions necessary to project localized area free of superimposition
Normally chest Radiography uses ____ kVp to
& can be ____ if
HIGH KVP to penetrate & show all thoracic anatomy
LOWERED IF exposures made w/o. grid
An. apprpriate kVp will…
penetrate mediastinum to show faint image of spine & demonstrate pulmonary vascular markings of lung periphery
