Geriatric Chest Flashcards
1
Q
Why 72”?
A
- reduce magnification of heart.
- Better detail
2
Q
Why erect?
A
- Air/fluid levels
- Gravity pulls diaphragm down.
- Prevent engorgement of pulmonary vessels.
3
Q
CR=
A
T7
3-4” below jug notch
7-8” below C7
4
Q
PA Anatomy EC
A
- Both lungs from apices to a=costo angles.
- Air-filled trach from T1 down.
- Hilar region
- Heart
- Great vessels
- Bony thorax
5
Q
PA Position EC
A
- Chin not superimposing apices.
- Shoulder rotation to prevent scapulae from being superimposed.
- Both SC jts = distance from spine.
- Distance from lat rib margins =
- 10 post ribs above diaphragm.
6
Q
PA Exposure EC
A
- No motion.
- Vascular markings
- Vertebrae visible through heart shadow
7
Q
Lateral CR
A
Midthorax
T7
8
Q
Lateral Anatomy EC
A
- Entire lungs from apices to angles.
- Sternum to post ribs.
9
Q
Lateral Position EC:
A
- Chin & arms not superimposing.
- No rotation.
- Post ribs & cost angles on side away are 1’2” post due to divergent ray.
- Hilar region in center.
10
Q
Lateral Exposure EC:
A
- No motion.
- Sharp outlines.
- Long scale of contrast = rib outlines & lung markings through heart shadow & upper lung areas w/o overexposing other lung regions.
