Summary Introduction
To review:
Production and uses of Korotkoff sound.
Introduction:
Blood pressure is that force by which blood moves through the vessels of the circulatory system. It is very important for body because antibodies, white blood cells and hormones travel through blood. The readings of normal blood pressure are 120mmHg (millimeters of mercury) systolic and 80mm Hg diastolic.

What are the sounds of Korotkoff due to? Describe the basic sequence of events of taking someone’s blood pressure using a manual sphygmomanometer.
Calculate the mean arterial pressure (MAO) and pulse pressure for a person with a blood pressure of 115/73.
Note in part (a) that the normal resting value on this pressure–frequency curve is on the steepest, center part of the curve. What is the physiological significance of this?

- Given the variation in pressure with height, in clinical medicine human blood pressure is normally referenced to heart level. Does this usually affect the pressure recorded from the upper arm?arrow_forwardDescribe the reason why someone would be having shortness of breath from congestive heart failure and peripheral edema using Starling forces terminologyarrow_forwardNewer clinical guidelines suggest using a cut-point value of 120 mmHg for systolic blood pressure to identify a person as being hypertensive. However, some clinicians and researchers have suggested increasing the cut-point value for systolic blood pressure to 130 mmHg to identify hypertension (i.e., those with systolic blood pressure of 130 mmHg and above would be positive for hypertension). If the cut-point value for identifying a person as hypertensive was increased from 120 mmHg to 130 mmHg, which of the following may occur? A. The sensitivity of the new cut-point value would increase. B. The specificity of the new cut-point value would increase. C. Both the sensitivity and specificity of the new cut-point value would increase. D. There would be no change to the sensitivity or specificity of the new cut-point value.arrow_forward
