pre 2017 hypertension diagnosis values

140/90

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
