CEN Cardiovascular Emergencies - Questions
With Insightful Solutions
New dose for atropine and max dose in cardiac Correct Answer -
1mg dose with max of 3mg
Cardiac output Correct Answer - amount of blood ejected from
left ventricle each minute
Normal cardiac output Correct Answer - 4-8 L/min
Stroke volume Correct Answer - amount of blood ejected from
LV in one contraction
Normal stroke volume for adult Correct Answer - 50-100mL of
blood
Formula for cardiac output Correct Answer - heart rate times
stroke volume
Three things for stroke volume Correct Answer - preload, after
load, contractility
Preload Correct Answer - blood coming into heart-whats left at
end of diastole
How do we measure pressure in vena cava Correct Answer -
CVP
Invasive measurements of right ventricle Correct Answer -
CVP
, Invasive measurement for left ventricle Correct Answer -
pulmonary wedge pressure
Non invasive measurement of right ventricle Correct Answer -
JVD
Non invasive measurement of left ventricle Correct Answer -
lung sounds
Afterload Correct Answer - the pressure the left ventricle must
eject against
How do we measure right ventricular afterload Correct Answer -
pulmonary artery wedge pressure
How do we measure left ventricular afterload Correct Answer -
mean arterial pressure
MAP measurement Correct Answer - 2X diastolic + systolic
divided by 3
contractility Correct Answer - strength of contractility-
measured by ultrasound
heart rate affected by Correct Answer - chronotropes and
dromotropes
preload and afterload are affected by Correct Answer -
vasoconstrictors and dilators
contractility are affected by Correct Answer - inotropes
chronotropic meds do what Correct Answer - cause the SA
node to fire faster
