A sphygmomanometer (blood pressure cuff) and a stethoscope. The blood pressure cuff will measure systolic and diastolic blood pressure. The cuff has a pressure gauge attached to an inflatable rubber cuff that is connected by a pump . The pump is then used to inflate the rubber cuff to a pressure greater than systolic pressure . That pressure being put on the artery allows it to flatten, and stop blood flow in the artery. The stethoscope is then placed on the brachial artery in the antecubital (bend in elbow). Pressure is gradually released by opening a valve. When blood pressure is greater than the pressure in the cuff, the artery opens and blood flow returns . The person taking the blood pressure will then listen for korotkoff sounds which are caused by the turbulent flow of blood that can be heard until blood flow returns to normal. The first sound heard is the systolic pressure, and the second sound heard is the diastolic pressure. It is measure in millimeters of mercury …show more content…
According to the experiment only part of this hypothesis is true. Exercise will increase blood pressure and heart rate immediately after exercise. Exercise will also cause pulse pressure to increase as well, when measured immediately after exercise. The MAP did increase in some individuals when measured immediately after exercise. However, the MAP decreased in some individuals, when measured immediately after exercise. The MAP value depends on what the diastolic value was. In experiment 1, the variation of blood pressure values depended on age. It also depended on sex, height, weight, health issues and amount of exercise per week. Body position plays an important factor in blood pressure measurements. The blood flow changes (increases or decreases) when standing, sitting or lying. Which means either vasoconstriction or vasodilation; you end up with varying blood pressure values depending on the body’s position, as a
