Weeks 1-4 questions Flashcards
1
Q
what are the early stages of cardiovascular manifestations during an MI
A
- increased BP and HR
- later phase BP decreases
2
Q
ECG findings during a STEMI
A
- compare to first finding
- ST elevated
- inverted T wave
- pathological Q wave that stays
3
Q
MI managements
A
- MONA
- angioplasty
- fibrinolytic therpy
- beta blockers, arbs, ace, statins
4
Q
hemodynamics of acute heart failure
A
- increased afterload
- increased prelaod
- decreased CO
- decreased gas exchange
5
Q
CPAP on hemodynamics
A
- helps with oxygenation
- decreases preload and afterlaod increasing CO
6
Q
how does Bipap work on hemodynamics
A
ventilation and oxygenation
7
Q
dobutamine does:
A
- increase CO
- vasodilator
8
Q
milrione inotropic does:
A
- increases contractiltiy
- decrease preload and afterload
9
Q
what does intra aortic balloon pump work on
A
- systolic: increase CO, CA perfusion, decrease worload
- diastole (inflates)
10
Q
what is a pulmonary embolism
A
- embolus in lung capillaries
- due to DVT, AFIB, Surgery, immobility, oral contraceptives, HF
11
Q
what happens to hemodynamics during PE
A
- increased afterload, prelead
- decreased contractlity, CO
12
Q
what is a pneumothroax
A
- air in pleural space
13
Q
what happens to hemodynamics during a pneumothorax
A
- increased V/q mismatched, HR
- decreased preload, contractility, SV, CO, BP
14
Q
clinical manifestations of a pneumothorax
A
- decreased PaO2 and SaO2
- sharp chest pain on one side
- mdiastinal displacement
15
Q
what is a pleural effusion
A
- fluid or blood in pleural space
