Lab XI

A systolic blood pressure of __________ mmHg would be suggestive of hypotension

90

When we talk about a patient's blood pressure, if we do not say otherwise we are referring to pressure in what part of the circulatory system?

systemic arterial presssure at the level of the heart

Your subject has a stroke volume of 101 ml/beat, a heart rate of 111, and a blood pressure of 148/79. What is their cardiac output in L/min? (no units required)

11.2 SV*HR/1000 /1000 because SV is given in ml/beat and it is asking for L/min

Your subject has a cardiac output of 14.7, a heart rate of 155, and a blood pressure of 169/86. What is their mean arterial pressure? (no units required)

113.7 DBP + (1/3)(PP) PP = Systolic - diastolic

Current guidelines in the United States use an SBP cutoff value of greater than or equal to ____________ to diagnose hypertension. (no units required)

130

You are taking a subject's blood pressure by the auscultatory method. When you have worked with this patient before, their blood pressure is usually around 148/80 with a heart rate of 79. How high should you pump up the pressure in the cuff before you begin taking their BP?

173 Add 25 to the systolic blood pressure

What is a typical maximal exercise cardiac output in a trained subject? (use L)

35

What is a typical maximal aerobic exercise DBP for a young, healthy, adult subject?

68

Which of the following is are NOT true about cardiac output?

At rest it is approximately 70 ml/beat

MAP would likely be lowest for which of the following exercises?

cycling at 200 Watts (90% of max)

This immage depicts the SBP, DBP, and MAP response to exercise for the same subject during two different exercises (lines a-f): cycling and arm cranking. Which line is likely the arm crank DBP?

e

This immage depicts the SBP, DBP, and MAP response to exercise for the same subject during two different exercises (lines a-f): isometric bicep curls and sometric knee extensions. Which line is likely the isometric knee extension DBP?

e

DBP would likely be highest for which of the following exercises?

isometric knee extension at 90% of maximum

SBP would likely be highest for which of the following exercises?

isometric knee extension at 90% of maximum

When we use a stethoscope and blood pressure cuff to determine blood pressure, we place the diaphragm of the stethoscope where?

medial antecubital fossa

One of your patients has hypertension and you usually determine that their blood pressure is around 154/90. However, one of your interns usually determines that they have a blood pressure of around 128/90. What might they be doing wrong to get this answer?

they might not be pumping the pressure in the cuff high enough to be able to observe the first Korotkoff sound

Your subject has a cardiac output of 13, a heart rate of 172, and a blood pressure of 149/82. Estimate their heart's oxygen demand. (do not need units)

25,628 HR * SBP

What is a typical value for mean arterial pressure in a healthy adult human?

93.3

Your subject has a cardiac output of 14.1, a heart rate of 146, and a blood pressure of 142/89. What is their stroke volume in ml/beat? (no units required)

96.6 Q/HR * 1000 * 1000 to get ml/beat

This immage depicts the SBP, DBP, and MAP response to exercise for the same subject during two different exercises (lines a-f): cycling and arm cranking. Which line is likely the arm crank SBP?

a

This immage depicts the SBP, DBP, and MAP response to exercise for the same subject during two different exercises (lines a-f): cycling and isometric knee extensions. Which line is likely the isometric knee extension SBP?

a highest line

This immage depicts the SBP, DBP, and MAP response to exercise for the same subject during two different exercises (lines a-f): cycling and arm cranking. Which line is likely the cyclilng SBP?

b second to highest line

When we use a stethoscope and blood pressure cuff to determine blood pressure, we place the diaphragm of the stethoscope over which blood vessel?

brachial artery

This immage depicts the SBP, DBP, and MAP response to exercise for the same subject during two different exercises (lines a-f): cycling and isometric knee extensions. Which line is likely the cycling MAP?
