Q

evaluation criteria of PA CXR:

lots of things

A
  • Entire lung fields must be included.
  • No rotation.
  • Sternal ends of clavicles – should be equidistant from spine.
  • Trachea visible in midline.
  • Scapula projected outside of lung field.
  • 9-10 posterior ribs visible above diaphragm
  • Heart shadow and diaphragm demonstrated without motion.
  • T-spine & posterior ribs visible through the mediastinum.
  • Lung markings visible.
  • Correct radiographic marker out of anatomy of interest
  • Legal ID present
  • Evidence of radiation protection demonstrated

16
Q

insert pneumo with atelectasis

A
  • note shading
  • entire lung is down
  • how would you dx?
  • – bilateral BS; high Peak pressures,
17
Q

air on a CXR will look

A

dark in the space

18
Q

a consolidation /fluid on a CXR will appear

A

bright
white
more consolidation w/no air (dark) space seen

19
Q

“white out “ is indicative of

A

ARDS

20
Q

if you suspect fluid in the lungs, what is the best radiographic angle/image we should get?

why?

A

LATERAL

  • Approx. 200 ml of fluid are needed to detect an effusion in the PA image vs. approximately 75 ml for the lateral.
21
Q

Lateral image can detect what vol of fluid?

A

75 ml

22
Q

PA CXR can detect what level of fluid vol?

A

200ml

23
Q

evaluations criteria for lateral chest x-ray

A
  • Entire lung fields must be included.
  • No rotation.
  • Superimposition of ribs posterior to t-spine.
  • Sternum demonstrated in lateral profile.
  • Arms or soft-tissue not overlapping superior lungs.
  • Long axis of lungs demonstrated in vertical position.
  • Heart shadow & diaphragm demonstrated without motion.
  • Hilum in center of radiograph.
  • Lung markings visible.
  • Legal ID present
  • Correct radiographic marker out of anatomy of interest.

25
Q

what does kyphosis do to the lungs?

A
  • push the lungs posteriorly
  • can’t expand their lungs well
  • prone to PNA, atelectasis, infections
26
Q

A sharp CP angle indicates

A

good lung

  • no effusion
  • no infiltrate

**dull angle indicates fluid

27
Q

perfect position for central line placement:

A

is at the junction of the SVC and RA

  • “Lateral to thoracis spine, inferior to medial end of right clavicle”
28
Q

perfect position for ETT placement

A

is just superior to the carina

29
Q

what kind of anesthesia do we do for a CV pacemaker?

A

conscious sedation / MAC
