Your subject's heart rate is 66 bpm, their stroke volume is 63 ml/bt, their mean arterial pressure is 87 mmHg, their pulse pressure is 40 mmHg, the distance from their heart to the top of their head is 42 cm, and the distance from their heart to the bottom of their feet is 131 cm. What is the pressure at the bottom of their feet? (no units required)
187.9
normal pulse pressure values
40-50 mm Hg
what is the normal cardiac output value
5 L/min
You are taking a subject's blood pressure by the auscultatory method on a hot day outside and they just finished exercising in the heat. When you have worked with this patient before, their blood pressure is usually around 116/82. You pump the cuff up until the pressure is 138 mmHg. You then release the pressure from the cuff, while listening for changes in sound as the pressure in the cuff gradually becomes lower. The needle on the sphygmomanometer is moving down and is at 125 mmHg when you hear a relatively loud sound, then it becomes a little softer at around 101, then a little louder again around 91, becomes muffled around 64, and then disappears at 0 mmHg. Based on this information what is their diastolic blood pressure?
64
Your subject's heart is beating once every 0.92 seconds. Their heart is pumping out 6.4 liters of blood from the heart every minute. After every beat of the heart, there is still 49 milliliters of blood left in the ventricle. The minimum pressure recorded during diastole is 70 millimeters of mercury and every time blood is ejected the pressure increases by 32 millimeters fo mercury from this point. What is this subject's rate pressure product? (no units required)
6652.2
A systolic blood pressure of __________ mmHg would be suggestive of hypotension
90
Based on pre-2017 guidelines hypertension could be diagnosed based on a diastolic blood pressure __________ mmHg
90
normal mean arterial pressure
90-100
Your subject's cardiac output is 5.3 L/min , their heart rate is 55 bpm, and their blood pressure is 123/88. What is their stroke volume (use ml, not L)? (no units required)
96.4
Your subject's heart is beating once every 0.94 seconds. Their heart is pumping out 7.0 liters of blood from the heart every minute. After every beat of the heart, there is still 38 milliliters of blood left in the ventricle. The minimum pressure recorded during diastole is 82 millimeters of mercury and every time blood is ejected the pressure increases by 48 millimeters fo mercury from this point. What is this subject's mean arterial pressure? (no units required)
98
how to find mean artial pressure
DBP + 1/3(PP)
how to find rate pressure product
Hr x SBP
how to find pressure in the feet
MAP + (0.77 x cm)
how to find pressure in the head
MAP - (0.77 x cm)
current elevated blood pressure values
SBP between 120-130
mean arterial pressure
average arerial pressure
3rd korotkoff sound
becomes louder again after sharp thudding
2nd korotkoff sound
becomes softer murmur
third heart sound
caused by turbulence associated with rapid filling of ventricles, commonly observed in heart failure
fourth heart sound
caused by turbulence of blood going from atria into ventricles, rarely heard in adults
pulse pressure
difference between the systolic and diastolic pressures
second heart sound
dub sound, produced near the beginning of ventricular diastole caused by closing of SL valves
1st korotkoff sound
fairly sharp thudding sound, the systolic pressure
where is the mitral area
firsth intercostal space at the mid clavicular line
where is the tricuspid area
fourth intercostal space at left sternal border
first heart sound
lub sound produced at the beginning of systole and is caused by the closure of the AV valves and opening of SL valves
in a subject who had aortic stenosis, we would expect to hear?
lub-whistle-dup
what does the 5th korotkoff sound sound like
no sound
where is the pulmonic area
second left intercostal space
where is the aortic area
second right intercostal space
5th korotkoff sound
sound ceases, usually used as diastolic pressure
4th korotkoff sound
suddenly becomes muffled and reduced in intensity. sometimes used as indicator of diastolic pressure
rate pressure product
wat of estimating the myocardial oxygen demand
When we use the auscultatory method for determining blood pressure: a. we are watching the needle to determine when it starts to bounce b. we are listening to heart sounds c. we are listening for Korotkoff sounds d. we are feeling the subject's pulse to see when it resumes e. two of these answers
we are listening for korotkoff sounds
