Q

Why is Morrison’s pouch the first window acquired?

What makes fluids stand out quicker on the L side?

A

R pericolic gutter deeper from
Morrison pouch to pelvis

Splenocolic ligament- prevents fluid from flowing freely

17
Q

If there is fluid in the thorax what will be seen on US during the RUQ exam

What is Beck’s Triad

A

Spine sign- fluid allows waves to spine
Normally- air disperses waves, prevents visualization

HOTN Muffled heart JVD

18
Q

What valve is in center image during PSL

What is the next step for PTs if they lose VS due to tamponades

A

Anterior leaflet MV

Thoracotomy- crack the chest

19
Q

What is the next step for PTs w/ cardiac tamponades but stable VS?

Sliding lungs produce ? sign

A

Thoracentesis

Seashore

20
Q

Absence of lung sliding produces what signs?

What sign alternates between seashore and stratosphere sign?

A

Stratosphere/barcode

Lung point w/ M-mode

21
Q

____ + ____= confidence of no PTx

What finding increases suspicion of PTx

A

Lung slide + B-lines

Horizontal reverberation artifacts (A-lines)

22
Q

Z-lines are ___echoic and arise from

What finding represent interstitial fluid and may be searched for in HF PTs

A

Hyper, pleural interface

B-lines- more than 2 start to become pathologic

23
Q

Presence of ___ is 100% specific for a ___ PTx

What do the Sky, Ocean and Beach indicate

A

Lung point
Occult

Sky: soft tissue
Ocean: pleura
Beach: motion artifact* lost during PTx

24
Q

What is the alternate view to the Subxyphoid view

Subcostal view is best for viewing/assessing ?

A

PSL

PEs
IVC size/collapse (sagittal)
EF estimation
Cardiac in/activity

25
Q

Parasternal view is best for viewing/assessing ?

PSL is best for ?

A

Cardiac in/activity
EF estimation

E-point measurement
Valve motion

26
Q

Apical four chamber view is best for viewing/assessing ?

PSA views allows what 4 images to be captures

A

Chamber size
EF estimation

Base/AV MV Papillary Apex
Mercedes Fish

27
Q

What is the advantages of placing PT in LLD for A4C view

This view is better for assessing ?

A

Removes lung artifacts
Heart closer to chest wall

LV function/size

28
Q

What would cause RV to be larger than LV on apical A4C view

Define Apical Wink

A

R heart strain- PE

A4C view w/ flutter at apex/top of screen- suggests PE
Hypokinesis of RV free wall

29
Q

What are the 5 views done during cardiac US and which way is marker facing

What structure runs over the SMA

What structure is in between the SMA and Aorta

A 
Sub-X: R
PSL: L hip
PSS: R hip
A4C: R hip on PMI
IVC: head

Splenic vein heading to IVC

LRV

30
Q

What is the earliest hypovolemic sign seen on A4C view

A

Systolic RA collapse
