Q

Cardiac Cycle

A

Atrial systole - right and left atria contract

atrial diastole - atria repolarize

ventricular systole - right and left ventricles contract

preload - tension in ventricular wall at end of diastole. reflects the venous filling pressure that fills L ventricle during diastole

afterload - forces that impede the flow of blood out of the heart, primarily pressure in the peripheral vasculature

Q

Hemoglobin

A

“Teens” g/dL

critical values = < 5-7 or >20 g/dL

17
Q

Hematocrit

A

“40s”
ciritcal values = < 15-20% or >60%

% of RBC in total blood volume
low = anemia, blood loss and vitamin or mineral deficiencies
high = dehydration, polycythemia (too many RBC)

18
Q

Partial Thromboblastin Time (PTT)

A

26 - 39 seconds

19
Q

Anticoagulant agents

A

Heparin

Coumadin

20
Q

Antihyperlipidemia agents

A

Lipitor
Zocor

breakdown LDLs, decrease trigylcerides and increase HDLs

21
Q

Beta blockers

A

Tenormin
Lopressor
Inderal

decrease O2 demand by decreasing HR and contractility

22
Q

Calcium channel blockers

A

Procardia
Cardizem

decreases O2 demand for the heart, decrease contraction and vasodilation

23
Q

Dieuretic agents

A

Diuril
Lasix

increase excretion of sodium and urine which decrease blood pressure

24
Q

Nitrate agents

A

Nitrostat
Nitroglycerin

decrease ischemia through smooth muscle relaxation and dilation of peripheral vessels

25
Q

Antihistamine

A

Benadryl

Allegra

26
Q

Anti-inflammatory agents

A

Pulmicort
Cromolyn
Sodium

reduces airway edema

27
Q

ABI index

A

checks for peripheral artery disease

>1.3 = rigid arteries
1-1.3 = normal
0.8-0.99 = mild blockage
0.4-0.79 = moderate blockage
<0.4 = severe blockage
28
Q

32
Q

Heart sounds

A 
S1 = ventricular systole
S2 = ventricular diastole
S3 = vibrations of ventricle walls from atria filling of diastole
S4 = vibration of ventricular wall with ventricle filling and atrial contraction
33
