An LAO position is equivalent to _______ position
RPO
When performing and RAO position of the chest, which lung will be BEST demonstrated?
Left
Proper respiration for routine chest radiograph is
DOUBLE INSPIRATION
If performing a Ventral Decubitis position the patient is laying ________
Prone (face down)
If performing a dorsal decubitis then the patient is laying
Supine (on back/face up)
During a decub: how long should a patient lie in required position BEFORE a radiograph is taken and why?
About 5 minutes to let air rise and fluid settle
WHAT MAKES A DECUB?
- RECUMBENT PATIENT 2. HORIZONTAL CR 3. VERTICLE IR
Degree of a “steep” chest oblique
Greater than 45 degrees
Degree of a “shallow” chest oblique
Less than 45 degrees
In a LAO which lung is best demonstrated
Right
Why is a PA radiograph preferred over an AP?
less magnification of the heart
Routine when visualization of a PICC line is necessary?
PA Only
One reason a line would be inserted into chest cavity?
Medication
The CR should be directed at what level during a soft tissue lateral neck procedure?
C4
What is being visualized in a soft tissue lateral neck radiograph?
- Foreign bodies 2. pharynx 3. upper esophagus 4. larynx
Breathing instructions for a soft tissue lateral neck?
Inspiration phase of quiet nasal breathing
Two things that can be demonstrated during a right or left lateral decub
- Fluid levels/free air 2. previously obscured pulmonary areas
The CR should be directed where for an oblique chest view on a prone patient?
Perpendicular at the center of the IR @ the level of T7 and 2” off the MSP toward elevated side
When doing an oblique view the CR should be how many inches off the MSP and in which direction?
2” off the MSP toward ELEVATED side
- Why should a patient be elevated during a decub? 2.How is this achieved?
- To move patient up off mattress and move out of view of rails 2. With a 2-3” decub sponge/pad
When performing a soft tissue lateral neck procedures what should be done with technique?
decrease 10kV
Example of a “positive” contrast used radiology and what color will it appear on finished radiograph?
Barium. It will show up white
If a patient has excessive fluid in their right lung what type of decub should be done?
Right Lateral
Medical Term for “enlarged adenoids”
adenoidal hypertrophy
When performing a chest X-Ray where should the CR be directed?
T7
Why should shoulders be rolled forward?
to remove scapular shadows from lung field
Removal from clavicles from apices
Lindblom Method Lordotic Position
You should tell a child to pretend to do what during a soft tissue lateral neck exam?
“Smell a Flower”
Term used to describe the area of the chest cavity that contains all the thoracic structures EXCEPT lungs and pluera
Mediastinum
Number of Lobes in 1. Right Lung 2. Left Lung
- 3 2. 2
Which bronchus is shorter, wider, and more vertical?
Right
Which side of diaphragm is higher and why?
The right side due to the placement of the liver
How to determine proper rotation of chest exam?
SC joints aligned
View of a properly aligned lateral chest exam?
Superimposition of the ribs
Why should a filter be used in a decub and why should it be used?
Should be placed to thin part of body, air filled lungs, side that is up. BECAUSE it evens out density
What degree should a patient be oblique if great vessels are being demonstrated?
55-60 degrees
Label
- APICES
- Fluid level
- Heart
