Document Summary
High blood pressure = higher ltration rate in kidneys. Look over slide 1 of powerpoint vessels 3". Pulse is the difference between the diastolic and systolic pressure. What we feel is a pressure wave caused by expansion and recoil of arteries felt at a number of pressure point" areas where we can feel the pulse. Systemic arterial bp is measured indirectly by the auscultatory method" using a sphygmomanometer. Sounds of korotkoff indicate the blood is spurting through the artery. Sounds disappear when the artery is no longer constricted and blood is. Bp peaks in the morning due to levels of hormones. Age, sex, weight, race, mood and posture may vary bp hypotension low bp. Often associated with long life and lack of cardiovascular illness. Is a good thing as long as it"s not caused by an underlying condition and bp doesn"t drop too low. Acute hypotension important sign of circulatory shock.
