Exercise 33 - Pulse + Blood Pressure Flashcards
What happens during systole?
ventricles contracting
What happens to pressure during repolarization?
Pressure drops
What is considered normal blood pressure?
120/80
How do you calculate stroke volume? What is stroke volume?
EDV-ESV; blood pumped out of the heart
What is a complete cardiac cycle?
P wave to P wave
Which valve has the most problems? And why?
Mitral valve, left side of heart is pushing the hardest
What does a whooshing heart sound indicate?
heart mummor due to inverted valve or valve issue
What does a whistling sound indicate?
stenosis
Where is pressure the highest?
Arteries
What is a pulse? Where do we take pulse?
Alternating surges in pressure, Arteries
What BP is considered hypotensive?
140/90
How do you calculate pulse pressure? What is a normal range?
systolic - dystolic; 30-40 is normal range
What is MAP? How do you calculate MAP? What is a normal MAP range?
Pressure that propels blood into tissues; diastolic + 1/3 pulse pressure; 70-110
What is EDV?
Volume of blood in ventricle is greatest at the end of diastole
What is ESV?
Volume of blood in ventricle is smallest at the end of systole
What is the average resting pulse rate?
70-76 beats per minute
What is the apical pulse?
counting of the heartbeats
Pulse defecit
Difference between values, large value indicates cardiac impairment/weakness
The semilunar valves are forced open when ________.
Ventricular pressure exceeds the pressure in the large arteries leaving the heart
The __________ are characteristic sounds that indicate the resumption of blood flow to the artery being occluded when taking blood pressure.
sounds of Korotkoff
The first heart sound heard during the cardiac cycle is associated with ________.
Closure of the AV Valves
Which of the following tools are most commonly used to measure blood pressure indirectly?
sphygmomanometer and Stethoscope
What are the steps for using a sphygmomanometer?
Wrap cuff around arm just above elbow
Place stethoscope on brachial artery
Squeeze bulb and inflate just above systolic pressure
slowly release pressure valve
Record number when sounds of Kar. appear
Record number when sounds of Kar disappear
Where can you listen to the aortic valve?
2nd intercostal space, right sternal margin
Where can you listen to the pulmonary veins?
2nd intercostal space, left sternal margin
Where can you listen to the tricuspid valve?
5th intercostal space, right sternal margin
Where can you listen to the mitral valve?
Apex of heart, 5th intercostal region
