Week 2,3 - Chest Positioning Flashcards
Body Habitus:
Hypesthenic: Massive
Body Habitus:
Stenic : Average
Body Habitus:
Hyposthenic: Slender
Body Habitus::
Asthenic: Very slender
4 divisions of respiratory system ?
pharynx (leads air into larynx); trachea; bronchi and lungs
trachea runs from which levels of the vertebrae?
c6 to t5
what types and numbers of each vertebrae
Cervical - 7
thoracic - 12
lumbar - 5
sacral - 5
caudal (coccygeal) - 4
what is anatomy of the rt bronchi?
Its wider and shorter than the lt bronchi, making it more likley to be lodged with a foreign object
What is the carina?
lowest level of trachea where the rt or lt bronchi divide
Medial Boarder of Lungs
Hilum
How many lobes on each lung
Rt. 3 lobes
Lt 2 Lobes
(Rt lung shorter b/c of liver, but more broader)
Position of the trachea (windpipe)
Is anterior to esophagus (when choking on food, it usually goes into the right bronchus)
Right primary bronchus is shorter, wider and more vertical than the left
Chest: Topographic Anatomic Landmarks (Anterior)
- Jugular Notch (use to help center for AP Chest view )
- Xiphod Process (inferior tip of sterum)
Chest: Topographic (palpable) Anatomic Landmarks (Posterior)
- Vertebral Prominens (7th cervical vertebrae) (if the neck is flexed forward, its the first palpable landmark of the spine
Chest: Topographic Anatomic Landmarks (Posterior)
- Scapula: level of T-7 which is mid-thorax centering point for PA CXR
Bony thorax: How many ribs and thoracic vertebrae
12 pairs (24 ribs) and 12
Chest: PA Projection: Patient Position
- Erect Facing IR;
- Dorsal surface of hand on hips and roll shoulders forwards (moves scapulae out of lung field)
- Expose on full inspiration
Chest: PA Projection: IR Placement
1.5 - 2” above relaxed shoulders
Bony thorax: How many ribs and thoracic vertebrae
Chest: PA Projection: CR
Perp. to T-7 w/ a 72” SID
Chest: PA Projection: SS
Air filled lungs, heart, aortic arch, bronchial tree
Chest Lateral Projection: PP
Erect; True Lateral (Left Lateral)
MCP Centered to midline of grid
Extend arms over head
Chest Lateral Projection: IR
1.5 - 2” above shoulders
Chest Lateral Projection: CR
Perp entering at T-7 @MCP
Chest Lateral Projection: SS
Heart, Lungs, Aorta - Done to differentiate lobes, and pulmonary lesions
Chest Lateral View
AP Projection: PP
Supine or Upright
AP Projection: IR
MSP to Midline of grid
1.5 -2” above shoulders
AP Projection: CR
Perp to sternum;
3” inf. to jugular notch
AP Projection: SS
Similar to PA, but everything is magnified
Lung field seems shorter due to abdominal compression
AP VS PA X-ray View
AP or PA Projection RT. or LT Lateral Decubitus: PP
Lay recumbent on either side;
lateral w/ hand raised above the head
AP or PA Projection RT. or LT Lateral Decubitus: IR
1.5 - 2” above shoulders
AP or PA Projection RT. or LT Lateral Decubitus: CR
Perp and horizontal to:
AP: 3” below juglar notch
PA: T-7
AP or PA Projection RT. or LT Lateral Decubitus: SS
Of the chest, including air/fluid levels in a pneumothorax or pleural effusion (mark this side)
AP Decubitus Chest Photo
Lateral Projection RT or LT Dorsal or Ventral
Lateral Projection RT or LT Dorsal or Ventral: PP
Supine or prone; radiolucent sponge under pt;
Lateral Projection RT or LT Dorsal or Ventral: IR
Center Grid to thorax;
Place AFFECTED side on
Lateral Projection RT or LT Dorsal or Ventral: CR
Perp and horizontal entering MCP @ T-7
Lateral Projection RT or LT Dorsal or Ventral: SS
Change in Air/Fluid level and shows pulmonary areas obscured by fluid in standard projection
Chest AP: Axial Lordotic (lindblom) Method / AP Lordotic
Chest AP: Axial Lordotic (lindblom) Method / AP Lordotic: PP
Erect, standing
1 foot in front of IR
upper shoulders are leaning on IR
Chest AP: Axial Lordotic (lindblom) Method / AP Lordotic: IR
IR is 3” above shoulders
IR is 72” SID
Chest AP: Axial Lordotic (lindblom) Method / AP Lordotic: CR
Perp to center of IR midsternum
Chest AP: Axial Lordotic (lindblom) Method / AP Lordotic: SS
Axial projection of lungs to demo. interlobar effusions
interlobar effusions=a loculated collection of fluid
PA Oblique - RAO/LAO Position
PA Oblique - RAO/LAO Position : PP
General + Heart Series
