Thorax and Abdomen Flashcards
Why do you do the Oblique Ribs?
to see the axillary ribs
Right posterior ribs:
AP and RPO
Right anterior ribs:
PA and LAO
Left photo:
Inspiration, Diaphragm
Right photo, Diaphragm Down
Expiration, Diaphragm Up
Why do we do chest x-rays Erect?
To allow the diaphragm to move down further
Why is the hemidyaphragm positioned more superior, line higher than the other?
Liver is in the way, on the right side
What is this arrow pointing to?
Sternoclavicular Joint,
Way to test rotation on the PA chest x-ray
Which one is recumbent?
The right image, because the diaphragm is not down enough and the heart is engorged
Which one is Upright?
The image on the left
Which one is AP or PA?
Right: AP
Left: PA
(the heart is magnified in the AP)
Erect, Air Fluid Level
The person has their heart on the wrong side.
Situs Inversous
The flow of the heart:
Deoxygenated blood enters the heart by the superior vena cava and the inferior vena cava (veins), the right atrium pumps forcing the blood into the tricuspid valve into the right ventricle, breathe in and breathe out to get oxygenated blood, go back into the lung
The only artery that contains deoxygenated blood:
Pulmonary artery
The Tricuspid valve is on what side:
the right side
The Bicuspid/Mitral valve is on what side?
Left Side
The first blood vessels off of the coronary artery:
right and left coronary arteries
Study, Position, and Breathing
RAO sternum
Shallow breathing, long time, low mA, blur out pulmonary markings, orthostatic breathing
What positions recommend orthostatic breathing?
RAO Sternum
Transthoracic Lateral
Lateral T-Spine
AP Scapula
Why do you do an RAO and if you can’t do an RAO what do you do?
To superimpose the sternum over the heart.
