NURS 225 Chapter Notes - Chapter 31: Mean Arterial Pressure, Pulse Pressure, Natriuresis
Document Summary
Name: kendra henry: define the following terms: Systolic blood pressure: the pressure at the height of the pressure pulse; measures the pressure in your blood vessels when your heart beats. Diastolic blood pressure: lowest pressure; measures the pressure in your blood vessels when your heart rests between beats. Pulse pressure: difference between the systolic and diastolic blood pressure. Mean arterial pressure: represents the average pressure in the arterial system during ventricular contraction and relaxation and is a good indicator of tissue perfusion. Natriuresis: excretion of sodium in the urine: describe the 3 ways the autonomic nervous system controls blood pressure regulation. Intrinsic circulatory reflexes: located in the circulatory system and are essential for rapid and short-term regulation of blood pressures. Include bp respsonses with factors such as pain and cold. Vasopressin: aka antidiuretic hormone and is released from the posterior pit.
