Term
cardiovascular indication of a massive PE:
Definition
hypotension; systolic <90 amy be with venous distensions
Term
of the patients with DVT more than __ will develop PE:
Definition
1/2
Term
define Virchow Triad:
Definition
thrombosis in the veins is trigered by: 1. venoustasis
2. hypercoagubility
3. vessel wall inflammation
Term
how would a PE affect the heart?
Definition
increase the right ventricular afterload and decrease pressure going into the left atrium. may lead to heart failure.
Term
embolism may also cause the release of _______, _______ & __________ leading to increased vascular resistance and the work of the right ventricle.
Definition
histamine, prostaglandin, serotonin (vasoconstrictors)
Term
8 risk factors for PE:
Definition
1. Hx of DVT/PE
2. recent surgery
3. recent pregnancy
4. prolonged immobilization
5. malignancy
6. Obesity
7. smoking
8. HTN
Term
2 most prevalent Sx of PE:
Definition
Dyspnea and Pleuritic chest pain
Term
3 most prevalent signs of PE:
Definition
Tachypnea, rales, tachycardia
Term
2 Sx of DVT:
Definition
calf/leg pain/swelling
Term
which labs may be elevated with PE:
Definition
WBC,ESR,LDH,AST,BNP,DDIM,TROP
ABG = RESP ALK
Term
which of the labs is most diagnostic of PE:
Definition
DDIM; <500 will rule out PE,
Term
what is the Gold Standard test for PE:
Definition
angiography
Term
EKG will most often show what in a PE?
Definition
tachycardia
Term
in what instances are the Trop enzymes elevated assoc with PE?
Definition
prolonged hypotension leading to HF
Term
EKG abnormalities exist in __% of patients with PE:
Definition
70%
Term
Atelectasis noted in __% of PEs
Definition
69%
Term
Pleural Effusion detected in __% of PEs
Definition
47%
Term
What are the "classic findings" on radiographs for PEs
Definition
Hampton's Hump & Westermark's Sign
Term
PE AGB shows:
Definition
resp alkalosis
Term
define V/Q scan:
Definition
radioactive compound inhaled and injected radiograph shows V/Q of the lungs.
Term
when is a V/Q scan indicated?
Definition
when the patient has allergies to contrast, pregnancy, < kidney clearance , that would not allow for CT
Term
The gold standard aniography is being replaced by:
Definition
spiral CT
Term
what is the best way to Dx or RO PE?
Definition
algorithm that incorporates: clinical probabbility, DDIM, CT-PA
Term
List the 7 Well's Criteria and their points:
Definition
1. Sx of DVT = 3.0
2. other Dx less likely than PE = 3.0
3. HR >100 = 1.5
4. immobilization/surgery wn<4wks = 1.5
5. Hx of DVT/PE = 1.5
6. Hemoptysis = 1.0
7. Malignancy = 1.0
Term
what is the simplified clinical probability assesment of the Wells Criteria?
Definition
PE likely = >4.0
PE unlikely =
Term
explain the algorithm for PE Dx:
Definition
1. likelyhood of PE w Wells Criteria
2. DDIM
3. Spiral CT (CT-PA)
PE likely>CT>yes or no
PE unlikely>DDIM>(<500)>no, , >500>CT>yes or no
Term
define PERC:
Definition
PE Rule Out Criteria
Term
List the 8 PERC:
Definition
1. <50
2. HR <100
3. sO2% >/= 95%
4. no hemoptysis
5. no estrogen use
6. no Hx of DVT/PE
7. no s/sx of DVT
8. no surgery/trauma requiring hospitalization wn <4wks
Term
3 prevention methods for PE:
Definition
1. antithrobotics in at risk pts
2. graduated compression stockings
3. pneumatic compression
Term
list Tx cascade of PE:
Definition
LMWH>consider throbolytic if indicated for survival>if can't do thrombolytic & it is needed then embolectomy.

If LMWH is contraindicated then IVC filter considered
