Blood pressure Flashcards
measure of the pressure exerted by the blood as it flows through the arteries
arterial blood pressure
pressure of the blood as a result of contraction of the ventricles that is the pressure of the height of the blood wave.
systolic pressure
pressure when the ventricles are at rest
diastolic pressure
difference between the diastolic and systolic pressure is called
pulse pressure
normal blood pressure
120/80
a consistently elevated pulse pressure occurs in
arteriosclerosis
represents the pressure actually delivered to the body’s organ
mean arterial pressure (MAP)
normal MAP
70 to 110 mmHg
when the elastic and muscular tissues of the arteries are replaced with fibrous tissue, the arteries lose much of their ability to constrict and dilate. this condition most common in older adults and middle aged
arteriosclerosis
the proportion or red blood cells to the blood plasma is high. this proportion is referred to as
hemotacrit
factors affecting blood pressure
age, exercise, stress, race, sex, medications, obesity, diurnal variations, medical conditions, temperature
a blood pressure that is persistently above normal is called
hypertension
an elevated blood pressure of unknown cause is called
primary hypertension
an elevated blood pressure with known caused is called
secondary hypertension
blood pressure that is below normal
hypotension
