IBHRE CEPS (Engineering) EXAM STUDY
GUIDE COMPLETE RATED A.
Left coronary blood flow occurs during what and why
✔✔diastole because diastole releases compressed endocardial capillaries
Where does delay occur in AVN
✔✔upper region (AN-N)
Where are baroreceptors located?
✔✔carotid sinus and aortic arch
neurotransmitter at parasympathetic nerve junctions
✔✔acetylcholine
Carotid sinus massage
✔✔-chronotropic effect
inspiration results in
✔✔increased heart rate and RV stroke volume, increased venous return,
decreased intracardiac pressure
vascular resistance occurs at
✔✔arterioles
,where is blood flow slowest
✔✔capillaries
vessels with greatest cross-sectional area
✔✔capillaries
largest mean blood pressure drop occurs where
✔✔arterioles
Which vessels store largest volume of blood
✔✔systemic veins
which vessels have most smooth muscle
✔✔large arteries
fastest blood flow
✔✔aorta
lowest blood pressure
✔✔SVC / IVC
dicrotic notch
✔✔marks beginning of LV diastole
, arterial pulse pressure
✔✔the difference between systolic and diastolic blood pressure
% of filling volume from different methods
✔✔rapid diastolic filling (suction cup) = 60%
Diastasis (passive filling) = 25%
Atrial kick (active filling) = 15-20%
second heart sound
✔✔closure of semilunar valves
first heart sound
✔✔closing of AV valves
third heart sound
✔✔soft, low-pitched ventricular filling sound that occurs in early diastole
and may be an early sign of heart failure
Ohm's law equation
✔✔V=IR
EKG monitored patient should be __________, monitor chassis should be
___________ (nonconductive). Why
✔✔ungrounded, grounded. Grounded patient would be able to conduct
leakage currents. we dont want this
