Q

Complications for DVT

A

PE
Death

17
Q

If a pulmonary embolism is large enough and lodges in the main pulmonary artery or at the branch point of the left and right main pulmonary artery then this causes what cascade of events

A

this enormous pressure back up to the RV
the RV goes into failure
then the patient becomes hypotensive
then cardiac arrests.

18
Q

What is a PE

A

clot that travels and lodges into a pulmonary artery.
(usually from the LE veins)

19
Q

PE is a common and potentially fatal complication of what issue

A

DVT

20
Q

Risk factors for PE are

A

Virchow’s Triad
Stasis
hypercoagulability
injury to vessel wall

21
Q

True/False
PE can be very easy to make a clinical diagnosis

A

FALSE
It is VERY difficult to Dx in a clinical setting

22
Q

What are the S/s for PE

A

Chest pain, tachypnea, and tachycardia.
Hypoxemia
SOB
Signs of DVT
